[PATCH] gnu: Add argtable.

[Ricardo Wurmus]

Hi Guix,

attached is a patch to add argtable.  Ultimately, the "popt" module
should probably be renamed to something like "optparsers", but since
finding good names is something I'm not good at, I'll leave that to
someone else :)

~~ Ricardo

+source code as an array of argtable structs.  The command line is then parsed
+according to that specification and the resulting values are returned in those
+same structs where they are accessible to the main program.  Both tagged (-v,
+--verbose, --foo=bar) and untagged arguments are supported, as are multiple
+instances of each argument.  Syntax error handling is automatic and the library
+also provides the means for generating a textual description of the command
+line syntax.")
