Drop all contexts the same way.
* Handle multiple calls to fz_drop_colorspace_context() and
fz_drop_font_context().
* Allow missing context in call to fz_drop_aa_context()
and fz_drop_glyph_cache_context().
* Only drop font context objects when dropping the last reference.
* Avoid unnecessary NULL checks.
