Raph Levien 371e5dbb3f Avoid integer overflows in parsing fonts ...

A malformed TTF can cause size calculations to overflow. This patch
checks the maximum reasonable value so that the total size fits in 32
bits. It also adds some explicit casting to avoid possible technical
undefined behavior when parsing sized unsigned values.
