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.

When Mercurial accepts more than one revision, they may be specified
individually, or provided as a topologically continuous range,
separated by the ":" character.

The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
revision identifiers. Both BEGIN and END are optional. If BEGIN is not
specified, it defaults to revision number 0. If END is not specified,
it defaults to the tip. The range ":" thus means "all revisions".

If BEGIN is greater than END, revisions are treated in reverse order.

A range acts as a closed interval. This means that a range of 3:5
gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
