Cleanup: Remove 100+ compiler warnings.
This is a big cleanup that removes compiler warnings by performing
the following:
- Remove unused functions or variables.
- Change pointer cast to be alias safe using unions.
- Use __attribute__((unused)) on some local variable definitions
when their usage depends on conditional defines that are not
always true when compiling the same source several times.
- Fix a couple array indexing bugs.
There are still a few warnings from the JSON lexer, libjpeg and
the TCG helpers though, but the overall compilation is much cleaner.
