Add an err argument to log_ref_setup that can explain the reason
for a failure. This then eliminates the need to manage errno through
this function since we can just add strerror(errno) to the err string
when meaningful. No callers relied on errno from this function for
anything else than the error message.
Also add err arguments to private functions write_ref_to_lockfile,
log_ref_write_1, commit_ref_update. This again eliminates the need to
manage errno in these functions.
Some error messages are slightly reordered.
Update of a patch by Ronnie Sahlberg.

The safe_create_reflog function creates a reflog, if it does not
already exist.
The log_ref_setup function becomes private and gains a force_create
parameter to force the creation of a reflog even if log_all_ref_updates
is false or the refname is not one of the special refnames.
The new parameter also reduces the need to store, modify, and restore
the log_all_ref_updates global before reflog creation.
In a moment, we will use this to add reflog creation commands to
git-reflog.

This is necessary because alternate ref backends might store reflogs
somewhere other than .git/logs. Code that now directly manipulates
.git/logs should instead go through git-reflog.

Add a flag to allow forcing the creation of a reflog even if the ref
name and core.logAllRefUpdates setting would not ordinarily cause ref
creation.
In a moment, we will use this to add options to git tag and git
update-ref to force reflog creation.

Allow the creation of a ref (e.g. stash) with a reflog already in
place. For most refs (e.g. those under refs/heads), this happens
automatically, but for others, we need this option.
Currently, git does this by pre-creating the reflog, but alternate ref
backends might store reflogs somewhere other than .git/logs. Code
that now directly manipulates .git/logs should instead use git
plumbing commands.
I also added --create-reflog to git tag, just for completeness.
In a moment, we will use this argument to make git stash work with
alternate ref backends.
