Since strtailcmp() is enough generic, it should be defined in string.c.

Currently util/string.c includes headers in this order: string.h, util.h
But this causes a build error because __USE_GNU definition
is needed for strndup() definition:
% make -j
touch .perf.dev.null
CC util/string.o
cc1: warnings being treated as errors
util/string.c: In function ‘argv_split’:
util/string.c:171: error: implicit declaration of function ‘strndup’
util/string.c:171: error: incompatible implicit declaration of built-in function ‘strndup’
So this patch swaps the headers inclusion order.
util.h defines _GNU_SOURCE, and /usr/include/features.h defines
__USE_GNU as 1 if _GNU_SOURCE is defined.

Mostly used in symbol.c so move them there to reduce the number
of files needed to use the symbol system.
Also do some header adjustments with the same intent.

Add lazy line matching support for specifying new probes.
This also changes the syntax of perf probe a bit. Now
perf probe accepts one of below probe event definitions.
1) Define event based on function name
[EVENT=]FUNC[@SRC][:RLN|+OFF|%return|;PTN] [ARG ...]
2) Define event based on source file with line number
[EVENT=]SRC:ALN [ARG ...]
3) Define event based on source file with lazy pattern
[EVENT=]SRC;PTN [ARG ...]
- New lazy matching pattern(PTN) follows ';' (semicolon). And it
must be put the end of the definition.
- So, @SRC is no longer the part which must be put at the end
of the definition.
Note that ';' (semicolon) can be interpreted as the end of
a command by the shell. This means that you need to quote it.
(anyway you will need to quote the lazy pattern itself too,
because it may contains other sensitive characters, like
'[',']' etc.).
Lazy matching
-------------
The lazy line matching is similar to glob matching except
ignoring spaces in both of pattern and target.
e.g.
'a=*' can matches 'a=b', 'a = b', 'a == b' and so on.
This provides some sort of flexibility and robustness to
probe point definitions against minor code changes.
(for example, actual 10th line of schedule() can be changed
easily by modifying schedule(), but the same line matching
'rq=cpu_rq*' may still exist.)
Changes in v3:
- Cast Dwarf_Addr to uintmax_t for printf-formats.
Changes in v2:
- Cast Dwarf_Addr to unsigned long long for printf-formats.

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.

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)

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.
