The options of git-fetch(1) which we pass to `parse_options()` are
declared globally in `builtin/fetch.c`. This means we're forced to use
global variables for all the options, which is more likely to cause
confusion than explicitly passing state around.
Refactor the code to move the options into `cmd_fetch()`. Move variables
that were previously forced to be declared globally and which are only
used by `cmd_fetch()` into function-local scope.

Parsing the display format happens inside of `display_state_init()`. As
we only need to check for a simple config entry, this is a natural
location to put this code as it means that display-state logic is neatly
contained in a single location.
We're about to introduce a new "porcelain" output format though that is
intended to be parseable by machines, for example inside of a script.
This format can be enabled by passing the `--porcelain` switch to
git-fetch(1). As a consequence, we'll have to add a second callsite that
influences the output format, which will become awkward to handle.
Refactor the code such that callers are expected to pass the display
format that is to be used into `display_state_init()`. This allows us to
lift up the code into the main function, where we can then hook it into
command line options parser in a follow-up commit.

We currently have two different display formats in git-fetch(1) with the
"full" and "compact" formats. This is tracked with a boolean value that
simply denotes whether the display format is supposed to be compacted
or not. This works reasonably well while there are only two formats, but
we're about to introduce another format that will make this a bit more
awkward to use.
Introduce a `enum display_format` that is more readily extensible.

When displaying reference updates, we try to print the references in a
neat table. As the table's width is determined its contents we thus need
to precalculate the overall width before we can start printing updated
references.
The calculation is driven by `display_state_init()`, which invokes
`refcol_width()` for every reference that is to be printed. This split
is somewhat confusing. For one, we filter references that shall be
attributed to the overall width in both places. And second, we
needlessly recalculate the maximum line length based on the terminal
columns and display format for every reference.
Refactor the code so that the complete width calculations are neatly
contained in `refcol_width()`.

`store_updated_refs()` parses the remote reference for two purposes:
- It gets used as a note when writing FETCH_HEAD.
- It is passed through to `display_ref_update()` to display
updated references in the following format:
```
* branch master -> master
```
In most cases, the parsed remote reference is the prettified reference
name and can thus be used for both cases. But if the remote reference is
HEAD, the parsed remote reference becomes empty. This is intended when
we write the FETCH_HEAD, where we skip writing the note in that case.
But when displaying the updated references this leads to inconsistent
output where the left-hand side of reference updates is missing in some
cases:
```
$ git fetch origin HEAD HEAD:explicit-head :implicit-head main
From https://github.com/git/git
* branch HEAD -> FETCH_HEAD
* [new ref] -> explicit-head
* [new ref] -> implicit-head
* branch main -> FETCH_HEAD
```
This behaviour has existed ever since the table-based output has been
introduced for git-fetch(1) via 165f390250 (git-fetch: more terse fetch
output, 2007-11-03) and was never explicitly documented either in the
commit message or in any of our tests. So while it may not be a bug per
se, it feels like a weird inconsistency and not like it was a concious
design decision.
The logic of how we compute the remote reference name that we ultimately
pass to `display_ref_update()` is not easy to follow. There are three
different cases here:
- When the remote reference name is "HEAD" we set the remote
reference name to the empty string. This is the case that causes
the left-hand side to go missing, where we would indeed want to
print "HEAD" instead of the empty string. This is what
`prettify_refname()` would return.
- When the remote reference name has a well-known prefix then we
strip this prefix. This matches what `prettify_refname()` does.
- Otherwise, we keep the fully qualified reference name. This also
matches what `prettify_refname()` does.
As the return value of `prettify_refname()` would do the correct thing
for us in all three cases, we can thus fix the inconsistency by passing
through the full remote reference name to `display_ref_update()`, which
learns to call `prettify_refname()`. At the same time, this also
simplifies the code a bit.
Note that this patch also changes formatting of the block that computes
the "kind" (which is the category like "branch" or "tag") and "what"
(which is the prettified reference name like "master" or "v1.0")
variables. This is done on purpose so that it is part of the diff,
hopefully making the change easier to comprehend.

When running `git fetch --no-recurse-submodules`, the exectation is that
we don't fetch any submodules. And while this works for fetches of a
single remote, it doesn't when fetching multiple remotes at once. The
result is that we do recurse into submodules even though the user has
explicitly asked us not to.
This is because while we pass on `--recurse-submodules={yes,on-demand}`
if specified by the user, we don't pass on `--no-recurse-submodules` to
the subprocess spawned to perform the submodule fetch.
Fix this by also forwarding this flag as expected.

