[PATCH 4/6] remote.c: provide per-branch pushremote name
From: Jeff King <hidden>

When remote.c loads its config, it records the
branch.*.pushremote for the current branch along with the
global remote.pushDefault value, and then binds them into a
single value: the default push for the current branch. We
then pass this value (which may be NULL) to remote_get_1
when looking up a remote for push.
This has a few downsides:
1. It's confusing. The early-binding of the "current
value" led to bugs like the one fixed by 98b406f
(remote: handle pushremote config in any order,
2014-02-24). And the fact that pushremotes fall back to
ordinary remotes is not explicit at all; it happens
because remote_get_1 cannot tell the difference between
"we are not asking for the push remote" and "there is
no push remote configured".
2. It throws away intermediate data. After read_config()
finishes, we have no idea what the value of
remote.pushDefault was, because the string has been
overwritten by the current branch's
branch.*.pushremote.
3. It doesn't record other data. We don't note the
branch.*.pushremote value for anything but the current
branch.
Let's make this more like the fetch-remote config. We'll
record the pushremote for each branch, and then explicitly
compute the correct remote for the current branch at the
time of reading.
