This is essentially how Synaptic works already. Searching ssh python on an FC6
system gives you: cobbler, denyhosts, pexpect, python-paramiko,
python-twisted-conch, rdiff-backup.

Those 2 are essentially the same thing. Unfortunately, Synaptic won't help you
here, but this works:
repoquery -f /usr/bin/hg
as does this:
repoquery --whatprovides /usr/bin/hg
However, both these only work by full path name, searching for just db.h won't
work.
But I think all this could easily be done with the already-available RPM and
repomd infrastructure, which already contains full file lists for all packages
in the repositories. No new packaging system needed, no additions to the
repository even, just some work on the client side. (In fact, you could even
write a shell script which does a repoquery -a, then repoquery -l on all the
results, and greps for the file name in this. But it's a lot faster faster if
you read the metadata in only once, of course.)
