  perf symbols: Adjust symbol for shared objects (2016-04-07 17:17:01 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Beautify more syscall arguments in 'perf trace', using the type column in
  tracepoint /format fields to attach, for instance, a pid_t resolver to the
  thread COMM, also attach a mode_t beautifier in the same fashion
  (Arnaldo Carvalho de Melo)

- Build the syscall table id <-> name resolver using the same .tbl file
  used in the kernel to generate headers, to avoid the delay in getting
  new syscalls supported in the audit-libs external dependency, done so
  far only for x86_64 (Arnaldo Carvalho de Melo)

- Improve the documentation of event specifications (Andi Kleen)

- Process update events in 'perf script', fixing up this use case:

    # perf stat -a -I 1000 -e cycles record | perf script -s script.py

- Shared object symbol adjustment fixes, fixing symbol resolution in
  Android (Wang Nan)

Infrastructure:

- Add dedicated unwind addr_space member into thread struct, to allow
  tools to use thread->priv, noticed while working on having callchains
  in 'perf trace' (Jiri Olsa)

Build fixes:

- Fix the build in Ubuntu 12.04 (Arnaldo Carvalho de Melo, Vinson Lee)
