sshpeer: use peer interface
We need the same @property conversion of ui like we did for localpeer.
We renamed _capabilities() to capabilities() to satisfy the new
naming requirement.
However, since we're inheriting from wireproto.wirepeer which inherits
from peer.peerrepository and provides its own code accessing
_capabilities(), we need to keep the old alias around. This wonkiness
will disappear once wirepeer is cleaned up in subsequent commits.
We also implement methods for basepeer that are identical to the
defaults in peer.peerrepository in preparation for the removal of
peerrepository.

'''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.
