af9eb56bfe perf script: Add new output field 'dsoff' to print dso offset 
This adds a new 'dsoff' field to print dso offset for resolved symbols,
and the offset is appended to dso name.

Default output:

  $ perf script

       ls 2695501 3011030.487018:     500000 cycles:  ffffffff9968e107 [unknown] ([unknown])

       ls 2695501 3011030.487019:     500000 cycles:  ffffffff99e00094 [unknown] ([unknown])
       ls 2695501 3011030.487019:     500000 cycles:      152cc718a8d0 __errno_location@plt+0x0 (/usr/lib/x86_64-linux-gnu/libselinux.so.1)

Display 'dsoff' field:

  $ perf script -F +dsoff

2dbfc94517 perf evsel: Rename perf_evsel__fprintf() to evsel__fprintf() 
As it is a 'struct evsel' method, not part of tools/lib/perf/, aka
libperf, to whom the perf_ prefix belongs.

ca1252779f perf evsel: Introduce evsel_fprintf.h 
We already had evsel_fprintf.c, add its counterpart, so that we can
reduce evsel.h a bit more.

We needed a new perf_event_attr_fprintf.c file so as to have a separate
object to link with the python binding in tools/perf/util/python-ext-sources
and not drag symbol_conf, etc into the python binding.
