"git ls-files" can and does show multiple entries when the index is

"git diff" showed a submodule working tree with untracked cruft as
"Submodule commit <objectname>-dirty", but a natural expectation is
that the "-dirty" indicator would align with "git describe --dirty",
which does not consider having untracked files in the working tree
as source of dirtiness. The inconsistency has been fixed.
* sj/untracked-files-in-submodule-directory-is-not-dirty:
diff: do not show submodule with untracked files as "-dirty"

During a merge conflict, the name of a file may appear multiple
times in "git ls-files" output, once for each stage. If you use
both `--delete` and `--modify` at the same time, the output may
mention a deleted file twice.
When none of the '-t', '-u', or '-s' options is in use, these
duplicate entries do not add much value to the output.
Introduce a new '--deduplicate' option to suppress them.

Remove diagnostics that haven't been emitted by "fsck" or its
predecessors for around 15 years. This documentation was added in
c64b9b88605 (Reference documentation for the core git commands.,
2005-05-05), but was out-of-date quickly after that.
Notes on individual diagnostics:
- "expect dangling commits": Added in bcee6fd8e71 (Make 'fsck' able
to[...], 2005-04-13), documented in c64b9b88605. Not emitted since
1024932f019 (fsck-cache: walk the 'refs' directory[...],
2005-05-18).
- "missing sha1 directory": Added in 20222118ae4 (Add first cut at
"fsck-cache"[...], 2005-04-08), documented in c64b9b88605. Not
emitted since 230f13225df (Create object subdirectories on demand,
2005-10-08).

The end of the cache tree index extension format trails off with
ellipses ever since 23fcc98 (doc: technical details about the index
file format, 2011-03-01). While an intuitive reader could gather what
this means, it could be better to use "and so on" instead.
Really, this is only justified because I also wanted to point out that
the number of subtrees in the index format is used to determine when the
recursive depth-first-search stack should be "popped." This should help
to add clarity to the format.

I had difficulty in my efforts to learn about the cache tree extension
based on the documentation and code because I had an incorrect
assumption about how it behaved. This might be due to some ambiguity in
the documentation, so this change modifies the beginning of the cache
tree format by expanding the description of the feature.
My hope is that this documentation clarifies a few things:
1. There is an in-memory recursive tree structure that is constructed
from the extension data. This structure has a few differences, such
as where the name is stored.
2. What does it mean for an entry to be invalid?
3. When exactly are "new" trees created?

The index has a "cache tree" extension. This corresponds to a
significant API implemented in cache-tree.[ch]. However, there are a few
places that refer to this erroneously as "cached tree". These are rare,
but notably the index-format.txt file itself makes this error.
The only other reference is in t7104-reset-hard.sh.

While we currently have the `GIT_CONFIG_PARAMETERS` environment variable
which can be used to pass runtime configuration data to git processes,
it's an internal implementation detail and not supposed to be used by
end users.
Next to being for internal use only, this way of passing config entries
has a major downside: the config keys need to be parsed as they contain
both key and value in a single variable. As such, it is left to the user
to escape any potentially harmful characters in the value, which is
quite hard to do if values are controlled by a third party.
This commit thus adds a new way of adding config entries via the
environment which gets rid of this shortcoming. If the user passes the
`GIT_CONFIG_COUNT=$n` environment variable, Git will parse environment
variable pairs `GIT_CONFIG_KEY_$i` and `GIT_CONFIG_VALUE_$i` for each
`i` in `[0,n)`.
While the same can be achieved with `git -c <name>=<value>`, one may
wish to not do so for potentially sensitive information. E.g. if one
wants to set `http.extraHeader` to contain an authentication token,
doing so via `-c` would trivially leak those credentials via e.g. ps(1),
which typically also shows command arguments.

Add documentation and more tests for case-insensitivity. The existing
test only matched on the E-Mail part, but as shown here we also match
the name with strcasecmp().
This behavior was last discussed on the mailing list in the thread
starting at [1]. It seems we're keeping it like this, so let's
document it.

Change the mailmap documentation added in 0925ce4d49 (Add map_user()
and clear_mailmap() to mailmap, 2009-02-08) to continue discussing the
Jane/Joe example. I think this makes things a lot less confusing as
we're building up more complex examples using one set of data which
covers all the things we'd like to discuss.
Also add tests to assert that what our documentation says is what's
actually happening. This is mostly (or entirely) covered by existing
tests which I'm not deleting, but having these tests for the synopsis
makes it easier to follow-along while reading the tests & docs.
