pycompat: alias urllib symbols directly
urllib.request imports a bunch of symbols from other urllib
modules. We should map to the original symbols not the
re-exported ones because this is more correct. Also, it
will prevent an import of urllib.request if only one of
the lower-level symbols/modules is needed.

tests: clean up bad extension
The presence of the "babar" extension breaks subsequent tests.
So delete the file and create an empty one to return the config
to sanity.

perf: perform a garbage collection before each iteration
Currently, no explicit garbage collection is performed when running
the microbenchmarks in `hg perf`. I think this is wrong because
garbage collection can have a significant impact on execution times.
And, if gc is triggered via the default heuristics, it will
fire effectively randomly during subsequent benchmark iterations
due to variable amount of garbage left over from previous runs.
Running a gc before invoking the measured function will help ensure
state is more consistent across all iterations.
