libperf: Add PERF_RECORD_MMAP2 'struct mmap2_event' to perf/event.h

Browse Source 
Moving mmap2_event 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;
   */

Adding and using new PRI_lu64 and PRI_lx64 macros to be used for
that.  Using extra '_' to ease up the reading and differentiate
them from standard PRI*64 macros.
