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)
