lsprof: support PyPy (issue4573)
PyPy's _lsprof module doesn't export a "profiler_entry" symbol. This
patch treats the symbol as optional and falls back to verifying the
attribute is present on the first entry in the collected data as
part of validation.
There is a chance not every entry will contain the requested sort
attribute. But, this patch does unbust lsprof on PyPy for the hg
commands I've tested, so I assume it is sufficient. It's certainly
better than the ImportError we encountered before.
As part of the import refactor, I snuck in the addition of
absolute_import.
