When we detect a different endianity we swap event before processing.
It's tricky for samples because we have no idea what's inside. We treat
it as an array of u64s, swap them and later on we swap back parts which
are different.
We mangle this way also the tracepoint raw data, wh

This improve the error message so that user can know event-name error
before writing new events to kprobe-events interface.
E.g.
==
#./perf probe -x /lib64/libc-2.25.so malloc_get_state*
Internal error: "malloc_get_state@GLIBC_2" is an invalid event name.

Add __return suffix for function return events automatically. Without
this, user have to give --force option and will see the number suffix
for each event like "function_1", which is not easy to recognize.
Instead, this adds __return suffix to it automatically. E.g.

Some system can return DT_UNKNOWN in readdir's struct dirent::d_type and
we must handle it properly. In this case we can directly check if the
entity we found is directory and skip it.

After perf_evlist__create_maps() being executed, we can get all threads
from /proc. And via thread_map__nr(), we can also get the number of
threads.
With the number of threads, the patch allocates a buffer which will
record the shadow stats for these threads.
The buffer pointer is

Previously the rbtree was used to link generic metrics.
This patches adds new ctx/type/stat into rbtree keys because we will use
this rbtree to maintain shadow metrics to replace original a couple of
static arrays for supporting per-thread shadow stats.

This patchset replaces bitmap_{to,from}_u32array with more simple
and standard looking copy-like functions.
bitmap_from_u32array() takes 4 arguments (bitmap_to_u32array is similar):
- unsigned long *bitmap, which is destination;
- unsigned int nbits, the length of destination bitmap, in bits;
