url: generalise HTTPS proxy handling to accomodate Python changes
Python 2.6.3 introduced HTTPS proxy tunnelling in a way that interferes with
the way HTTPS proxying is handled in Mercurial. This fix generalises it to work
on Python 2.4 to 2.6.
Make it possible to debug failed hook imports via use of --traceback
Prior to this change, if a Python hook module failed to load (e.g. due
to an import error or path problem), it was impossible to figure out
why the error occurred, because the ImportErrors that got raised were
caught but never displayed.
If run with --traceback or ui.traceback=True, hg now prints tracebacks
of both of the ImportError instances that get raised before it bails.
