branch: correctly reject refs/heads/{-dash,HEAD}

strbuf_check_branch_ref() is the central place where many codepaths
see if a proposed name is suitable for the name of a branch.  It was
designed to allow us to get stricter than the check_refname_format()
check used for refnames in general, and we already use it to reject
a branch whose name begins with a '-'.  The function gets a strbuf
and a string "name", and returns non-zero if the name is not
appropriate as the name for a branch.  When the name is good, it
places the full refname for the branch with the proposed name in the
strbuf before it returns.

However, it turns out that one caller looks at what is in the strbuf
even when the function returns an error.  Make the function populate
the strbuf even when it returns an error.  That way, when "-dash" is
given as name, "refs/heads/-dash" is placed in the strbuf when
returning an error to copy_or_rename_branch(), which notices that
the user is trying to recover with "git branch -m -- -dash dash" to
rename "-dash" to "dash".

While at it, use the same mechanism to also reject "HEAD" as a

example of good practices to follow, including logical, independent
commits; patch sign-offs; and sending patches to a mailing list.
Currently, people who want to cite a particular section tend to either
refer to it by name and let the interested party search through the
document to find it, or link to a given line number on GitHub and hope
the file doesn't change.

Instead, convert the document to AsciiDoc.  Build it as part of the
technical documentation, since it is likely of interest to the same
group of people.  Provide stable links to the sections which outside
parties are likely to want to link to.  Make some minor structural
changes to organize it so that it can be formatted sanely.

Since the makefile needs a .txt extension in order to build with the
rest of the documentation, simply copy the file.  Ignore the temporary
file so it doesn't get checked in accidentally, and remove it as part of
the clean process.  Do this instead of renaming the file so that people
who have already linked to the documentation (who we're trying to help)
don't find their links broken.  Avoid symlinking since Windows will not
like that.

This allows us to render the document as part of the website for the
benefit of others who wish to link to it as well as providing a more
nicely formatted display for our community and potential contributors.

Rewrite the loops so that we keep the original pointers, then call

1) Use `UNLEAK(result)` before the loop. Simple change, but not very

2) Use `pop_commit()` when looping. Slightly less simple change, but it

3) As in this patch, but with `UNLEAK()` instead of freeing. We'd still

super-obvious that we're about to exit, let's just free the lists -- it
probably doesn't affect the runtime much.

In `handle_independent()` we can drop `result` while we're here and
reuse the `revs`-variable instead. That matches several other users of

"canonical" field for the main namespace, although there is a "*"
field that is set to "" (empty). So in theory, we could specify the
empty namespace to get the main namespace, but that would make
specifying namespaces harder for the user: we would need to teach
users about the "empty" default namespace. It would also make the code
more complicated: we'd need to parse quotes in the configuration.

wt-status: actually ignore submodules when requested

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.
