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.

'git-status --ignored' still scans the work tree twice to collect
untracked and ignored files, respectively.
fill_directory / read_directory already supports collecting untracked and
ignored files in a single directory scan. However, the DIR_COLLECT_IGNORED
flag to enable this has some git-add specific side-effects (e.g. it
doesn't recurse into ignored directories, so listing ignored files with
--untracked=all doesn't work).
The DIR_SHOW_IGNORED flag doesn't list untracked files and returns ignored
files in dir_struct.entries[] (instead of dir_struct.ignored[] as
DIR_COLLECT_IGNORED). DIR_SHOW_IGNORED is used all throughout git.
We don't want to break the existing API, so lets introduce a new flag
DIR_SHOW_IGNORED_TOO that lists untracked as well as ignored files similar
to DIR_COLLECT_FILES, but will recurse into sub-directories based on the
other flags as DIR_SHOW_IGNORED does.
In dir.c::read_directory_recursive, add ignored files to either
dir_struct.entries[] or dir_struct.ignored[] based on the flags. Also move
the DIR_COLLECT_IGNORED case here so that filling result lists is in a
common place.
In wt-status.c::wt_status_collect_untracked, use the new flag and read
results from dir_struct.ignored[]. Remove the extra fill_directory call.
builtin/check-ignore.c doesn't call fill_directory, setting the git-add
specific DIR_COLLECT_IGNORED flag has no effect here. Remove for clarity.
Update API documentation to reflect the changes.
Performance: with this patch, 'git-status --ignored' is typically as fast
as 'git-status'.

Update documentation to change "GIT" which was a poor-man's small
caps to "Git". The latter was the intended spelling.
Also change "git" spelled in all-lowercase to "Git" when it refers
to the system as the whole or the concept it embodies, as opposed to
the command the end users would type.
* ta/doc-no-small-caps:
Documentation: StGit is the right spelling, not StGIT
Documentation: describe the "repository" in repository-layout
Documentation: add a description for 'gitfile' to glossary
Documentation: do not use undefined terms git-dir and git-file
Documentation: the name of the system is 'Git', not 'git'
Documentation: avoid poor-man's small caps GIT
By the end of a directory traversal, a dir_struct instance will
typically contains pointers to various data structures on the heap.
clear_directory() provides a convenient way to reclaim that memory.

Previously each exclude_list could potentially contain patterns
from multiple sources. For example dir->exclude_list[EXC_FILE]
would typically contain patterns from .git/info/exclude and
core.excludesfile, and dir->exclude_list[EXC_DIRS] could contain
patterns from multiple per-directory .gitignore files during
directory traversal (i.e. when dir->exclude_stack was more than
one item deep).
We split these composite exclude_lists up into three groups of
exclude_lists (EXC_CMDL / EXC_DIRS / EXC_FILE as before), so that each
exclude_list now contains patterns from a single source. This will
allow us to cleanly track the origin of each pattern simply by adding
a src field to struct exclude_list, rather than to struct exclude,
which would make memory management of the source string tricky in the
EXC_DIRS case where its contents are dynamically generated.
Similarly, by moving the filebuf member from struct exclude_stack to
struct exclude_list, it allows us to track and subsequently free
memory buffers allocated during the parsing of all exclude files,
rather than only tracking buffers allocated for files in the EXC_DIRS
group.

This adds index as a prerequisite for directory listing (with
exclude). At the moment directory listing is used by "git clean",
"git add", "git ls-files" and "git status"/"git commit" and
unpack_trees()-related commands. These commands have been
checked/modified to populate index before doing directory listing.
add_excludes_from_file() does not enable this feature, because it
is used to read .git/info/exclude and some explicit files specified
by "git ls-files".

Most of them are still stubs, but the procedure to build the HTML
documentation, maintaining the index and installing the end product are
there.
I placed names of people who are likely to know the most about the topic
in the stub files, so that volunteers will know whom to ask questions as
needed.
