[PATCH 8 of 8 V2] phase: use a binary phase part to push through bundle2 (BC)

We think that having this series in 4.4 release is quite important. We
added the new 'phases' bundle2 capability and associated pull support
in the 4.4 cycle. Not having push support in the same release (4.4)
means push support will not be covered by the new capability and we'll
have to distinct the two kinds of clients in the future. That is more
cumbersome to manage that we hoped when this series was written.
Also (but not directly related), we have a 14 patches series that
improves the bookmark exchange by using a binary part (resolving also
the old regression https://bz.mercurial-scm.org/show_bug.cgi?id=5165)
but it depends on this one.
I'm not sure we would have time to queue it, should I send it if this
one is queued?
