Subject: [RFC 0/4] tools lib traceevent: Install fixes

hi,
sending traceevent changes to make this lib installable
under rpm spec.

Basically adding support to:
  - install header files
  - install version links

Having this patchset applied over the fedora source,
I could built following rpms:

  kernel-tools-libs
  kernel-tools-libs-devel

with added libtraceevent stuff:

  $ rpm -ql kernel-tools-libs
  /usr/lib64/libcpupower.so.0
  /usr/lib64/libcpupower.so.0.0.0
  /usr/lib64/libtraceevent.so.1
  /usr/lib64/libtraceevent.so.1.1.0

  $ rpm -ql kernel-tools-libs-devel
  /usr/include/cpufreq.h
  /usr/include/traceevent
  /usr/include/traceevent/event-parse.h
  /usr/include/traceevent/event-utils.h
  /usr/include/traceevent/kbuffer.h
  /usr/lib64/libcpupower.so
  /usr/lib64/libtraceevent.a
  /usr/lib64/libtraceevent.so

and could build following ex.c outside the kernel tree:

  $ cat ex.c 
  #include <traceevent/event-parse.h>

  int main(void)
  {
          struct pevent *pevent = pevent_alloc();
          printf("krava %p\n", pevent);
          return 0;
  }
  $ gcc -o ex ex.c -ltraceevent -ldl
  $ ./ex
  krava 0x10c6010
  $


I'll send out fedora rpm build changes once we decide
on this patchset.

Also available in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  traceevent/install

thanks,
jirka
