It turns out that gperf-3.1 changed types in the generated code in ways
that aren't even trivially detectable without having to generate a test-file.
It's just not worth using tools and libraries from clowns that don't
understand or care about compatibility. So get rid of gperf.

Update the shipped files generated by flex and gperf to support the
explicit use of "---help---" and to emit warnings for unsupported
characters on COMMAND tokens.
As I could not find out which flex/gperf version was used to generate
the previous version, I used flex 2.5.35 and gperf 3.0.4 from
Ubuntu 14.04 - this also leads to the big number of changed lines
in this patch.

"make allnoconfig" exists to ease testing of minimal configurations.
Documentation/SubmitChecklist includes a note to test with allnoconfig.
This helps catch missing dependencies on common-but-not-required
functionality, which might otherwise go unnoticed.
However, allnoconfig still leaves many symbols enabled, because they're
hidden behind CONFIG_EMBEDDED or CONFIG_EXPERT. For instance, allnoconfig
still has CONFIG_PRINTK and CONFIG_BLOCK enabled, so drivers don't
typically get build-tested with those disabled.
To address this, introduce a new Kconfig option "allnoconfig_y", used on
symbols which only exist to hide other symbols. Set it on CONFIG_EMBEDDED
(which then selects CONFIG_EXPERT). allnoconfig will then disable all the
symbols hidden behind those.

kconfig's keyword hash, lexer, and parser define various functions used
only locally. Declare these functions as static, and regenerate the
corresponding generated files.

Kconfig had a synonym "enable" for "select" that was neither documented
nor used.

Add the possibility to import a value from the environment into kconfig
via the option syntax. Beside flexibility this has the advantage
providing proper dependencies.
Documented the options syntax.

Update _shipped files so regular user does not
need to have bison/flex/gperf installed.
Code changes were contained in previous commit.
Used following program versions (on fedora):
bison (GNU Bison) 2.3
flex 2.5.33
GNU gperf 3.0.2

This adds the general framework to the parser to define options for config
symbols with a syntax like:
config FOO
option bar[="arg"]

This simplifies the parser a bit by merging the various symbol types into a
single token and adds the type to the keyword hash.

Use gperf to generate a hash for the kconfig keywords. This greatly reduces
the size of the generated scanner and makes it easier to extend kconfig.
