Remove SPS profiler.
- Conditionals and code blocks. (MOZ_ENABLE_PROFILER_SPS) - Stub out several profiler-only functions.

-// This is a variant of AutoObjectMapperPOSIX suitable for use in
-// conjunction with faulty.lib on Android. How it behaves depends on
-// the name of the file to be mapped. There are three possible cases:
-//
-// (1) /foo/bar/xyzzy/blah.apk!/libwurble.so
-// We hand it as-is to faulty.lib and let it fish the relevant
-// bits out of the APK.
-//
-// (2) libmozglue.so
-// This is part of the Fennec installation, but is not in the
-// APK. Instead we have to figure out the installation path
-// and look for it there. Because of faulty.lib limitations,
-// we have to use regular open/mmap instead of faulty.lib.
-//
-// (3) libanythingelse.so
-// faulty.lib assumes this is a system library, and prepends
-// "/system/lib/" to the path. So as in (1), we can give it
-// as-is to faulty.lib.
-//
-// Hence (1) and (3) require special-casing here. Case (2) simply
-// hands the problem to the parent class.
