5bc73de59d feat: move mblog header handling into mime4cl
Accessing the headers of a MIME message feels like something mime4cl
should handle. We implemented this ad hoc in mblog before in order to
not need to worry about doing it in a sensible way. Now we introduce a
decent-ish interface for getting a header from a MIME message,
mime-message-header-values:

* It returns a list because MIME message headers may appear multiple
  times.

* It decodes RFC2047 only upon request, as you may want to be stricter
  about parsing certain fields.

* It checks header name equality case insensitively.

The code for decoding the RFC2047 string is retained and still uses
babel for doing the actual decoding.

f83ef56141 refactor(3p/lisp/mime4cl): use trivial-gray-streams
This should be a net positive for portability and lets us drop some of
the CMUCL cruft (which we don't test anyway, CMU support may have
regressed regardless).

8f6955176f feat(3p/lisp/mime4cl): build using buildLisp
The following changes are required to make mime4cl build:

* file-position doesn't like to be called with NIL as the position
  argument, so we have to make sure to not do that in
  stream-file-position. My workaround is a bit clunky, but works.

* Tests discover the sample file via relative path resolution. This
  doesn't work when they are imported into the nix store as individual
  files. Instead we make use of the fact that DEFVAR is a no-op if the
  variable is already defined and inject a file via the nix build that
  sets the relevant ones. For the path to sample1.msg, we need to create
  a new variable.
