using this option, namely copying instead of hardlinking,

`gc --auto` takes time and can block the user temporarily (but not any
less annoyingly). Make it run in background on systems that support
it. The only thing lost with running in background is printouts. But
gc output is not really interesting. You can keep it in foreground by
changing gc.autodetach.

In smart http, upload-pack adds new shallow lines at the beginning of
each rpc response. Only shallow lines from the first rpc call are
useful. After that they are thrown away. It's designed this way
because upload-pack is stateless and has no idea when its shallow
lines are helpful or not.
So after refs are negotiated with multi_ack_detailed and the server
thinks it learned enough, it sends "ACK obj-id ready", terminates the
rpc call and waits for the final rpc round. The client sends "done".
The server sends another response, which also has shallow lines at
the beginning, and the last "ACK obj-id" line.
When no-done is active, the last round is cut out, the server sends
"ACK obj-id ready" and "ACK obj-id" in the same rpc
response. fetch-pack is updated to recognize this and not send
"done". However it still tries to consume shallow lines, which are
never sent.
Update the code, make sure to skip consuming shallow lines when
no-done is enabled.

We set the default apache port for each of the httpd tests
to the 4-digit test number of the test script. We want these
to remain unique so that the tests do not conflict with each
other when run in parallel.
Instead of doing it manually in each test script, let's just
set it from the test name at run time. This is simpler, and
is one less thing to be updated when test scripts are
renamed (e.g., when being re-rolled or when conflicting
after being merged with another topic).
Incidentally, this fixes a case where t5537 and t5538 used
the same port number (5537), and could conflict with each
other when run in parallel.

Lasse Makholm noticed that running "git check-attr" from a place
totally unrelated to $GIT_DIR and $GIT_WORK_TREE does not give
expected results. I think it is because the command does not say it
wants to call setup_work_tree().
We still need to support use cases where only a bare repository is
involved, so unconditionally requiring a working tree would not work
well. Instead, make a call only in a non-bare repository.
We may want to see if we want to do a similar fix in the opposite
direction to check-ignore. The command unconditionally requires a
working tree, but it should be usable in a bare repository just like
check-attr attempts to be.

When a repo was fully repacked, and is repacked again, we may run
into the situation that "new" packfiles have the same name as
already existing ones (traditionally packfiles have been named after
the list of names of objects in them, so repacking all the objects
in a single pack would have produced a packfile with the same name).
The logic is to rename the existing ones into filename like
"old-XXX", create the new ones and then remove the "old-" ones.
When something went wrong in the middle, this sequence is rolled
back by renaming the "old-" files back.
The renaming into "old-" did not work as intended, because
file_exists() was done on "XXX", not "pack-XXX". Also when rolling
back the change, the code tried to rename "old-pack-XXX" but the
saved ones are named "old-XXX", so this couldn't have worked.

Besides, that

The prefix_path_gently() function currently applies real_path to
everything if given an absolute path, dereferencing symlinks both
outside and inside the work tree.
This causes most high-level functions to misbehave when acting on
symlinks given via absolute paths. For example
$ git add /dir/repo/symlink
attempts to add the target of the symlink rather than the symlink
itself, which is usually not what the user intends to do.
In order to manipulate symlinks in the work tree using absolute paths,
symlinks should only be dereferenced outside the work tree.
Modify the prefix_path_gently() to first normalize the path in order to
make sure path levels are separated by '/', then pass the result to
'abspath_part_inside_repo' to find the part inside the work tree
(without dereferencing any symlinks inside the work tree).
For absolute paths, prefix_path_gently() did not, nor does now do, any
actual prefixing, hence the result from abspath_part_in_repo() is
returned as-is.

In order to extract the part of an absolute path which lies inside the
repo, it is not possible to directly use real_path, since that would
dereference symlinks both outside and inside the work tree.
Add an abspath_part_inside_repo() function which first checks if the
work tree is already the prefix, then incrementally checks each path
level by temporarily NUL-terminating at each '/' and comparing against
the work tree path. If a match is found, it overwrites the input path
with the remainder past the work tree (which will be the part inside the
work tree).
This function is currently only intended for use in
'prefix_path_gently'.

One edge-case that isn't currently checked in the tests is the beginning
of the path matching the work tree, despite the target not actually
being the work tree, for example:
path = /dir/repoa
work_tree = /dir/repo
should fail since the path is outside the repo. However, if /dir/repoa
is in fact a symlink that points to /dir/repo, it should instead
succeed.
