wireproto: advertise supported media types and compression formats

This commit introduces support for advertising a server's support for
media types and compression formats in accordance with the spec defined
in internals.wireproto.

The bulk of the new code is a helper function in wireproto.py to
obtain a prioritized list of compression engines available to the
wire protocol. While not utilized yet, we implement support
for obtaining the list of compression engines advertised by the
client.

The upcoming HTTP protocol enhancements are a bit lower-level than
existing tests (most existing tests are command centric). So,
this commit establishes a new test file that will be appropriate
for holding tests around the functionality of the HTTP protocol
itself.

Rounding out this change, `hg debuginstall` now prints compression
engines available to the server.

Revert interactive tests
1 add and commit file f
2 add commit file folder1/g
3 add and commit file folder2/h
4 add and commit file folder1/i
5 commit change to file f
6 commit changes to files folder1/g folder2/h
7 commit changes to files folder1/g folder2/h
8 revert interactive to commit id 2 (line 3 above), check that folder1/i is removed and
9 make workdir match 7
10 run the same test than 8 from within folder1 and check same expectations

Check editing files newly added by a revert

1) Create a dummy editor changing 1 to 42
  $ cat > $TESTTMP/editor.sh << '__EOF__'
  > cat "$1"  | sed "s/1/42/g"  > tt
  > mv tt  "$1"
  > __EOF__

2) Add k
  $ printf "1\n" > k
  $ hg add k
  $ hg commit -m "add k"

3) Use interactive revert with editing (replacing +1 with +42):
  $ printf "0\n2\n" > k
  $ HGEDITOR="\"sh\" \"${TESTTMP}/editor.sh\"" hg revert -i  <<EOF
  > y
  > e
