This commit introduces a rebase option `--quiet`. While `--quiet` is
commonly perceived as opposite to `--verbose`, this is not the case for
the rebase command: both `--quiet` and `--verbose` default to `false` if
neither `--quiet` nor `--verbose` is present.
Despite the default being `false` for both verbose and quiet mode,
passing the `--quiet` option will turn off verbose mode, and `--verbose`
will turn off quiet mode.
This patch introduces the `flags` bit field, with `REBASE_NO_QUIET`
as first user (with many more to come).
We do *not* use `REBASE_QUIET` here for an important reason: To keep the
implementation simple, this commit introduces `--no-quiet` instead of
`--quiet`, so that a single `OPT_NEGBIT()` can turn on quiet mode and
turn off verbose and diffstat mode at the same time. Likewise, the
companion commit which will introduce support for `--verbose` will have
a single `OPT_BIT()` that turns off quiet mode and turns on verbose and
diffstat mode at the same time.

This commit converts the equivalent part of the shell script
`git-legacy-rebase.sh` to run the pre-rebase hook (unless disabled), and
to interrupt the rebase with error if the hook fails.

This commit implements support for an --onto argument that is actually a
"symmetric range" i.e. `<rev1>...<rev2>`.
The equivalent shell script version of the code offers two different
error messages for the cases where there is no merge base vs more than
one merge base.
Though it would be nice to retain this distinction, dropping it makes it
possible to simply use the `get_oid_mb()` function. Besides, it happens
rarely in real-world scenarios.
Therefore, in the interest of keeping the code less complex, let's just
use that function, and live with an error message that does not
distinguish between those two error conditions.

The `--onto` option is important, as it allows to rebase a range of
commits onto a different base commit (which gave the command its odd
name: "rebase").
This commit introduces options parsing so that different options can
be added in future commits.
Note: As this commit introduces to the parse_options() call (which
"eats" argv[0]), the argc is now expected to be lower by one after this
patch, compared to before this patch: argv[0] no longer refers to the
command name, but to the first (non-option) command-line parameter.

This patch gives life to the skeleton added in the previous patches:
With this change, we can perform a elementary rebase (without any
options).
It can be tested thusly by:
git -c rebase.usebuiltin=true rebase HEAD~2
The rebase backends (i.e. the shell script functions defined in
`git-rebase--<backend>`) are still at work here and the "builtin
rebase"'s purpose is simply to parse the options and set
everything up so that those rebase backends can do their work.
Note: We take an alternative approach here which is *not* to set the
environment variables via `run_command_v_opt_cd_env()` because those
variables would then be visible by processes spawned from the rebase
backends. Instead, we work hard to set them in the shell script snippet.
On Windows, some of the tests fail merely due to core.fileMode not
being heeded that's why the core.*config variables is parsed here.
The `reset_head()` function is currently only used to detach the HEAD
to onto by way of starting the rebase, but it offers additional
functionality that subsequent patches will need like moving to the
original branch (possibly updating it) and also to do the equivalent of
`git reset --hard`.
The next commits will handle and support all the wonderful rebase
options.

This commit imitates the strategy that was used to convert the
difftool to a builtin. We start by renaming the shell script
`git-rebase.sh` to `git-legacy-rebase.sh` and introduce a
`builtin/rebase.c` that simply executes the shell script version,
unless the config setting `rebase.useBuiltin` is set to `true`.
The motivation behind this is to rewrite all the functionality of the
shell script version in the aforementioned `rebase.c`, one by one and
be able to conveniently test new features by configuring
`rebase.useBuiltin`.
In the original difftool conversion, if sane_execvp() that attempts to
run the legacy scripted version returned with non-negative status, the
command silently exited without doing anything with success, but
sane_execvp() should not return with non-negative status in the first
place, so we use die() to notice such an abnormal case.
We intentionally avoid reading the config directly to avoid
messing up the GIT_* environment variables when we need to fall back to
exec()ing the shell script. The test of builtin rebase can be done by
`git -c rebase.useBuiltin=true rebase ...`
