This also makes explicit (through the KNOWN_FAILURE_FORCED_SWITCH_TESTS

test_submodule_forced_switch() do not correctly handle the situation in
which a submodule is replaced with an ordinary directory.

A new option --ignore-cr-at-eol tells the diff machinery to treat a
carriage-return at the end of a (complete) line as if it does not
exist.
Just like other "--ignore-*" options to ignore various kinds of
whitespace differences, this will help reviewing the real changes
you made without getting distracted by spurious CRLF<->LF conversion
made by your editor program.

Since ff6f1f564 (submodule-config: lazy-load a repository's .gitmodules
file, 2017-08-03) rebase interactive fails if there are any submodules
with unstaged changes which have been configured with a value for
'submodule.<name>.ignore' in the repository's config.
This is due to how configured values of 'submodule.<name>.ignore' are
handled in addition to a change in how the submodule config is loaded.
When the diff machinery hits a submodule (gitlink as well as a
corresponding entry in the submodule subsystem) it will read the value
of 'submodule.<name>.ignore' stored in the repository's config and if
the config is present it will clear the 'IGNORE_SUBMODULES' (which is
the flag explicitly requested by rebase interactive),
'IGNORE_UNTRACKED_IN_SUBMODULES', and 'IGNORE_DIRTY_SUBMODULES' diff
flags and then set one of them based on the configured value.
Historically this wasn't a problem because the submodule subsystem
wasn't initialized because the .gitmodules file wasn't explicitly loaded
by the rebase interactive command. So when the diff machinery hit a
submodule it would skip over reading any configured values of
'submodule.<name>.ignore'.
In order to preserve the behavior of submodules being ignored by rebase
interactive, also set the 'OVERRIDE_SUBMODULE_CONFIG' diff flag when
submodules are requested to be ignored when checking for unstaged
changes.

These function help read and write capabilities.
To make them more generic and make it easy to reuse them,
the following changes are made:
- we don't require capabilities to come in a fixed order,
- we allow duplicates,
- we check that the remote supports the capabilities we
advertise,
- we don't check if the remote declares any capability we
don't know about.
The reason behind the last change is that the protocol
should work using only the capabilities that both ends
support, and it should not stop working if one end starts
to advertise a new capability.
Despite those changes, we can still require a set of
capabilities, and die if one of them is not supported.

Since edcc8581 ("convert: add filter.<driver>.process
option", 2016-10-16) when t0021/rot13-filter.pl was created, list
comparison in this perl script have been quite broken.
packet_txt_read() returns a 2-element list, and the right hand
side of "eq" also has a list with (two, elements), but "eq" takes
the last element of the list on each side, and compares them. The
first elements (0 or 1) on the right hand side lists do not matter,
which means we do not require to see a flush at the end of the
version -- a simple empty string or an EOF would do, which is
definitely not what we want.

The constants used for `ref_update::flags` were rather disorganized:
* The definitions in `refs.h` were not close to the functions that
used them.
* Maybe constants were defined in `refs-internal.h`, making them
visible to the whole refs module, when in fact they only made sense
for the files backend.
* Their documentation wasn't very consistent and partly still referred
to sha1s rather than oids.
* The numerical values followed no rational scheme
Fix all of these problems. The main functional improvement is that
some constants' visibility is now limited to `files-backend.c`.
