266b18273a refs: add ref_type function
Add a function ref_type, which categorizes refs as per-worktree,
pseudoref, or normal ref.

Later, we will use this in refs.c to treat pseudorefs specially.
Alternate ref backends may use it to treat both pseudorefs and
per-worktree refs differently.

2036cb98d0 refs: introduce pseudoref and per-worktree ref concepts
Add glossary entries for both concepts.

Pseudorefs and per-worktree refs do not yet have special handling,
because the files refs backend already handles them correctly.  Later,
we will make the LMDB backend call out to the files backend to handle
per-worktree refs.

89dea97334 git-stash: use update-ref --create-reflog instead of creating files
This is in support of alternate ref backends which don't necessarily
store reflogs as files.

144c76fa39 update-ref and tag: add --create-reflog arg
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.

0f2a71d992 refs: add REF_FORCE_CREATE_REFLOG flag
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.

abd0cd3a30 refs: new public ref function: safe_create_reflog
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.

a4c653dfcd refs.c: add err arguments to reflog functions
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.

e2c6f7cd5a Fix definition of ARRAY_SIZE for non-gcc builds
The improved ARRAY_SIZE macro uses BARF_UNLESS_AN_ARRAY which expands
to a valid check for recent gcc versions and to 0 for older gcc
versions but is not defined on non-gcc builds.

Non-gcc builds need this macro to expand to 0 as well. The current outer
test (defined(__GNUC__) && (__GNUC__ >= 3)) is a strictly weaker
condition than the inner test (GIT_GNUC_PREREQ(3, 1)) so we can omit the
outer test and cause the BARF_UNLESS_AN_ARRAY macro to be defined
correctly on non-gcc builds as well as gcc builds with older versions.
