[Freetype] Use of mmap considered harmful

[Juliusz Chroboczek]

Current stable Linux releases do not support mmap from NTFS.

As the default Linux build of FreeType uses mmap for accessing font
files, this means that it is impossible to use font files in place
from an NTFS partition.  As Windows XP gets deployed on desktop
machines, this is going to become ever more of an issue.

Ideally, the mmap streams library in FreeType should fallback to stdio
when mmap fails (currently with ENODEV (!), but don't trust the Linux
kernel people to remain consistent).  Failing that, I would like to
suggest that the default Linux build of FreeType should not use mmap.
