[otvalid] Fix a naming convention conflicting with ftvalid. 

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.
