wireproto: move wireproto capabilities computation in a subfunction
It will help people that need to add capabilities (in a more subtle was that
just adding some to the list) in multiple way:
1. This function returns a list, not a string. Making it easier to look at,
extend or alter the content.
2. The original capabilities function will be store in the dictionary of wire
protocol command. So extension that wrap this function also need to update
the dictionary entry.
Both wrapping and update of the dictionary entry are needed because the
`hello` wire protocol use the function itself. This is specifically sneaky for
extension writer as ssh use the `hello` command while http use the
`capabilities` command.
With this new `_capabilities` function there is one and only one obvious
place to wrap when needed.
Test changesets filtering during exchanges (some tests are still in
test-obsolete.t)
$ cat > obs.py << EOF
> import mercurial.obsolete
> mercurial.obsolete._enabled = True
> EOF
$ echo '[extensions]' >> $HGRCPATH
$ echo "obs=${TESTTMP}/obs.py" >> $HGRCPATH
Push does not corrupt remote
----------------------------
Create a DAG where a changeset reuses a revision from a file first used in an
extinct changeset.
$ hg init local
$ cd local
$ echo 'base' > base
$ hg commit -Am base
adding base
$ echo 'A' > A
$ hg commit -Am A
adding A
$ hg up 0
0 files updated, 0 files merged, 1 files removed, 0 files unresolved
$ hg revert -ar 1
adding A
$ hg commit -Am "A'"
created new head
$ hg log -G --template='{desc} {node}'

Push it. The bundle should not refer to the extinct changeset.

Adding a changeset going extinct locally
------------------------------------------
Pull a changeset that will immediatly goes extinct (because you already have a
marker to obsolete him)
