The name-hash subsystem that is used to cope with case insensitive

cases for all the paths in the index by holding a pointer to a

If we're on a detached HEAD then wt_shortstatus_print_tracking() takes
the string "HEAD (no branch)", translates it, skips the first eleven
characters and passes the result to branch_get(), which returns a bogus
result and accesses memory out of bounds in order to produce it.
Somehow stat_tracking_info(), which is passed that result, does the
right thing anyway, i.e. it finds that there is no base.
Avoid the bogus results and memory accesses by checking for HEAD first
and exiting early in that case. This fixes t7060 with --valgrind.

Git-merge-file is documented to return one of three exit
codes:
- zero means the merge was successful
- a negative number means an error occurred
- a positive number indicates the number of conflicts
Unfortunately, this all gets stuffed into an 8-bit return
code. Which means that if you have 256 conflicts, this wraps
to zero, and the merge appears to succeed (and commits a
blob full of conflict-marker cruft!).
This patch clamps the return value to a maximum of 127,
which we should be able to safely represent everywhere. This
also leaves 128-255 for other values. Shells (and some parts
of git) will typically represent signal death as 128 plus
the signal number. And negative values are typically coerced
to an 8-bit unsigned value (so "return -1" ends up as 255).
Technically negative returns have the same problem (e.g.,
"-256" wraps back to 0), but this is not a problem in
practice, as the only negative value we use is "-1".

Editors on Windows can and do save text files with CRLF line
endings, which is the convention on the platform. We are seeing
reports that the "read" command in a port of bash to the environment
however does not strip the CRLF at the end, not adjusting for the
same convention on the platform.
This breaks the recently added sanity checks for the insn sheet fed
to "rebase -i"; instead of an empty line (hence nothing in $command),
the script was getting a lone CR in there.
Special case a lone CR and treat it the same way as an empty line to
work this around.
This patch (also) passes the test with Git for Windows, where the
issue was seen first.

The add_submodule_odb function tries to add a submodule's
object store as an "alternate". It needs the existing list
to be initialized (from the objects/info/alternates file)
for two reasons:
1. We look for duplicates with the existing alternate
stores, but obviously this doesn't work if we haven't
loaded any yet.
2. We link our new entry into the list by prepending it to
alt_odb_list. But we do _not_ modify alt_odb_tail.
This variable starts as NULL, and is a signal to the
alt_odb code that the list has not yet been
initialized.
We then call read_info_alternates on the submodule (to
recursively load its alternates), which will try to
append to that tail, assuming it has been initialized.
This causes us to segfault if it is NULL.
This rarely comes up in practice, because we will have
initialized the alt_odb any time we do an object lookup. So
you can trigger this only when:
- you try to access a submodule (e.g., a diff with
diff.submodule=log)
- the access happens before any other object has been
accessed (e.g., because the diff is between the working
tree and the index)
- the submodule contains an alternates file (so we try to
add an entry to the NULL alt_odb_tail)
To fix this, we just need to call prepare_alt_odb at the
start of the function (and if we have already initialized,
it is a noop).
Note that we can remove the prepare_alt_odb call from the
end. It is guaranteed to be a noop, since we will have
called it earlier.

If one side deletes a file and the other changes its
content, we notice and report a conflict. However, if
instead of changing the content, we change only the mode,
the merge does not notice (and the mode change is silently
dropped).
The trivial index merge notices the problem and correctly
leaves the conflict in the index, but both merge-recursive
and merge-one-file will silently resolve this in favor of
the deletion. In many cases that is a sane resolution, but
we should be punting to the user whenever there is any
question. So let's detect and treat this as a conflict (in
both strategies).

This script tests the filemode handling of merge-recursive,
but we do not test the same thing for merge-resolve. Let's
generalize the script a little:
1. Break out the setup steps for each test into a separate
snippet.
2. For each test, run it twice; once with "-s recursive"
and once with "-s resolve". We can avoid repeating
ourselves by adding a function.
3. Since we have a nice abstracted function, we can make
our tests more thorough by testing both directions
(change on "ours" versus "theirs").
This improves our test coverage, and will make this the
place to add more tests related to merging mode changes.
