transaction-summary: show the range of new revisions upon pull/unbundle (BC)

Upon pull or unbundle, we display a message with the range of new revisions
fetched. This revision range could readily be used after a pull to look out
what's new with 'hg log'. The algorithm takes care of filtering "obsolete"
revisions that might be present in transaction's "changes" but should not be
displayed to the end user.

compression formats are advertised in compression capability

  $ killdaemons.py

server.compressionengines can replace engines list wholesale

  $ hg serve --config server.compressionengines=none -R server -p $HGPORT -d --pid-file hg.pid
  $ cat hg.pid > $DAEMON_PIDS
  $ get-with-headers.py $LOCALIP:$HGPORT '?cmd=capabilities' | tr ' ' '\n' | grep '^compression=none$' > /dev/null

  $ killdaemons.py

Order of engines can also change

  $ hg serve --config server.compressionengines=none,zlib -R server -p $HGPORT -d --pid-file hg.pid
  $ cat hg.pid > $DAEMON_PIDS
  $ get-with-headers.py $LOCALIP:$HGPORT '?cmd=capabilities' | tr ' ' '\n' | grep '^compression=none,zlib$' > /dev/null

  $ killdaemons.py

Start a default server again

  $ hg serve -R server -p $HGPORT -d --pid-file hg.pid
  $ cat hg.pid > $DAEMON_PIDS

No Accept will send 0.1+zlib, even though "none" is preferred b/c "none" isn't supported on 0.1

Explicit 0.1 will send zlib because "none" isn't supported on 0.1

0.2 with no compression will get "none" because that is server's preference
(spec says ZL and UN are implicitly supported)
