When we taught read_directory_recursive() to recurse into untracked
directories in search of ignored files given DIR_SHOW_IGNORED_TOO, that
had the side effect of teaching it to collect the untracked contents of
untracked directories. It doesn't always make sense to return these,
though (we do need them for `clean -d`), so we introduce a flag
(DIR_KEEP_UNTRACKED_CONTENTS) to control whether or not read_directory()
strips dir->entries of the untracked contents of untracked dirs.
We also introduce check_contains() to check if one dir_entry corresponds
to a path which contains the path corresponding to another dir_entry.
This also fixes known breakages in t7061, since status --ignored now
searches untracked directories for ignored files.

Per eb8c5b87, `status --ignored` by design does not list ignored files
if they are in a directory which contains only ignored and untracked
files (which is itself considered to be untracked) without `-uall`. This
does not make sense for `--ignored`, which claims to "Show ignored files
as well."
Thus we revisit eb8c5b87 and decide that for such directories, `status
--ignored` will list the directory as untracked *and* list all ignored
files within said directory even without `-uall`.

Some text editors like Notepad or LibreOffice write an UTF-8 BOM in
order to indicate that the file is Unicode text rather than whatever the
current locale would indicate.
If someone uses such an editor to edit a gitignore file, we are left
with those three bytes at the beginning of the file. If we do not skip
them, we will attempt to match a filename with the BOM as prefix, which
won't match the files the user is expecting.

The notion of "ignored tracked" directories introduced in 721ac4ed "dir.c:
Make git-status --ignored more consistent" has a few unwanted side effects:
- git-clean -d -X: deletes ignored tracked directories. git-clean should
never delete tracked content.
- git-ls-files --ignored --other --directory: lists ignored tracked
directories instead of "other" directories.
- git-status --ignored: lists ignored tracked directories while contained
files may be listed as modified. Paths listed by git-status should be
disjoint (except in long format where a path may be listed in both the
staged and unstaged section).
Additionally, the current behaviour violates documentation in gitignore(5)
("Specifies intentionally *untracked* files to ignore") and Documentation/
technical/api-directory-listing.txt ("DIR_SHOW_OTHER_DIRECTORIES: Include
a directory that is *not tracked*.").
In dir.c::treat_directory, remove the special handling of ignored tracked
directories, so that the DIR_SHOW_OTHER_DIRECTORIES flag only affects
"other" (i.e. untracked) directories. In dir.c::dir_add_name, check that
added paths are untracked even if DIR_SHOW_IGNORED is set.

'git-status --ignored path/' doesn't list ignored files and directories
within 'path' if some component of 'path' is classified as untracked.
Disable the DIR_SHOW_OTHER_DIRECTORIES flag while traversing leading
directories. This prevents treat_leading_path() with DIR_SHOW_IGNORED flag
from aborting at the top level untracked directory.
As a side effect, this also eliminates a recursive directory scan per
leading directory level, as treat_directory() can no longer call
read_directory_recursive() when called from treat_leading_path().

'git-status --ignored' lists empty untracked directories as ignored, even
though they don't have any ignored files.
When checking if a directory is already listed as untracked (i.e. shouldn't
be listed as ignored as well), don't assume that the directory has only
ignored files if it doesn't have untracked files, as the directory may be
empty.

'git-status --ignored' lists both the ignored directory and the ignored
files if the files are in a tracked sub directory.
When recursing into sub directories in read_directory_recursive, pass on
the check_only parameter so that we don't accidentally add the files.

Test all possible use-cases of git-status "--ignored" with the
"--untracked-files" option with values "normal" and "all":
- An untracked directory is listed as untracked if it has a mix of
untracked and ignored files in it. With -uall, ignored/untracked
files are listed as ignored/untracked.
- An untracked directory with only ignored files is listed as
ignored. With -uall, all files in the directory are listed.
- An ignored directory is listed as ignored. With -uall, all files
in the directory are listed as ignored.
- An ignored and committed directory is listed as ignored if it has
untracked files. With -uall, all untracked files in the
directory are listed as ignored.
