harmless, but querying could give wrong positive results.

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.

This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,

is used.

Oran Agra 2e7a4e9b7f Position Independent Code (PIC) support in truetype driver.
* include/freetype/internal/services/svmm.h add macros to init
instances of FT_Service_MultiMastersRec.
* include/freetype/internal/services/svttglyf.h add macros to init
instances of FT_Service_TTGlyfRec.

* src/truetype/ttdriver.h declare tt_driver_class using macros from
ftdriver.h, when FT_CONFIG_OPTION_PIC is defined create and destroy
functions will be declared.
* src/truetype/ttdriver.c when FT_CONFIG_OPTION_PIC is defined
the following structs:
tt_service_gx_multi_masters, tt_service_truetype_glyf, tt_driver_class
and tt_services array,
will have functions to init or create and destroy them
instead of being allocated in the global scope.
And macros will be used from ttpic.h in order to access them
from the pic_container.
* src/truetype/ttobjs.c change trick_names array to be
PIC-compatible by being a two dimentional array rather than array
of pointers.

New Files:
* src/truetype/ttpic.h declare struct to hold PIC globals for truetype
driver and macros to access them.
* src/truetype/ttpic.c implement functions to allocate, destroy and
initialize PIC globals for truetype driver.

* src/truetype/truetype.c add new file to build: ttpic.c.
* src/truetype/jamfile add new files to FT2_MULTI build: ttpic.c.
