wireproto: support for pullbundles
Pullbundles are similar to clonebundles, but served as normal inline
bundle streams. They are almost transparent to the client -- the only
visible effect is that the client might get less changes than what it
asked for, i.e. not all requested head revisions are provided.
The client announces support for the necessary retries with the
partial-pull capability. After receiving a partial bundle, it updates
the set of revisions shared with the server and drops all now-known
heads from the request list. It will then rerun getbundle until
no changes are received or all remote heads are present.
Extend badserverext to support per-socket limit, i.e. don't assume that
the same limits should be applied to all sockets.

#require killdaemons serve zstd
Client version is embedded in HTTP request and is effectively dynamic. Pin the
version so behavior is deterministic.

Also disable compression because zstd is optional and causes output to vary
and because debugging partial responses is hard when compression is involved

Failure to accept() socket should result in connection related error message
$ hg serve --config badserver.closebeforeaccept=true -p $HGPORT -d --pid-file=hg.pid
$ cat hg.pid > $DAEMON_PIDS
$ hg clone http://localhost:$HGPORT/ clone
abort: error: $ECONNRESET$
[255]
(The server exits on its own, but there is a race between that and starting a new server.
So ensure the process is dead.)
$ killdaemons.py $DAEMON_PIDS
Failure immediately after accept() should yield connection related error message
$ hg serve --config badserver.closeafteraccept=true -p $HGPORT -d --pid-file=hg.pid
$ cat hg.pid > $DAEMON_PIDS
TODO: this usually outputs good results, but sometimes emits abort:
error: '' on FreeBSD and OS X.
What we ideally want are:
abort: error: $ECONNRESET$
The flakiness in this output was observable easily with
--runs-per-test=20 on macOS 10.12 during the freeze for 4.2.
