Some prototypes in ftvalid.h use `valid' for the variables
typed as FT_Validator. Their implementations in src/base/
ftobjs.c and utilizations in src/sfnt/ttcmap.c do similar.
Some macros in otvcommn.h assume the exist of the variable
`valid' typed as OTV_Validator in the caller.
Mixing these two conventions cause invalid pointer conversion
and unexpected SEGV in longjmp. To prevent it, all variables
typed as OTV_Validator are renamed to `otvalid'.
* src/otvalid/otvcommn.h: Replace `valid' by `otvalid'.
* src/otvalid/{otvcommn.c, otvbase.c, otvgdef.c, otvgpos.c,
otvgsub.c, otvjstf.c, otvmath.c}: Replace `valid' by `otvalid'
if it is typed as OTV_Validator.
(otv_Coverage_validate): Add fourth argument to pass an expected
count value. Update all users.
Check glyph IDs.
(otv_ClassDef_validate): Check `StartGlyph'.
* src/otvalid/otvgsub.c (otv_SingleSubst_validate): More glyph ID
checks.
* src/otvalid/otvmath.c (otv_MathConstants_validate): There are only
56 constants.
(otv_GlyphAssembly_validate, otv_MathGlyphConstruction_validate):
Check glyph IDs.

* Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c,
otvjstf.c}: modified the code to use a different pre-processor trick
to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code
now compiles neatly with Visual C++. The 'otvalid' module has been
put in the Jamfile build again.
(unfinished) `otlayout' module but has been heavily modified to make
it much more compact.
* src/otvalid/*: New module.
* include/freetype/ftotval.h, src/base/ftotval.c,
include/freetype/internal/services/svotval.h: New files.
* include/freetype/config/ftmodule.h: Add otv_module_class.
* include/freetype/config/ftheader.h (FT_OPENTYPE_VALIDATE_H): New
macro.
* include/freetype/internal/ftserv.h
(FT_SERVICE_OPENTYPE_VALIDATE_H): New macro.
* include/freetype/internal/fttrace.h (otvmodule, otvcommon,
otvbase, otvgdef, otvgpos, otvgsub, otvjstf): New trace components.
* include/freetype/ftchapters.h: Updated.
* src/base/Jamfile (Library), src/base/descrip.mms (OBJS),
src/base/rules.mk (BASE_EXT_SRC): Updated.
* docs/CHANGES: Updated.
