[raccess] Modify for PIC build.

Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html

Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
are renamed with `ft_' suffixes.

* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
to `ft_raccess_rule_by_darwin_vfs()'.
* src/base/ftobjs.c: Ditto.

* src/base/ftrfork.c: Declarations of FT_RFork_Rule,
raccess_guess_rec, are moved to...
* include/freetype/internal/ftrfork.h: Here.

* include/freetype/internal/ftrfork.h:
FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
to replace raccess_guess_table[] in both of PIC and non-PIC
modes.
* src/base/ftrfork.c: raccess_guess_table[] array is rewritten
by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.

* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
storage.  (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
the function pointer from `ft_raccess_guess_table' storage in
`BasePIC' structure.
* src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
FT_RACCESS_GUESS_TABLE_GET.
(raccess_get_rule_type_from_rule_index): Add `library' as the
first argument to the function, to retrieve the storage of
`ft_raccess_guess_table' from it.  Also `raccess_guess_table'
is replaced by FT_RACCESS_GUESS_TABLE_GET.
(ft_raccess_rule_by_darwin_vfs): Ditto.
