feat: issue2551068 - Provide way to retrieve file/msg data via rest endpoint. Use Allow header to change format of /binary_content endpoint. If Allow header for endpoint is not application/json, it will be matched against the mime type for the file. */*, text/* are supported and will return the native mime type if present. Changes: move */* mime type from static dict of supported types. It was hardcoded to return json only. Now it can return a matching non-json mime type for the /binary_content endpoint. Edited some errors to explicitly add */* mime type. Cleanups to use ', ' separation in lists of valid mime types rather than just space separated. Remove ETag header when sending raw content. See issue 2551375 for background. Doc added to rest.txt. Small format fix up (add dash) in CHANGES.txt. Make passing an unset/None/False accept_mime_type to format_dispatch_output a 500 error. This used to be the fallback to produce a 406 error after all processing had happened. It should no longer be possible to take that code path as all 406 errors (with valid accept_mime_types) are generated before processing takes place. Make format_dispatch_output handle output other than json/xml so it can send back binary_content data. Removed a spurious client.response_code = 400 that seems to not be used. Tests added for all code paths. Database setup for tests msg and file entry. This required a file upload test to change so it doesn't look for file1 as the link returned by the upload. Download the link and verify the data rather than verifying the link. Multiple formatting changes to error messages to make all lists of valid mime types ', ' an not just space separated.

        Additional implementation notes for the Roundup Issue Tracker.
        Supplement for docstrings in the Roundup package.

====================
Implementation notes
====================

[see also the roundup package docstring]

There have been some modifications to the spec. I've marked these in the
source with 'XXX' comments when I remember to.

In short:
 Class.find() - may match multiple properties, uses keyword args.

 Class.filter() - isn't in the spec and it's very useful to have at the
    Class level.

 CGI interface index view specifier layout part - lose the '+' from the
    sorting arguments (it's a reserved URL character ;). Just made no
    prefix mean ascending and '-' prefix descending.

 ItemClass - renamed to IssueClass to better match it only having one
    hypderdb class "issue". Allowing > 1 hyperdb class breaks the
    "superseder" multilink (since it can only link to one thing, and
    we'd want bugs to link to support and vice-versa).

 template - the call="link()" is handled by special-case mechanisms in
    my top-level CGI handler. In a nutshell, the handler looks for a
    method on itself called 'index%s' or 'item%s' where %s is a class.
    Most items pass on to the templating mechanism, but the file class
    _always_ does downloading. It'll probably stay this way too...

 template - call="link(property)" may be used to link "the current item"
    (from an index) - the link text is the property specified.

 template - added functions that I found very useful: List, History and
    Submit.

 template - items must specify the message lists, history, etc. Having
    them by default was sometimes not wanted.

 template - index view determines its default columns from the
    template's ``tal:condition="request/show/<property>"`` directives.

 template - menu() and field() look awfully similar now .... ;)

 roundup_admin.py - the command-line tool has a lot more commands at its
    disposal
