[lttng-dev] [GIT PULL lttng-ust] Add is_pic field to statedump so_info event.

[Antoine Busque]

The new is_pic field allows a posteriori analyses (babeltrace, Trace
Compass) to know whether to treat an executable as
position-independent code without having to read the ELF header of the
file, as described in the commit messages.

This pull request contains two commits:

 8e8e7a7 Add is_pic field to statedump soinfo event
 ae3cc06 Tests: add tests for lttng_ust_elf_is_pic
