git/peek-remote.c
Johannes Sixt 98158e9cfd Change git_connect() to return a struct child_process instead of a pid_t.
This prepares the API of git_connect() and finish_connect() to operate on
a struct child_process. Currently, we just use that object as a placeholder
for the pid that we used to return. A follow-up patch will change the
implementation of git_connect() and finish_connect() to make full use
of the object.

Old code had early-return-on-error checks at the calling sites of
git_connect(), but since git_connect() dies on errors anyway, these checks
were removed.

[sp: Corrected style nit of "conn == NULL" to "!conn"]
