As the comment of `repo_has_object_file()` and its `_with_flags()`
variant tells us, these functions are considered to be deprecated in
favor of `has_object()`. There are a couple of slight benefits in favor
of the replacement:
- The new function has a short-and-sweet name.
- More explicit defaults: `has_object()` doesn't fetch missing objects
via promisor remotes, and neither does it reload packfiles if an
object wasn't found by default. This ensures that it becomes
immediately obvious when a simple object existence check may result
in expensive actions.
Most importantly though, it is confusing that we have two sets of
functions that ultimately do the same thing, but with different
defaults.
Start sunsetting `repo_has_object_file()` and its `_with_flags()`
sibling by replacing all callsites with `has_object()`:
- `repo_has_object_file(...)` is equivalent to
`has_object(..., HAS_OBJECT_RECHECK_PACKED | HAS_OBJECT_FETCH_PROMISOR)`.
- `repo_has_object_file_with_flags(..., OBJECT_INFO_QUICK | OBJECT_INFO_SKIP_FETCH_OBJECT)`
is equivalent to `has_object(..., 0)`.
- `repo_has_object_file_with_flags(..., OBJECT_INFO_SKIP_FETCH_OBJECT)`
is equivalent to `has_object(..., HAS_OBJECT_RECHECK_PACKED)`.
- `repo_has_object_file_with_flags(..., OBJECT_INFO_QUICK)`
is equivalent to `has_object(..., HAS_OBJECT_FETCH_PROMISOR)`.
The replacements should be functionally equivalent.

Note that `git_path()` returned a string allocated via `get_pathname()`,
which uses a rotating set of statically allocated buffers. Consequently,
callers didn't have to free the returned string. The same isn't true for
`repo_common_path()`, so we also have to add logic to free the returned

Following the procedure we established to introduce breaking

$GIT_DIR/branches/ and $GIT_DIR/remotes/ directories to configure
remotes.

Back when Git was in its infancy, remotes were configured via separate
files in "branches/" (back in 2005). This mechanism was replaced later
that year with the "remotes/" directory. Both mechanisms have eventually
been replaced by config-based remotes, and it is very unlikely that
anybody still uses these directories to configure their remotes.
Both of these directories have been marked as deprecated, one in 2005
and the other one in 2011. Follow through with the deprecation and
finally announce the removal of these features in Git 3.0.

The refspec struct keeps two matched arrays: one for the refspec_item
structs and one for the original raw refspec strings. The main reason
for this is that there are other users of refspec_item that do not care
about the raw strings. But it does make managing the refspec struct
awkward, as we must keep the two arrays in sync. This has led to bugs in
the past (both leaks and double-frees).
Let's just store a copy of the raw refspec string directly in each
refspec_item struct. This simplifies the handling at a small cost:
1. Direct callers of refspec_item_init() will now get an extra copy of
the refspec string, even if they don't need it. This should be
negligible, as the struct is already allocating two strings for the
parsed src/dst values (and we tend to only do it sparingly anyway
for things like the TAG_REFSPEC literal).
2. Users of refspec_appendf() will now generate a temporary string,
copy it, and then free the result (versus handing off ownership of
the temporary string). We could get around this by having a "nodup"
variant of refspec_item_init(), but it doesn't seem worth the extra
complexity for something that is not remotely a hot code path.
Code which accesses refspec->raw now needs to look at refspec->item.raw.
Other callers which just use refspec_item directly can remain the same.
We'll free the allocated string in refspec_item_clear(), which they
should be calling anyway to free src/dst.
One subtle note: refspec_item_init() can return an error, in which case
we'll still have set its "raw" field. But that is also true of the "src"
and "dst" fields, so any caller which does not _clear() the failed item
is already potentially leaking. In practice most code just calls die()
on an error anyway, but you can see the exception in valid_fetch_refspec(),
which does correctly call _clear() even on error.

A refspec struct contains zero or more refspec_item structs, along with
matching "raw" strings. The items and raw strings are kept in separate
arrays, but those arrays will always have the same length (because we
write them only via refspec_append_nodup(), which grows both). This can
lead to bugs when manipulating the array, since the arrays and lengths
must be modified in lockstep. For example, the bug fixed in the previous
commit, which forgot to decrement raw_nr.
So let's get rid of "raw_nr" and have only "nr", making this kind of bug
impossible (and also making it clear that the two are always matched,
something that existing code already assumed but was not guaranteed by
the interface).
Even though we'd expect "alloc" and "raw_alloc" to likewise move in
lockstep, we still need to keep separate counts there if we want to
continue to use ALLOC_GROW() for both.
Conceptually this would all be simpler if refspec_item just held onto
its own raw string, and we had a single array. But there are callers
which use refspec_item outside of "struct refspec" (and so don't hold on
to a matching "raw" string at all), which we'd possibly need to adjust.
So let's not worry about refactoring that for now, and just get rid of
the redundant count variable. That is the first step on the road to
combining them anyway.

