This adds yet another vimdiff/gvimdiff variant and presents conflicts as
a two-way diff between 'LOCAL' and 'REMOTE'. 'MERGED' is not opened
which deviates from the norm so usage text is echoed as a Vim message on
startup that instructs the user with how to proceed and how to abort.
Vimdiff is well-suited to two-way diffs so this is an option for a more
simple, more streamlined conflict resolution. For example: it is
difficult to communicate differences across more than two files using
only syntax highlighting; default vimdiff commands to get and put
changes between buffers do not need the user to manually specify
a source or destination buffer when only using two buffers.
Like other merge tools that directly compare 'LOCAL' with 'REMOTE', this
tool will benefit when paired with the new `mergetool.hideResolved`
setting.

The merge tools vimdiff2, vimdiff3, gvimdiff2, gvimdiff3 and bc3 are all
variants of the main tools vimdiff and bc. They are implemented in the
main and a one-liner script that just sources it exist for each.
Allow variants ending in [0-9] to be correctly wired without the need
for such one-liners, so instead of 5 scripts, only 1 (gvimdiff) is
needed.

Allow vimdiff users to signal that they do not want to use the
result of a merge by exiting with ":cquit", which tells Vim to
exit with an error code.
This is better than the current behavior because it allows users
to directly flag that the merge is bad, using a standard Vim
feature, rather than relying on a timestamp heuristic that is
unforgiving to users that save in-progress merge files.
The original behavior can be restored by configuring
mergetool.vimdiff.trustExitCode to false.

Built-in merge tools contain a hard-coded assumption about
whether or not a tool's exit code can be trusted to determine
the success or failure of a merge. Tools whose exit codes are
not trusted contain calls to check_unchanged() in their
merge_cmd() functions.
A problem with this is that the trustExitCode configuration is
not honored for built-in tools.
Teach built-in tools to honor the trustExitCode configuration.
Extend run_merge_cmd() so that it is responsible for calling
check_unchanged() when a tool's exit code cannot be trusted.
Remove check_unchanged() calls from scriptlets since they are no
longer responsible for calling it.
When no configuration is present, exit_code_trustable() is
checked to see whether the exit code should be trusted.
The default implementation returns false.
Tools whose exit codes can be trusted override
exit_code_trustable() to true.

When invoking default (g)vimdiff three-way merge, the merged file is
loaded as the first buffer but moved to the bottom as the fourth window.
This causes a disconnect between vim commands that operate on window
positions (e.g. CTRL-W_w) and those that operate on buffer index (e.g.
do/dp).
This change reorders the buffers to have the same index as windows while
keeping the cursor default to the merged result as the bottom window.

It's similar to the default, except that the other windows are hidden.
This ensures that removed/added colors are still visible on the main
merge window, but the other windows not visible.
Specially useful with merge.conflictstyle=diff3.

Remove the exceptions for "vim" and "defaults" in the mergetool library
so that every filename in mergetools/ matches 1:1 with the name of a
valid built-in tool.
Define the trivial fallback definition of shell functions in-line in
git-mergetool-lib script, instead of dot-sourcing them from another
file. The result is much easier to follow.
