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.
removing compiler warnings (Visual C++ /W4)
* 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.
