More doc cleanup

Add missing entries to NAME section
Add SYNOPSIS lines, remove old NAME entries
Update find-doc-nits; better regexp's for parsing SYNOPSIS sections.
Rename a couple of files to have an API name.
Remove RSA_private_decrypt; it was duplicate content
Update for recent doc additions

 OBJ_cmp() compares B<a> to B<b>. If the two are identical 0 is returned.
 
 OBJ_dup() returns a copy of B<o>.
