Eduardo Habkost fa34a3c58a Use DECLARE_*CHECKER* when possible (--force mode)
Separate run of the TypeCheckMacro converter using the --force
flag, for the cases where typedefs weren't found in the same
header nor in typedefs.h.

Generated initially using:

 $ ./scripts/codeconverter/converter.py --force -i \
   --pattern=TypeCheckMacro $(git grep -l '' -- '*.[ch]')

Then each case was manually reviewed, and a comment was added
indicating what's unusual about those type checking
macros/functions.  Despite not following the usual pattern, the
changes in this patch were found to be safe.
