Subject: [PATCH v4 0/2] perf script: Have consistent output for symbol address

The goal of this change is to achieve consistent output for symbol address.
Before this, the raw ip is printed for non-callchain and dso offset for
callchain. Mostly what we expect is the raw ip.

This patch does two changes:
  - Always print raw ip for resolved symbols.
  - Add a new 'dsoff' field if we really need the dso offset, and the
    offset is appended to dso name.

v4:
  o also print 'dsoff' for brstack,brstacksym,brstackoff,etc.
v3:
  o 'dsoff' implys 'dso' field. (Namhyung)
v2:
  o split into two patches. (Adrian)
  o do not print offset for unresolved symbols. (Adrian)

Changbin Du (2):
  perf script: print raw ip instead of binary offset for callchain
  perf: script: add new output field 'dsoff' to print dso offset
