Xi Wang ba931be2af [sfnt] Fix broken pointer overflow checks. 
Many compilers such as gcc and clang optimize away pointer overflow
checks `p + n < p', because pointer overflow is undefined behavior.
Use a safe form `n > p_limit - p' instead.

Also avoid possible integer overflow issues, for example, using
`num_glyphs > ( p_limit - p ) / 2' rather than `num_glyphs * 2'
given a large `num_glyphs'.

* src/sfnt/ttsbit0.c (tt_sbit_decoder_load_image): Implement it.
