files: speed up `hg files` when no flags change display
It's not the first time I see slowness from this command slow down
tools built on top of hg.
The majority of the time is spent merely printing the result before
this change, which is clearly not how it should be (especially since
the computation of the result also looks slow).
Running `hg files` in mozilla-central:
parent revision: 1,260s
this commit: 0,683s
this commit without batching ui.write: 0,931s
this commit replacing the body of the loop with `pass`: 0,566s
This looks like a prime candidate for a rust fast path, but until
then, it seems reasonable to optimize the python.

sshpeer: make client print (likely) server errors on stderr (BC)
so `hg clone -q` or `hg pull -q` don't print `abort: no suitable
response from remote hg!` with no indication of what went wrong.
There are other errors still silenced by -q (like failing to push due
to a server hook), but the current change covers a good fraction of
the problem (all errors setting up the ssh connection, no such remote
repository, no access to the repository).

scmutil: speed up relativization of paths when it's a no-op
Running commands from the root is commmon, in particular for
automation. Running `hg files > /tmp/a` from the root of
mozilla-central on linux:
before:
real 0m1,510s
user 0m1,387s
sys 0m0,090s
after:
real 0m1,266s
user 0m1,165s
sys 0m0,073s
(there are 280k paths, so this was costing ~1us per path somehow)

context: implement mergestate() method
This will let us have the mergestate storage be controlled by the context. In
particular, for working contexts we should use the existing mergestate, but
for overlay contexts it's inappropriate to drop files in .hg/merge.
