[truetype] Don't trust `maxp's `maxSizeOfInstructions'.

Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see

  http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html

for details.

* src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep'
tables also for setting `autohint'.

* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from
`TT_Process_Composite_Glyph' for handling unreliable values of
`maxSizeOfInstructions'.
