evolve: prevent a crash in httpclient_pushobsmarkers() when pushing

I've been running into a crash when pushing from my hg repo in a Fedora 16 VM to
Win7 running 'hg serve', even with extensions disabled on both sides:

  ../hg push -r . pc
  pushing to http://192.168.1.4:8000/
  searching for changes
  no changes found
  pushing 2 obsolescence markers (263 bytes)
  ** unknown exception encountered, please report by visiting
  ...
  File "hg-evolve/hgext/evolve.py", line 2482, in _pushobsolete
    remote.evoext_pushobsmarkers_0(obsdata)
  File "hg-evolve/hgext/evolve.py", line 2522, in httpclient_pushobsmarkers
    ret, output = self._call('evoext_pushobsmarkers_0', data=obsfile)
  ValueError: too many values to unpack

I'm not sure how this repo differs from the one in the test suite, so I'm not
sure how to craft a test for this.  The failure occurs even when there _are_
csets to push.  There was no crash if no obsolete markers needed to be pushed.

At any rate, this code was stolen from httppeer._callpush(), where it calls
self._call().  The socket exception handling wasn't necessary to fix the crash,
but the calling code might as well be duplicated in its entirety.

A successful push with this patch looks like this.  Note the final line is _not_
in the output of the http push in test-simple4server.t:

  ../hg push -r . pc
