After freeing each elements of the @values->value, we should free itself
too.

Using %L[uxd] has issues in some architectures, like on ppc64. Fix it
by making our 64 bit integers typedefs of stdint.h types and using
PRI[ux]64 like, for instance, git does.
Reported by Denis Kirjanov that provided a patch for one case, I went
and changed all cases.

Related to a shadowed variable bug fix Valdis Kletnieks noticed
that perf does not get built with -Wshadow, which could have
helped us avoid the bug.
So enable -Wshadow and also enable the following warnings on
perf builds, in addition to the already enabled -Wall -Wextra
-std=gnu99 warnings:
-Wcast-align
-Wformat=2
-Wshadow
-Winit-self
-Wpacked
-Wredundant-decls
-Wstack-protector
-Wstrict-aliasing=3
-Wswitch-default
-Wswitch-enum
-Wno-system-headers
-Wundef
-Wvolatile-register-var
-Wwrite-strings
-Wbad-function-cast
-Wmissing-declarations
-Wmissing-prototypes
-Wnested-externs
-Wold-style-definition
-Wstrict-prototypes
-Wdeclaration-after-statement
And change/fix the perf code to build cleanly under GCC 4.3.2.
The list of warnings enablement is rather arbitrary: it's based
on my (quick) reading of the GCC manpages and trying them on
perf.
I categorized the warnings based on individually enabling them
and looking whether they trigger something in the perf build.
If i liked those warnings (i.e. if they trigger for something
that arguably could be improved) i enabled the warning.
If the warnings seemed to come from language laywers spamming
the build with tons of nuisance warnings i generally kept them
off. Most of the sign conversion related warnings were in
this category. (A second patch enabling some of the sign
warnings might be welcome - sign bugs can be nasty.)
I also kept warnings that seem to make sense from their manpage
description and which produced no actual warnings on our code
base. These warnings might still be turned off if they end up
being a nuisance.
I also left out a few warnings that are not supported in older
compilers.
[ Note that these changes might break the build on older
compilers i did not test, or on non-x86 architectures that
produce different warnings, so more testing would be welcome. ]

If --pretty=raw is given to perf report -T, it now displays one
line per-thread per-counter with the raw event id added.
We get:
# PID TID Name Raw Count
18608 18609 cache-misses 28e 416744
18608 18609 cache-references 28f 6456792
18608 18608 cache-misses 28e 448219
18608 18608 cache-references 28f 7270244
instead of:
# PID TID cache-misses cache-references
18608 18609 416744 6456792
18608 18608 448219 7270244

Improve and fix the handling of per-thread counter stats
recorded via perf record -s. Previously we only displayed
it in debug printouts (-D) and even that output was hard
to disambiguate.
I moved everything to utils/values.[ch] so that we may reuse
it in perf stat.
We get something like this now:
# PID TID cache-misses cache-references
4658 4659 495581 3238779
4658 4662 498246 3236823
4658 4663 499531 3243162
Then it'll be easy to add --pretty=raw to display a single line per thread/event.
By the way, -S was also used for --symbol... So I used -T/--thread here.
perf report: Add -T/--threads to display per-thread counter values
We get something like this now:
# PID TID cache-misses cache-references
4658 4659 495581 3238779
4658 4662 498246 3236823
4658 4663 499531 3243162
Per-thread arrays of counter values are managed in utils/values.[ch]
