This reverts 1495ff7da5 ("checkout: introduce checkout.overlayMode
config", 2019-01-08) and thus removes the checkout.overlayMode config
option.
The option was originally introduced to give users the option to make
the new no-overlay behaviour the default. However users may be using
'git checkout' in scripts, even though it is porcelain. Users setting
the option to false may actually end up accidentally breaking scripts.
With the introduction of a new subcommand that will make the behaviour
the default, the config option will not be needed anymore anyway.
Revert the commit and remove the config option, so we don't risk
breaking scripts.

In the previous patch we introduced a new no-overlay mode for git
checkout. Some users (such as the author of this commit) may want to
have this mode turned on by default as it matches their mental model
more closely. Make that possible by introducing a new config option
to that extend.

Currently 'git checkout' is defined as an overlay operation, which
means that if in 'git checkout <tree-ish> -- [<pathspec>]' we have an
entry in the index that matches <pathspec>, but that doesn't exist in
<tree-ish>, that entry will not be removed from the index or the
working tree.
Introduce a new --{,no-}overlay option, which allows using 'git
checkout' in non-overlay mode, thus removing files from the working
tree if they do not exist in <tree-ish> but match <pathspec>.
Note that 'git checkout -p <tree-ish> -- [<pathspec>]' already works
this way, so no changes are needed for the patch mode. We disallow
'git checkout --overlay -p' to avoid confusing users who would expect
to be able to force overlay mode in 'git checkout -p' this way.
Untracked files are not affected by this change, so 'git checkout
--no-overlay HEAD -- untracked' will not remove untracked from the
working tree. This is so e.g. 'git checkout --no-overlay HEAD -- dir/'
doesn't delete all untracked files in dir/, but rather just resets the
state of files that are known to git.

checkout: factor out mark_cache_entry_for_checkout function
Factor out the code that marks a cache entry as matched for checkout
into a separate function. We are going to introduce a new mode in
'git checkout' in a subsequent commit, that is going to have a
slightly different logic. This would make this code unnecessarily
complex.
Moving that complexity into separate functions will make the code in
the subsequent step easier to follow.

The key point for the if statement is that read_tree_some did not
update the entry, because either it doesn't exist in tree-ish or
doesn't match the pathspec. Clarify that.

read-cache: add invalidate parameter to remove_marked_cache_entries
When marking cache entries for removal, and later removing them all at
once using 'remove_marked_cache_entries()', cache entries currently
have to be invalidated manually in the cache tree and in the untracked
cache.
Add an invalidate flag to the function. With the flag set, the
function will take care of invalidating the path in the cache tree and
in the untracked cache.
Note that the current callsites already do the invalidation properly
in other places, so we're just passing 0 from there to keep the status
quo.
This will be useful in a subsequent commit.

entry: support CE_WT_REMOVE flag in checkout_entry
'checkout_entry()' currently only supports creating new entries in the
working tree, but not deleting them. Add the ability to remove
entries at the same time if the entry is marked with the CE_WT_REMOVE
flag.
Currently this doesn't have any effect, as the CE_WT_REMOVE flag is
only used in unpack-tree, however we will make use of this in a
subsequent step in the series.

The 'git worktree' command used to be just another mode in 'git
checkout', namely 'git checkout --to'. When the tests for the latter
were retrofitted for the former, the test name was adjusted, but the
test number was kept, even though the test is testing a different
command now. t/README states: "Second digit tells the particular
command we are testing.", so 'git worktree' should have a separate
number just for itself.
Move the worktree tests to t24* to adhere to that guideline. We're
going to make use of the free'd up numbers in a subsequent commit.

range-diff: always pass at least minimal diff options
Commit d8981c3f88 ("format-patch: do not let its diff-options affect
--range-diff", 2018-11-30) taught `show_range_diff()` to accept a
NULL-pointer as an indication that it should use its own "reasonable
default". That fixed a regression from a5170794 ("Merge branch
'ab/range-diff-no-patch'", 2018-11-18), but unfortunately it introduced
a regression of its own.
In particular, it means we forget the `file` member of the diff options,
so rather than placing a range-diff in the cover-letter, we write it to
stdout. In order to fix this, rewrite the two callers adjusted by d8981c3f88 to instead create a "dummy" set of diff options where they
only fill in the fields we absolutely require, such as output file and
color.
Modify and extend the existing tests to try and verify that the right
contents end up in the right place.
Don't revert `show_range_diff()`, i.e., let it keep accepting NULL.
Rather than removing what is dead code and figuring out it isn't
actually dead and we've broken 2.20, just leave it for now.

