Enhance strglobmatch() for supporting character classes([CHARS],
complementation and ranges are also supported) and escaped
special characters (\*, \? etc).

Add glob-expression matching support on --del option.
You can use wildcards for specifying deleting events.
e.g.
Clear all probe events:
# perf probe --del '*'
Clear probes on schedule():
# perf probe --del 'schedule*'

strndup is a GNU extension. So dont include string.h without
defining _GNU_SOURCE (it results in a compile error otherwise).
Remove these includes as util.h does it already.

Add argv_split() ported from lib/argv_split.c to string.c and
use it in util/probe-event.c.

in bytes
This patch modifies util/string.[ch] to add new function:
perf_atoll() to parse string representing size in bytes.
This function parses (\d+)(b|B|kb|KB|mb|MB|gb|GB) (e.g. "256MB")
and returns its numeric value. (e.g. 268435456)

For instance:

aes_x86_64 9056 2 - Live 0xffffffffa0091000

Handle that by introducing a strxfrchar routine that replaces
dashes with underscores when matching file names to loaded modules.

On 64-bit powerpc, __u64 is defined to be unsigned long rather than
unsigned long long. This causes compiler warnings every time we
print a __u64 value with %Lx.
Rather than changing __u64, we define our own u64 to be unsigned long
long on all architectures, and similarly s64 as signed long long.
For consistency we also define u32, s32, u16, s16, u8 and s8. These
definitions are put in a new header, types.h, because these definitions
are needed in util/string.h and util/symbol.h.
The main change here is the mechanical change of __[us]{64,32,16,8}
to remove the "__". The other changes are:
* Create types.h
* Include types.h in perf.h, util/string.h and util/symbol.h
* Add types.h to the LIB_H definition in Makefile
* Added (u64) casts in process_overflow_event() and print_sym_table()
to kill two remaining warnings.

Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.
