Add depdb-dyndep --update-{include,exclude} options
These options specify prerequisite targets/patterns to include/exclude (from
the static prerequisite set) for update during match as part of dynamic
dependency extraction (those excluded will be updated during execute). For
example:
depdb dyndep ... --update-exclude libue{hello-meta} ...
depdb dyndep ... --update-exclude libue{*} ...
depdb dyndep ... --update-include $moc --update-include hxx{*} ...
The order in which these options are specified is significant with the first
target/pattern that matches determining the result. If only the
--update-include options are specified, then only the explicitly included
prerequisites will be updated. Otherwise, all prerequisites that are not
explicitly excluded will be updated. If none of these options is specified,
then all the static prerequisites are updated during match. Note also that
these options do not apply to ad hoc prerequisites which are always updated
during match.
