Allow moc to produce the desired identifiers when used with C++
symbol names that have been redefined, for example by -Dfoo=bar.
Two changes are required: firstly, when encoding a type name, the
components of the name must be checked for substitutions that have been
defined for that token (note that this is not done here by correct
pre-processing, but only by processing the resultant table of
definitions). Secondly, the arguments to the SIGNAL, SLOT and METHOD
macros must be allowed to be substituted during macro expansion rather
than stringized directly.
This is a temporary change to prevent breaking existing projects
that depend on the declarative module. After clients have had an
opportunity to update their code to the use the new interfaces,
it can be removed.
