Make PPAPI headers compile with C compilers (gcc on Linux & Mac and MSVS on Windows). This includes changing bool to PP_Bool and adding a PP_INLINE macro.

TEST=tests/test_c_includes.c
BUG=59791,53451

The first patch set is a straight copy of http://codereview.chromium.org/4019010/show which got LGTMed when PPAPI was in its own repo, but had to be rolled back in order to include chrome changes.

IMPORTANT:  This change will break plugin implementations that use the C interface, and might break others as well.
