This monster commit was created by applying Nikhil's scripts

followed up by minor manual clean-up.
No change in functionality, of course.

*/*: Use `FT_THROW'.
...
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

Fix reading of signed integers from files on 64bit platforms.
...
Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension. For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.
We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.
* include/freetype/internal/ftstream.h, src/base/ftstream.c

* src/lzw/ftlzw.c (FT_Stream_OpenLZW): modified the function to check
the LZW header before doing anything else. This helps avoid un-necessary
heap allocations (400 Kb of heap memory for the LZW decoder ! Oh my !)

* include/freetype/internal/ftmemory.h, and a lot of other files !!:
...
changed the names of memory macros. Examples:
MEM_Set => FT_MEM_SET
MEM_Copy => FT_MEM_COPY
MEM_Move => FT_MEM_MOVE
ALLOC => FT_ALLOC
FREE => FT_FREE
REALLOC = >FT_REALLOC
FT_NEW was introduced to allocate a new object from a _typed_
pointer..
note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
arguments.
This results in _lots_ of sources being changed, but makes the
code more generic and less error-prone..
