Additional update on Pepper IME API and boilerplate thunk/proxy implementation.

BUG=59425
TEST=Check that ppapi_tests compile (with GYP_DEFINES=shared_library, too).

This CL is the second (out of three) part for adding IME support for PPAPI.
It reflects comments from James Su to the previous CL:
http://codereview.chromium.org/7882004.
- Renamed ..._COMPOSTION_START to _IME_COMPOSITON_START.
- Changed to assure GetSegment to return a strictly increasing sequence of
segmentation points from 0 to the length.
and,
- Added the mostly boilerplate code for interfacing with
in-process & out-of-process plugins.
The actual implementation of the IME support will come as
the next and the last part of this series of patches.