When we want to know the push urls for a remote, there is some simple
logic:
- if the user configured any remote.*.pushurl keys, then those make
the complete set of push urls
- otherwise we push to all urls in remote.*.url
Many spots implement this with a level of indirection, assigning to a
local url/url_nr pair. But since both arrays are now strvecs, we can
just use a pointer to select the appropriate strvec, shortening the code
a bit.
Even though this is now a one-liner, since it is application logic that
is present in so many places, it's worth abstracting a helper function.
In fact, we already have such a function, but it's local to
builtin/push.c. So we'll just make it available everywhere via remote.h.
There are two spots to pay special attention to here:
1. in builtin/remote.c's get_url(), we are selecting first based on
push_mode and then falling back to "url" when we're in push_mode
but no pushurl is defined. The updated code makes that much more
clear, compared to the original which had an "else" fall-through.
2. likewise in that file's set_url(), we _only_ respect push_mode,
sine the point is that we are adding to pushurl in that case
(whether it is empty or not). And thus it does not use our helper
function.

Now that the url/pushurl fields of "struct remote" own their strings, we
can switch from bare arrays to strvecs. This has a few advantages:
- push/clear are now one-liners
- likewise the free+assigns in alias_all_urls() can use
strvec_replace()
- we now use size_t for storage, avoiding possible overflow
- this will enable some further cleanups in future patches
There's quite a bit of fallout in the code that reads these fields, as
it tends to access these arrays directly. But it's mostly a mechanical
replacement of "url_nr" with "url.nr", and "url[i]" with "url.v[i]",
with a few variations (e.g. "*url" could become "*url.v", but I used
"url.v[0]" for consistency).

In `get_head_names()`, we assign the "refs/heads/*" string constant to
`struct refspec_item::{src,dst}`, which are both non-constant pointers.
Ideally, we'd refactor the code such that both of these fields were
constant. But `struct refspec_item` is used for two different usecases
with conflicting requirements:
- To query for a source or destination based on the given refspec. The
caller either sets `src` or `dst` as the branch that we want to
search for, and the respective other field gets populated. The
fields should be constant when being used as a query parameter,
which is owned by the caller, and non-constant when being used as an
out parameter, which is owned by the refspec item. This is is
contradictory in itself already.
- To store refspec items with their respective source and destination
branches, in which case both fields should be owned by the struct.
Ideally, we'd split up this interface to clearly separate between
querying and storing, which would enable us to clarify lifetimes of the
strings. This would be a much bigger undertaking though.
Instead, accept the status quo for now and cast away the constness of
the source and destination patterns. We know that those are not being
written to or freed, so while this is ugly it certainly is fine for now.

Apply the rules that rewrite callers of "refs" interfaces to explicitly
pass `struct ref_store`. The resulting patch has been applied with the
`--whitespace=fix` option.

Command line parser fix, and a small parse-options API update.
* jc/parse-options-short-help:
short help: allow a gap smaller than USAGE_GAP
remote: simplify "remote add --tags" help text
short help: allow multi-line opthelp
The help text for the --tags option was split into two option[]
entries, which was a hacky way to give two lines of help text (the
second entry did not have either short or long help, and there was
no way to invoke its entry---it was there only for the help text).
As we now support multi-line text in the option help, let's make
the second line of the help a proper second line and remove the
hacky second entry.

Reduce reliance on a global state in the config reading API.
* gc/config-context:
config: pass source to config_parser_event_fn_t
config: add kvi.path, use it to evaluate includes
config.c: remove config_reader from configsets
config: pass kvi to die_bad_number()
trace2: plumb config kvi
config.c: pass ctx with CLI config
config: pass ctx with config files
config.c: pass ctx in configsets
config: add ctx arg to config_fn_t
urlmatch.h: use config_fn_t type
config: inline git_color_default_config
Pass config_context to config callbacks in configset_iter(), trivially
setting the .kvi member to the cached key_value_info. Then, in config
callbacks that are only used with configsets, use the .kvi member to
replace calls to current_config_*(), and delete current_config_line()
because it has no remaining callers.
This leaves builtin/config.c and config.c as the only remaining users of
current_config_*().
