libperf: Add PERF_RECORD_LOST_SAMPLES 'struct lost_samples_event' to perf/event.h
Move the PERF_RECORD_LOST_SAMPLES event definition into libperf's
event.h header include.
In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.
Perf added 'u*' types mainly to ease up printing __u64 values
as stated in the linux/types.h comment:
/*
* We define u64 as uint64_t for every architecture
* so that we can print it with "%"PRIx64 without getting warnings.
*
* typedef __u64 u64;
* typedef __s64 s64;
*/
Add and use new PRI_lu64 and PRI_lx64 macros for that. Use extra '_' to
ease up the reading and differentiate them from standard PRI*64 macros.
