This patch adds a new top level to the auto-hinter's script class
hierarchy. It defines `writing systems' which can contain multiple
scripts.
For example, the `latin' writing system (in file `aflatin.c') is
able to support scripts like Latin, Cyrillic, Armenian, etc., which
can be handled similarly.
Scripts are now named using four-letter OpenType tags.

(autofit_module_pic_free): Add code for service removal.
* src/autofit/afpic.h (AF_SERVICES_GET, AF_SERVICE_PROPERTIES_GET):
New macros which provide necessary syntactical sugar for PIC
support.
Originally FT_DEFINE_{DRIVER,MODULE,RENDERER}() macros were
designed to declare xxx_pic_{free,init} by themselves.
Because these macros are used at the end of the module
interface (e.g. ttdriver.c) and the wrapper source to build
a module as a single object (e.g. truetype.c) includes
the PIC file (e.g. ttpic.c) before the module interface,
these macros are expanded AFTER xxx_pic_{free,init} body
when the modules are built as single object.
The declaration after the implementation causes the redundant
declaration warnings, so the declarations are moved to module
PIC headers (e.g. ttpic.h). Separating to other header files
are needed for multi build.
* include/freetype/internal/ftdriver.h (FT_DEFINE_DRIVER):
