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.

The __print_symbolic() function takes a sequence of key-value pairs for
pretty-printing a constant. The new kvm:kvm_exit print fmt uses the
expression:
__print_symbolic(..., { 0x040 + 1, "DB excp" }, ...)
Currently only atoms are supported and this print fmt fails to parse.
This patch adds support for expressions instead of just atoms so that
0x040 + 1 is parsed successfully.

If an invalid opcode is encountered in parsing event print format, the
trace-cmd calls exit() without parsing any other events.
This patch adds handling for such an error where the get_op_prio() is
called. If the return value is -1, then the event print format parsing
is skipped and parsing continues.

If an invalid opcode is encountered, trace-cmd exits with an error.
Instead it can be treated as a soft error where the event's print format
is not parsed and its binary data is dumped out.
This patch adds a return value to arg_num_eval() function to indicate if
the parsing was successful. If not, then the error is considered soft
and the parsing of the offending event fails.

Some of the util functions of libtraceevent.a conflict with perf,
such as die(), warning() and others. Move them into event-util.h
that is not included by the perf tools.
Also, as perf compiles with 'bool' the filter_arg->bool needs to
be renamed to filter_arg->boolean.

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.
