phabricator: add a `phabimport` command
I've had `alias.phabimport = $hg phabread --stack $1 | $hg import --bypass -`
for a while now, and I suspect others do too. That's limited though, in that it
can't use the information on Phabricator to restore it in the original location,
so I'm making it a first class command.
This doesn't do anything ambitious like that- this is mostly a simplification of
`hg import` to get the equivalent of the alias mentioned above. The `--bypass`
option is hardcoded to be enabled and the message about amending rejects
dropped (rejects aren't created with `--bypass`), because editing patches on
Phabricator seems like an unusual workflow.
This will need other options, like `--obsolete` and `--secret`. I think these
would be more useful as config settings, as I imagine the workflows are pretty
fixed depending on roles. Reviewers who don't queue patches probably never want
`--obsolete`, but may need `--secret`. Reviewers who do will want the former,
but not the latter. I left `--stack` as an option, but that should probably be
a config knob too (or at least default to on)- if the point of this is to avoid
rejects, it doesn't make sense to skip dependencies in most cases.
Evolve is going to need a fix to its wrapping of `cmdutil.tryimportone()`, as it
currently assumes `opts` has an `obsolete` key. It's worked around for now.

'''measure performance of Mercurial commands
Using ``hgperf`` instead of ``hg`` measures performance of the target
Mercurial command. For example, the execution below measures
performance of :hg:`heads --topo`::
$ hgperf heads --topo
All command output via ``ui`` is suppressed, and just measurement
result is displayed: see also "perf" extension in "contrib".
Costs of processing before dispatching to the command function like
below are not measured::
- parsing command line (e.g. option validity check)
- reading configuration files in
But ``pre-`` and ``post-`` hook invocation for the target command is
measured, even though these are invoked before or after dispatching to
the command function, because these may be required to repeat
execution of the target command correctly.
