push: restrict common discovery to the pushed set
This changeset make use of the ability of the set discovery to only search
common changeset for a subset of the repository. Restricting that search to the
pushed set avoid potential waste of time finding out the status of many
unrelated related revision.
Repository with many heads were especially badly affected by this. Here is an
example of findcommonhead discovery for pushing 11 outgoing changeset on a
repository with tens of thousand of unrelated heads. (discovery run over a ssh
link to localhost).
Before:
queries: 92
time: 44.1996s
After:
queries: 3
time: 0.6938s
A x63 speedup even with a network link without latency.
