libperf: Add PERF_RECORD_MMAP 'struct mmap_event' to perf/event.h
Move the mmap_event event definition to 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 reading and differentiate them from standard PRI*64 macros.
Committer notes:
Fixup the PRI_l[ux]64 macros on 32-bit arches, conditionally defining it
with that extra 'l' modifier only on arches where __u64 is long long,
leaving it aside on 32-bit arches.
