This feature was never used and it is not even working because weak linking
doesn't work in-between files in a library.

This is a quick patch to solve FS#13104, we can not disable the
clickwheel LDO from within interrupt code, so for the moment we
leave it enabled all the time, it is unknown how power comsumption
is affected when the hold switch is locked.

Unlike the current code, it does no looping to count days or do
table lookups, which means running time doesn't increase with year
or month. A good thing if it's call a lot, especially if the
algorithm were asked to compute dates centuries or more from the
epoch start.
As a bonus, handles negative time values.

It is possible to have a thread awoken and subsequently the message
that was placed in the queue has been removed by the time the thread
is able to check the queue. Ensure theads that failed to find a
message do not return prematurely.
It was at worst imprecise when a timeout is specified. It's entirely
incorrect if the function ever returns with SYS_TIMEOUT when using
TIMEOUT_BLOCK.

Chessbox was overflowing GameList[240] causing the board to flip + crash
GameCnt changed to unsigned char which allows the array to roll over
to 0 after 255
define MAX_GAME_CNT 256 and GameList[MAX_GAME_CNT] along with 1 byte GameCnt
should fix this issue
dbg save routine left in for now to help identify any other problems
Added bounds checking to prevent second bug found when loading .pgn files

Fix stuff that was bugging me about the way I did it at first.
While messing around I found RDS code wasn't masking its GPIO
ISR as it should, which might lead to two different interrupts
messing with the static data.

Some drivers set tm_wday just fine and do not need it coerced to
be correct. Others set tm_yday, so don't overwrite what the driver
sets; just zero it inside if it can't fill the field. Move calls
to set_day_of_week() to the sorts of drivers that presumably
required the hammer (FS#11814) in get_time() where the weekday
isn't locked to the date.

1. Slightly revised and regularized internal interface. Callback is used
for read and write to provide completion signal instead of having two
mechanisms.
2. Lower overhead for asynchronous or alterate completion callbacks. We
now only init what is required by the transfer. A couple unneeded
structure members were also nixed.
3. Fixes a bug that would neglect a semaphore wait if pumping the I2C
interrupts in a loop when not in thread state or interrupts are masked.
4. Corrects broken initialization order by defining KDEV_INIT, which
makes kernel_init() call kernel_device_init() to initialize additional
devices _after_ the kernel, threading and synchronization objects are
safe to use.
5. Locking set_cpu_frequency has to be done at the highest level in
system.c to ensure the boost counter and the frequency are both set in
agreement. Reconcile the locking inteface between PP and AMS (the only
two currently using locking there) to keep it clean.
Now works fine with voltages in GIT HEAD on my Fuze v2, type 0.
Previously, everything crashed and died instantly. action.c calling
set_cpu_frequency from a tick was part of it. The rest may have been
related to 3. and 4. Honestly, I'm not certain!
Testing by Mihail Zenkov indicates it solves our problems. This will
get the developer builds running again after the kernel assert code
push.

Add lua code to check whether ei/di and ext instructions are supported. This
is unclear since xburst is somewhere between mips32r1 and mips32r2. Details
results are below, but in summary: they don't work (ei has no effect, di/ext
cause illegal instruction exceptions)

Since we can catch exceptions like data aborts on read/write, it takes very
little to also catch exceptions in calls. When extending this with the catching
of illegal instructions, the call instruction now becomes much more robust and
also for address and instruction probing. Since we can catch several types of
exception, rename set_data_abort_jmp to set_exception_jmp. At the same time,
simplify the logic in read/write request handlers. Also fix a bug in ARM
jump code: it was using
stmia r1, {..., pc}
as if pc would get current pc + 8 but this is actually implementation defined
on older ARMs (typically pc + 12) and deprecated on newer ARMs, so rewrite the
code avoid that. The set_exception_jmp() function now also reports the exception
type.

Now that we now that jz4760b implements EBASE, we can use it to rebase
exceptions to use a k1seg address, that maps to the physical address of the
TCSM0. It requires to enable HAB1 to have this translation. This most the most
inefficient way to access tighly coupled memory ever, but it works.

The JZ misc allows to enable and test SRAM.
The XBurst code uses the coprocessor interface to analyse the cpu. It also
provides a test platform for various features like EBASE and exceptions.
I was able to test and confirm that on jz4760b (thus xburst), EBASE works
(but top 2 bits are not controllable and always 01). The processor claims
to support vector interrupts but this is untested. The values in ConfigX
are not to be trusted blindly, clearly some are wrong. I tried to use the
JZ4780 Config7 "ebase gate" to change bit 30 of EBASE but it does not work,
which suggests that JZ480 uses a newer version of XBurst. Detailled log below:

This is needed on the jz4760b because if some data is loaded to DRAM, then it
is cached and a disaster lurks if dcaches/icache are not flushed. Targets that
needs this must define CONFIG_FLUSH_CACHES in target-config.h and implement
target_flush_caches(). Currently MIPS has some generic code for mips32r1 that
requires to define {D,I}CACHE_SIZE and {D,I}CACHE_LINE_SIZE in target-config.h

The stub is quite versatile: it can be loaded using bootrom or another other
means (like factory boot on Fiio X1). It relocates itself to TCSM0 and provides
basic functionality (it does not recover from failed read/writes at the moment).

