- We already have good custodian documentation for patchwork, add a
  reference and then link to it here.
- Add a reference to the existing b4 documentation, and reference it
  here.
- Note and link to patchwork integration, am/shazam and ty features of
  b4 as these are the most likely useful portions. Be specific about
  keeping the default ${summary} as that includes important information.

Although it has historically been different, the current standard
spelling of the neutral singular possessive pronoun is "its".

We shouldn't have had the link to our git tree be contained within "``"
as that meant that it did not work as a link, so remove those. And
rather than make this a link plus text, keep this as a link within the
text for overall clarity.

The previous wording on the paragraph about what branch to use when
submitting patches did not reflect how / when the next branch is
currently used. Reword this to note that master should be used for bug
and regression fixes, always, and that next should be used once it
opens, with -rc2.

The "Sending patches" and "Patman patch manager" documents refer to the
three-dash, "---", that separates patch parts. The symbol is written in
the documentation in the same form as it is in actual patches: as three
U+002D HYPHEN-MINUS characters. When building the documentation, Sphinx
converts this symbol to a U+2014 EM DASH, that is invalid in this case.

Make the three-dash symbol a reStructuredText inline literal to prevent
its conversion; that is, enclose it in a pair of double backquotes (`).

This is a common typo listed in scripts/spelling.txt. Fix it to match the
patchwork status, which is superseded.

Import as-is much of the old "Patches" wiki page to the current
sending_patches.rst file. This means we need to move patman to being
included in the higher level ToC and add a reference for "Custodians" in
the process document. A very minimal amount of content changing and
rewording is done here as part of the import, in order to make the
conversion easier.
