bug#7385: 24.0.50; Please index defcustom type constructs

In the Elisp manual, you should be able to do `i restricted-sexp RET' to
go to the section that explains that defcustom type construct.  Likewise
for the other type constructs.
 
This should be done at least for those constructs whose names are
unambiguously type constructs (e.g. `choice', `radio, and
`coding-system', but perhaps not `sexp', `cons', and `vector').
This applies also to keywords such as :match-alternatives.
