[bug#44518] [PATCH v2 00/25] Add matterhorn package.

[Romain GARBAGE]

v2 changes:
* one commit per package addition/update
* matterhorn inputs sorted alphabetically
* ghc-crypton description modified to use Texinfo syntax
* ghc-crypton-x509 description modified
* added a comment explaining why tests are disabled for 
ghc-crypton-x509
* updated ghc-text-zipper instead of adding a new package with a more
up-to-date version
* removed cosmetic changes for unrelevant packages (added dby mistake)

A few comments regarding the other points raised by Ricardo:
* As for reenabling the tests for ghc-crypton-x509, the PR mentioned in
the comment provided a trivial fix of the .cabal file (which I didn't
try). I can add it as a snippet or a substitute* in a fix phase if
needed, just let me know.

* As for updating ghc-tls, ghc-vty and ghc-unix-compat, it seems that
the changes are not trivial and that updating these packages introduces
breakages (tested locally). IMHO, updating the corresponding
packages/fixing the breakages is out of the scope of this patch series.
What would the proper way to handle things here?
