A Scalable, User-Friendly Source Control System.

When the inhibit extension from mutable-history is enabled, it attempts to
iterate over the rebaseset to prevent the nodes being rebased from being
marked obsolete. This happens at the same time as rebase's
_filterobsoleterevs function trying to iterate over the rebaseset to figure
out which ones are obsolete. The two of these iterating over the same
revset generatorset cause a 'generator already executing' exception. This is
probably a flaw in the revset implementation, since iterating over the same
set twice should be supported.
This regression was introduced in 5d16ebe7b14, since it changed
_filterobsoleterevs to be called before the rebaseset was turned into a
set(). For now let’s just make the rebaseset an actual set again before
calling that function. This was caught by the inhibit tests.
The relevant call stack from test-inhibit.t:
