Add soft limit to pixmap allocation.

All image loading functions call the new fz_new_pixmap_with_limit
allocation function, which will return NULL if the total amount of
pixmap memory would exceed a set limit. Other vital pixmap allocations
which are not as easily recoverable (such as font rendering, and the
various buffers in the draw device) ignore the limit.