This is a register description file for the JZ4760B. There are several
details worth noticing:
- it was obtained by gathering information from several sources/headers, but
since there are inconsistencies between them about the exact differences
between JZ4760 and JZ4760B, this file probably contains some errors
- the register names are not the same as the manual ones (which are not the
same as the one in the headers anyway): I dropped the "R" suffix on most
registers because it's redundant
- Ingenic likes to have read-only registers and then set/clr registers, with
very confusing names like DIR/DIRS/DIRC: in the file, the set/clr registers
are described as set/clr variants of the original register
- Parts of the description were obtained programmatically, which explains why
there are empty nodes or partially undocumented registers

The function is neither reentrant nor ISR callable. Instead of
using a ticked-based timeout, have the button driver provide the
unboost after a delay when waiting for a button.
HAVE_GUI_BOOST gets immediate boost after dequeuing any message,
otherwise the queue has to have at least three messages waiting
for it to trigger a boost-- essentially the behavior that existed
but now combined in one place.

Selective backlight allows the user to choose actions that will not
enable the backlight when pressed.
Advanced softlock allows user to choose actions that will not be
blocked by screenlock on devices without a hold button.
Both only occur in FM and WPS Contexts.
Update:
Back from the dead
-Cleaned up code, removed unnecessary calls, re-arranged last filter action
timeout conditional to work in case last_filtered_action_tick was never set
-Added entries to the manual
-Fixed back button on some menus not activating backlight
-Made menus more intuitive, no actions selected now changes menu item to off.
-Added talk fuctionality.
-Added option to disable selective backlight while on external power.
-Rewrote backlight and softlock handling code to fix issue with scrollwheels
-Menu changed to have toggle(yes/no) and settings
-Optimized selective actions lookup
-Added option to disable notification of 'buttons locked' while softlocked
-Removed uneeded code, consolidated action lookup to single function
-Fixed incorrect name on selective softlock menu
-Added option to disable touch on touchscreen devices

-Fixed Conditional argument In wrong place causing players without
backlight to fail to build
-Fixed Disable Unknown blocking detection of context change
-Fixed canceling menu didn't update new settings
-Added Autolock on backlight off
-Removed backlight_on_force from backlight.c, Now sets ignore next to false
and uses backlight_on
-Cleaned up autolock code added strings to lang file

-Removed old softlock code, Cleaned selective actions code
-Changed menu to match existing RB menus
-Fixed Backlight_on_Hold blocked by backlight_ignore_next
-Fixed ignore_next for ipod
-Fixed bug allowing context with softlock to bypass selective backlight
-Changed mask_select to no longer prompt for changes to be saved
-Changed menu names
-Added ignore timeout to allow ipod scroll wheel to work properly and other
players to still work properly, removed some previous code including
ignore_event
-Increased ignore timeout to prevent sd card accesses from interrupting action
code and turning on backlight
-Changed Unknown action to unmapped action in menu, changed handling code
-Removed unneeded logic and variables for handling unfiltered actions
-Reverted unmapped action code to previous functionality
-Added manual entries (thanks JohnB)
-Removed elusive unhandled unicode character from manual, changed formatting slightly
Actions:
Volume,Play,Seek,Skip
Extras:
Disable unmapped actions
Disable selective backlight on external power
Disable touch during softlock on touchscreen devices
Disable softlock notifications (power button still notifies)
Autolock on backlight off
Method:
Adds a function to ignore backlight on next call
If selected action occurs backlight is forced on,
Filter_first_keypress stays intact.
Selective softlock allows selected actions through, bypasses the normal
softlock routine.
ToDo:
DONE
previous commit (#1) has attribution for folder_select.c which mask_select

Playlist dircache references should be back in working order.
Reenabling dircache references in the database ramcache is not
yet done as it requires quite a bit of rework. Otherwise, the
database in RAM is functional again.
Some buffer compatibility changes have been made for database
commit because the dircache buffer can no longer be stolen, only
freed by an API call.

The file system rework introduced incompatibility between dircache
and the tagcache ramcache and playlist dircache path caching. This
update makes changes to filesystem code to reintegrate all that.
It also fixes a couple bugs that were found when vetting all the
code. The filestream cache was being reset without regard to
the stream even if it was shared in write mode (made work of
.playlist_control). Better handling of unmounting gives files a
better go at force-closing them without risk to disk integrity.
Did some miscellaneous pedantic changes. Improved efficiency of
testing a file's existence (a little) since the path parser will
be shared between file code and parsing for the sake of finding
dircache references, not duplicated as before.
This commit doesn't reenable said items just for the sake of
keeping changes separate and related.
Plan for the next is to enable dircache again for the playlists
(easy peasy) and reenable tagcache ramcache but *without* the
dircache path caching because it's rather substantial to change
in itself. The ramcache will still function without dircache.
