Continuations of bullet list items must be indented by exactly 4
spaces (according to pandoc_markdown(5) on Debian jessie).
This is most easily achieved by making the bullet list items have two
spaces before the `*'.

This commits (more or less) this file to be processed with pandoc,
rather than other markdown processors. There is, unfortunately, no
widely-accepted way to declare a title for the document.
I tested feeding the document to markdown(1) on Debian jessie and it
reproduced the % line as if it were simple text. I guess many other
markdown processors will do something similarly tolerable. My
internet searches did not discover a markdown processor that used
lines starting with & for something else.

We are going to want to format SUPPORT.md which does not match the
filename patterns in docs/. So provide a way to make an ad-hoc rule
using pandoc with the standard options.
No functional change in this patch.

This utility reads json format pandoc output, from parsing one or more
SUPPORT.md files, and generates an HTML table element containing the
principal version and feature information.
This is rather hairier than I anticipated when I started out; hence
the 400-odd-line Perl script.
Machinery to assemble the appropriate inputs for parse-support-md
will be in the next commit.

This archaeology script:
- figures out what the current and previous Xen versions were
- looks for appropriate git branches for them
- finds SUPPORT.md for each one
- feeds its findings to parse-support-md
We do not intend to integrate this into docs/Makefile, because it
relies on the git history. Instead, we will take the rune provided in
the head comment and paste a variant of it into an appropriate cronjob
on xenbits.

+ <h1>Xen versions and features support matrix</h1>
+
+ This table summarises the support status of Xen releases,
+ and of individual features within each release.
+
+ <h2>Important notes</h2>
+
+ The matrix is extracted automatically
+ from the formal support status documents
+ in each Xen release.
+ The full formal support status document
+ is linked to from the column heading for each version.
+
+ <p>
+ The individual entries are summaries;
+ where a specific entry has more information in the full
+ document a link, denoted [*], is provided.
+ The statuses Supported, Experimental, and so on,
+ are likewise defined in the full document.
+
+ <p>
+ Sometimes the same feature, or a similar feature,
+ is named differently
+ in the documentation for different releases.
+ In such cases the table will show it as
+ two separate features,
+ with a discontinuity in support,
+ even though support may have been continuous.
+
+ <p>
+ The support status of versions earlier than listed here
+ is documented
+ <a href="https://wiki.xenproject.org/wiki/Xen_Project_Release_Features">on the wiki</a>.

+
+# Algorithm:
+#
+# We start with `refs/remotes/origin/master' and process its

+# Then we try to find the next previous revision. This is done by

+# the whole tree for the version in question.) Then we use git log on
+# xen/Makefile to try to find a commit where the version changed.
+# This gives us the previous version number, NN.
+#
+# That is substituted into the `refs/remotes/origin/stable-NN'
+# argument to get the tip of the relevant branch. That in turns
+# contains another SUPPORT.md. We keep going until either the ref
+# itself is missing, or we get to a ref with no SUPPORT.md.

There is also an accompanying SUPPORT.html to make the links for 4.11
work.
Patches 1-3 fix syntax trouble in SUPPORT.md (and commit us to using
pandoc format for it). Patches 4-7 arrange to generate a SUPPORT.html
at the toplevel of the generated docs. These should all be backported
to 4.10.
Patches 8 and 9 are the support matrix generator. They are not hooked
into any of the xen.git makefiles but it seemed best to have them here
in xen.git/docs rather than floating about in some ad hoc crontab
repo.

I think if the output is tolerably accurate, it would be valuable to
get this set up as a cron job ASAP. Stylistic and formatting
improvements etc. can be done on top.
My plan is that the cron job will use the matrix generator from
xen.git#master.
For my reference, this was generated with
docs/support-matrix-generate HEAD SUPPORT.html refs/heads/wip.support-stmt-NN https://xenbits.xen.org/docs/NN-testing/SUPPORT.html >t.html
rsync -vP t.html SUPPORT.html xenbits:public_html/2018/support-matrix-example-v1/

Ian, this looks good.
Only a small comment: for table entries such as
x86/PCI Device Passthrough x86 PV Supported, with caveats Supported, with caveats
x86 HVM Supported, with caveats[*] Supported, with caveats[*]
The footnote [*] should probably apply to all items in the tree, not just the last one. Also, the 4.10 link didn't work (probably because the SUPPORT.md format changes need backporting)
Regards
Lars
