The various build lines from libtraceevent and perf mix up during a
parallel build and produce unaligned output like:
CC builtin-buildid-list.o
CC builtin-buildid-cache.o
CC builtin-list.o
CC FPIC trace-seq.o
CC builtin-record.o
CC FPIC parse-filter.o
CC builtin-report.o
CC builtin-stat.o
CC FPIC parse-utils.o
CC FPIC kbuffer-parse.o
CC builtin-timechart.o
CC builtin-top.o
CC builtin-script.o
BUILD STATIC LIB libtraceevent.a
CC builtin-probe.o
CC builtin-kmem.o
CC builtin-lock.o
To solve this, harmonize all the build message alignments to be similar
to the kernel's kbuild output: prefixed by two spaces and 11-char wide.
After the patch the output looks pretty tidy, even if output lines get
mixed up:
CC builtin-annotate.o
FLAGS: * new build flags or cross compiler
CC builtin-bench.o
AR liblk.a
CC bench/sched-messaging.o
CC FPIC event-parse.o
CC bench/sched-pipe.o
CC FPIC trace-seq.o
CC bench/mem-memcpy.o
CC bench/mem-memset.o
CC FPIC parse-filter.o
CC builtin-diff.o
CC builtin-evlist.o
CC builtin-help.o

kbuffer code is for parsing ftrace ring-buffer binary data and used
for trace-cmd. Move the code here in order to be used more widely.

Ingo reported (again!) that 'make clean' on perf/traceevent does not
work due to some reason with system header file. Quotes Ingo:
"Note that the old dependency related build failure thought to be
fixed in commit 860df5833e is back:
make[1]: *** No rule to make target
`/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'. Stop.
'make clean' itself does not work in libtraceevent:
comet:~/tip/tools/lib/traceevent> make clean
make: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by `.trace-seq.d'. Stop.
So I had to clean it out manually:
comet:~/tip/tools/lib/traceevent> git ls-files --others | xargs rm
comet:~/tip/tools/lib/traceevent>
and then things build fine."
Try to fix it by excluding system headers from dependency generation.

Cross compiling perf requires setting ARCH and CROSS_COMPILE variables,
but libtraceevent couldn't detect the changes so it ends up believing no
recompiling is required. Thus the linker failed like:
LINK perf
../lib/traceevent//libtraceevent.a: member ../lib/traceevent//libtraceevent.a(event-parse.o) in archive is not an object
collect2: ld returned 1 exit status
make: *** [perf] Error 1
This patch fixes this by adding TRACEEVENT-CFLAGS file like
PERF-CFLAGS to track those changes.

Ingo reported that libtraceevent doesn't clean out dependency (.d) files
and it can cause a build error when the libgcc package upgraded:
comet:~/tip/tools/perf> make -j
SUBDIR ../lib/traceevent/
make[1]: *** No rule to make target `/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h',
needed by `event-parse.o'. Stop.
make: *** [../lib/traceevent//libtraceevent.a] Error 2
So this patch makes the .d files depends on the source and header files
also, so that it can be re-generated as needed.
NOTE: This code is copied from the GNU make manual page
(4.14 Generating Prerequisites Automatically).

As we use a macro trick to sync each error codes with its description
string, teach [ce]tags to process them properly.
This patch modifies the libtraceevent's Makefile not a kernel one.

Copy over the files from trace-cmd to the Linux tools directory
such that applications like perf and latencytrace can use the
more advanced parsing code.
Because some of the file names of perf conflict with trace-cmd file
names, the trace-cmd files have been renamed as follows:
parse-events.c ==> event-parse.c
parse-events.h ==> event-parse.h
utils.h ==> event-utils.h
The files have been updated to handle the changes to the header files
but other than that, they are identical to what was in the trace-cmd
repository. The history of these files, including authorship is
available at the git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
The Makefile was also copied over, but most of it was removed to
focus on the parse-events code first. The parts of the Makefile for
the plugins have also been removed, but will be added back when the
plugin code is copied over as well. But that may be in its own
separate directory.
