    forge: refactor to allow multiple calls
    
     – permit extraction of multiple archives in a single specfile
       – %forgemeta, %forgesetup, %forgeautosetup: add a “-z <number>” switch to
         select a specific set of rpm variables
         (for example forgeurl<number> and version<number>)
       – %forgemeta, %forgesetup: add a “-a” switch to process all sets in one go
         (makes no sense in forgeautosetup, as you need so select specific patches)
       – %forgemeta: deprecate the “-u” switch, use “-z” it’s better
         (“-u” was awkward and mainly used by the %gometa macro. %gometa will now
          call the lua code directly)
     – %forgesetup: use “-v” for verbose processing, be quiet by default, drop “-q”
       (align with %forgemeta, %forgeautosetup and %autosetup)
     – %forgesetup, %forgeautosetup: only pass flags that make sense to
       %setup/%autosetup; reorder to match what works in el7
     – factor out complex or common lua code in separate lua modules, to allow:
       – code reuse in other macros without cut and pasting
       – direct lua routine invocation from other macros without going through a
         rpm macro
       – rpm syntax errors that point to a line in an actual lua file
     – %forgemeta: refactor the logic to drop as much forge-specific code as
       possible, use a single logic flow with tables of constants
     – %forgemeta: export more computed info in rpm variables, such as the
       %{_builddir} subdirectory an archive was extracted to (lifesaver when
       processing multiple archives)
     – %forgemeta: prepend secondary distprefixes with .S, to make clear they do
        not apply to the main archive
     – %forgemeta: add versionx to secondary distprefixes, if relevant
     – %forgemeta: make tar.bz2 the default archive format
    
    Caveats:
     – forge services implement full-release downloads via tags. However the actual
       syntax of such tags is not standardised. If the macro does not guess the
       correct tag an upstream uses for a specific release, you will need to
       set the tag value explicitly.
     – GitHub lets upstreams move their projects to new URLs, keeping the old URL
       active. It all works transparently *except* the top directory inside
       generated archives always matches the new project name (even when accessed
       by compatibility URLs, and even for releases that antedate the renaming).
       Therefore, if macro processing of a GitHub archive suddenly fails, start by
       checking if upstream didn’t rename itself.
    
    Multicall usage example (with “-a”)
     – to process a specific bloc in one of the macros use “-z <suffix>”
     – suffix 0 and no suffix are synonyms
     – therefore, calling the macros without “-a” or “-z” just works for the
       general use case when you have a single archive to process
     – caveat: forge services implement full-release
