Fix Savannah bug #43976.
Assure that FreeType's internal include directories are found before
`CPPFLAGS' (which might be set by the user in the environment), and
`CPPFLAGS' before `CFLAGS'.

files handled in `freetype.mk'.

Apply fixes for cppcheck nitpicks.
http://cppcheck.sourceforge.net/
Note that the current version heavily chokes on FreeType, delivering
even wrong results. I will report those issues to the cppcheck team
so that a newer version gives improved results hopefully.
*/* Improve variable scopes.
*/* Remove redundant initializations which get overwritten.
* src/base/ftmac.c ,builds/mac/ftmac.c (count_faces_scalable):

* src/base/ftdbgmem.c (ft_mem_table_destroy): `table' can't be zero.

*/*: 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.

Slightly improve LZW_CLEAR handling.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>:
Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are
handled as clear codes. This also re-sets old_code and old_char to
predictable values, which is a little better than using `random'
ones if the code following LZW_CLEAR is invalid.

Add explicit LZW decompression stack size limit.
Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is
constructed correctly. It's even less than that, see e.g.
libarchive code comment for a better size upper bound:
http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121
This patch adds explicit stack size limit, enforced when stack is
realloced.
An alternative is to ensure that code < state->prefix[code - 256]
when traversing prefix table. Such check is less efficient and
should not be required if prefix table is constructed correctly in
the first place.
* src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.

Protect against loops in the prefix table.
LZW decompressor did not sufficiently check codes read from the
input LZW stream. A specially-crafted or corrupted input could
create a loop in the prefix table, which leads to memory usage
spikes, as there's no decompression stack size limit.
* src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First
code in valid LZW stream must be 0..255.
<FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent,
code > free_ent is invalid.

used to reduce the amount of heap size required to only test wether
we're dealing with a BDF font (the old code allocated 64 Kb right
before any test).

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 !)
