Bug 1358074 (part 2) - Unexport and rename ProfilerState. r=mstange. gPS is declared in GeckoProfiler.h so that it can be tested as non-null in a couple of functions. - These checks are of little value, so this patch removes them. - That lets us remove the ProfilerState and gPS declarations from GeckoProfiler.h. - And, because ProfilerState is now only used within platform.cpp, that lets us rename it as PS, which is how we currently refer to it (via a typedef) within platform.cpp anyway.