To store the strategy options rebase prepends " --" to each one and
writes them to a file. To load them it reads the file and passes the
contents to split_cmdline(). This roughly mimics the behavior of the
scripted rebase but has a couple of limitations, (1) options containing
whitespace are not properly preserved (this is true of the scripted
rebase as well) and (2) options containing '"' or '\' are incorrectly
parsed and may cause the parser to return an error.
Fix these limitations by quoting each option when they are stored so
that they can be parsed correctly. Now that "--preserve-merges" no
longer exist this change also stops prepending "--" to the options when
they are stored as that was an artifact of the scripted rebase.
These changes are backwards compatible so the files written by an older
version of git can still be read. They are also forwards compatible,
the file can still be parsed by recent versions of git as they treat the
"--" prefix as optional.

When handling "--strategy-option" rebase collects the commands into a
struct string_list, then concatenates them into a string, prepending "--"
to each one before splitting the string and removing the "--" prefix.
This is an artifact of the scripted rebase and the need to support
"rebase --preserve-merges". Now that "--preserve-merges" no-longer
exists we can cleanup the way the argument is handled.
The tests for a bad strategy option are adjusted now that
parse_strategy_opts() is no-longer called when starting a rebase. The
fact that it only errors out when running "git rebase --continue" is a
mixed blessing but the next commit will fix the root cause of the
parsing problem so lets not worry about that here.

The sequencer stores the merge strategy options in an array of strings
which allocated with ALLOC_GROW(). Using "struct strvec" avoids manually
managing the memory of that array and simplifies the code.
Aside from memory allocation the changes to the sequencer are largely
mechanical, changing xopts_nr to xopts.nr and xopts[i] to xopts.v[i]. A
new option parsing macro OPT_STRVEC() is also added to collect the
strategy options. Hopefully this can be used to simplify the code in
builtin/merge.c in the future.
Note that there is a change of behavior to "git cherry-pick" and "git
revert" as passing “--no-strategy-option” will now clear any previous
strategy options whereas before this change it did nothing.

As discussed in t/README, tests should aim to use PERL_PATH rather than
straight "perl". We usually do this automatically with a "perl" function
in test-lib.sh, but a few cases need to be handled specially.
One such case is the apply-one-time-perl.sh CGI, which invokes plain
"perl". It should be using $PERL_PATH, but to make that work, we must
also instruct Apache to pass through the variable.
Prior to this patch, doing:
mv /usr/bin/perl /usr/bin/my-perl
make PERL_PATH=/usr/bin/my-perl test
would fail t5702, t5703, and t5616. After this it passes. This is a
pretty extreme case, as even if you install perl elsewhere, you'd likely
still have it in your $PATH. A more realistic case is that you don't
want to use the perl in your $PATH (because it's older, broken, etc) and
expect PERL_PATH to consistently override that (since that's what it's
documented to do). Removing it completely is just a convenient way of
completely breaking it for testing purposes.

When no merge.tool or diff.tool is configured or manually selected, the
selection of a default tool is sensitive to the DISPLAY variable; in a
GUI session a gui-specific tool will be proposed if found, and
otherwise a terminal-based one. This "GUI-optimizing" behavior is
important because a GUI can make a huge difference to a user's ability
to understand and correctly complete a non-trivial conflicting merge.
Some time ago the merge.guitool and diff.guitool config options were
introduced to enable users to configure both a GUI tool, and a non-GUI
tool (with fallback if no GUI tool configured), in the same environment.
Unfortunately, the --gui argument introduced to support the selection of
the guitool is still explicit. When using configured tools, there is no
equivalent of the no-tool-configured "propose a GUI tool if we are in a GUI
environment" behavior.
As proposed in <xmqqmtb8jsej.fsf@gitster.g>, introduce new configuration
options, difftool.guiDefault and mergetool.guiDefault, supporting a special
value "auto" which causes the corresponding tool or guitool to be selected
depending on the presence of a non-empty DISPLAY value. Also support "true"
to say "default to the guitool (unless --no-gui is passed on the
commandline)", and "false" as the previous default behavior when these new
configuration options are not specified.