test framework has been updated to make a bug in the test script
(as opposed to bugs in Git that are discovered by running the
tests) stand out more prominently.
* sg/test-BUG:
tests: send "bug in the test script" errors to the script's stderr
The advice message to tell the user to migrate an existing graft
file to the replace system when a graft file was read was shown
even when "git replace --convert-graft-file" command, which is the
way the message suggests to use, was running, which made little
sense.
"git rebase --stat" to transplant a piece of history onto a totally
unrelated history were not working before and silently showed wrong
result. With the recent reimplementation in C, it started to instead
die with an error message, as the original logic was not prepared
to cope with this case. This has now been fixed.
* js/rebase-stat-unrelated-fix:
rebase --stat: fix when rebasing to an unrelated history
"git rebase" reimplemented recently in C accidentally changed the
way reflog entries are recorded (earlier "rebase -i" identified the
entries it leaves with "rebase -i", but the new version always
marks them with "rebase"). This has been corrected.
"git format-patch --range-diff" by mistake passed the diff options
used to generate the primary output of the command to the
range-diff machinery, which caused the range-diff in the cover
letter to include fairly useless "--stat" output. This has been
corrected by forcing a non-customizable default formatting options
on the range-diff machinery when driven by format-patch.
* jc/format-patch-range-diff-fix:
format-patch: do not let its diff-options affect --range-diff

rebase --stat: fix when rebasing to an unrelated history
When rebasing to a commit history that has no common commits with the
current branch, there is no merge base. In diffstat mode, this means
that we cannot compare to the merge base, but we have to compare to the
empty tree instead.
Also, if running in verbose diffstat mode, we should not output
Changes from <merge-base> to <onto>
as that does not make sense without any merge base.
Note: neither scripted nor built-in versoin of `git rebase` were
prepared for this situation well. We use this opportunity not only to
fix the bug(s), but also to make both versions' output consistent in
this instance. And add a regression test to keep this working in all
eternity.

The scripted version of "rebase" honored the `GIT_REFLOG_ACTION`,
and some automation scripts expected the reflog entries to be
prefixed with "rebase -i", not "rebase", after running "rebase -i".
This regressed in the reimplementation in C.
Fix that, and add a regression test, both with `GIT_REFLOG_ACTION`
set and unset.
Note: the reflog message for "rebase finished" did *not* honor
GIT_REFLOG_ACTION, and as we are very late in the v2.20.0-rcN phase,
we leave that bug for later (as it seems that that bug has been with
us from the very beginning).

format-patch: do not let its diff-options affect --range-diff
Stop leaking how the primary output of format-patch is customized to
the range-diff machinery and instead let the latter use its own
"reasonable default", in order to correct the breakage introduced by a5170794 ("Merge branch 'ab/range-diff-no-patch'", 2018-11-18) on
the 'master' front. "git format-patch --range-diff..." without any
weird diff option started to include the "range-diff --stat" output,
which is rather useless right now, that made the whole thing
unusable and this is probably the least disruptive way to whip the
codebase into a shippable shape.
We may want to later make the range-diff driven by format-patch more
configurable, but that would have to wait until we have a good
design.
git-reset.txt: render literal examples as monospace

git-reset.txt: render tables correctly under Asciidoctor
Asciidoctor removes the indentation of each line in these tables, so the
last lines of each table have a completely broken alignment.
Similar to 379805051d ("Documentation: render revisions correctly under
Asciidoctor", 2018-05-06), use an explicit literal block to indicate
that we want to keep the leading whitespace in the tables.
Because this gives us some extra indentation, we can remove the one that
we have been carrying explicitly. That is, drop the first six spaces of
indentation on each line. With Asciidoc (8.6.10), this results in
identical rendering before and after this commit, both for git-reset.1
and git-reset.html.

The advice to run 'git replace --convert-graft-file' added in f9f99b3f7d ("Deprecate support for .git/info/grafts", 2018-04-29)
didn't add an exception for the 'git replace --convert-graft-file'
codepath itself.
As a result we'd suggest running --convert-graft-file while the user
was running --convert-graft-file, which makes no sense. Before:
$ git replace --convert-graft-file
hint: Support for <GIT_DIR>/info/grafts is deprecated
hint: and will be removed in a future Git version.
hint:
hint: Please use "git replace --convert-graft-file"
hint: to convert the grafts into replace refs.
hint:
hint: Turn this message off by running
hint: "git config advice.graftFileDeprecated false"
Add a check for that case and skip printing the advice while the user
is busy following our advice.

Test scripts checking 'git daemon' stop the daemon with a TERM signal,
and the 'stop_git_daemon' helper checks the daemon's exit status to
make sure that it indeed died because of that signal.
This check is bogus since 03c39b3458 (t/lib-git-daemon: use
test_match_signal, 2016-06-24), for two reasons:
- Right after killing 'git daemon', 'stop_git_daemon' saves its exit
status in a variable, but since 03c39b3458 the condition checking
the exit status looks at '$?', which at this point is not the exit
status of 'git daemon', but that of the variable assignment, i.e.
it's always 0.
- The unexpected exit status should abort the whole test script with
'error', but it doesn't, because 03c39b3458 forgot to negate
'test_match_signal's exit status in the condition.
This patch fixes both issues.
