Introduce filter_refs() which will act as an API for filtering
a set of refs. Based on the type of refs the user has requested,
we iterate through those refs and apply filters as per the
given ref_filter structure and finally store the filtered refs
in the ref_array structure.
Currently this will wrap around ref_filter_handler(). Hence,
ref_filter_handler is made file scope static.
As users of this API will no longer send a ref_filter_cbdata
structure directly, we make the elements of ref_filter_cbdata
pointers. We can now use the information given by the users
to obtain our own ref_filter_cbdata structure. Changes are made to
support the change in ref_filter_cbdata structure.

When we push to delete a reference for this repo, such as:

Allow the creation of a ref (e.g. stash) with a reflog already in

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

git-symbolic-ref or git-update-ref, rather than relying upon
git-checkout to do so, the "hack" for pacifying is_git_directory() with

Since the real HEAD is now populated with its proper final value, the

looks like an object ID is good enough to satisfy is_git_directory().
Therefore, just set the temporary HEAD to a literal value rather than
going through the effort of resolving the current branch's HEAD.

The caller of add_worktree() provides it with a command to invoke to
populate the new worktree. This was a useful abstraction during the
conversion of "git checkout --to" functionality to "git worktree add"
since git-checkout and git-worktree constructed the population command
differently. However, now that "git checkout --to" has been retired, and
add_worktree() has access to the options given to "worktree add", this
extra indirection is no longer useful and makes the code a bit
convoluted.
Moreover, the eventual goal is for git-worktree to make setting of HEAD
and worktree population distinct operations, whereas they are currently
conflated into a single git-checkout invocation. As such, add_worktree()
will eventually invoke other commands in addition to the worktree
population command, so it will be doing command construction itself
anyhow.
Therefore, relocate construction of the worktree population command from
add() to add_worktree().

Take advantage of 'struct child_process.env' to make it obvious that

We assign a local 'struct argv_array' to child_process.env, rather than

future patches will make add_worktree() invoke additional sub-commands,
and it's simpler to populate the environment array just once, whereas
child_process.env_array gets cleared after each invocation, thus would
require re-population for each sub-command.

die_if_checked_out() is intended to check if the branch about to be
checked out is already checked out either in the main worktree or in a
linked worktree. However, if .git/worktrees directory does not exist,
then it never bothers checking the main worktree, even though the
specified branch might indeed be checked out there, which is fragile
behavior.
This hasn't been a problem in practice since the current implementation
of "git worktree add" (and, earlier, "git checkout --to") always creates
.git/worktrees before die_if_checked_out() is called by the child "git
checkout" invocation which populates the new worktree.
However, git-worktree will eventually want to call die_if_checked_out()
itself rather than only doing so indirectly as a side-effect of invoking
git-checkout, and reliance upon order of operations (creating
.git/worktrees before checking if a branch is already checked out) is
fragile. As a general function, callers should not be expected to abide
by this undocumented and unwarranted restriction. Therefore, make
die_if_checked_out() more robust by checking the main worktree whether
.git/worktrees exists or not.
While here, also move a comment explaining why die_if_checked_out()'s
helper parses HEAD manually. Such information resides more naturally
with the helper itself rather than at its first point of call.
