This re-adds "{foo WORD|bar WORD}" keyword-argument support to the CLI
parser.  Note that token graphs may now contain loops for this purpose;
therefore the matching functions retain a history of already-matched
tokens.  Each token can thus only be consumed once.

And then LINE... gets its special treatment with allowrepeat.

Now that we have keyword argument support in the matcher again, this
needs to be updated because argv[] will be 1:1 user input without
mangling or reordering.

This was SEGV'ing the test in bgp_master_init() since QOBJ_REG was used
without qobj_init() being called first.

exit 0 exits the entire testrunner... Oops.
Also, "unresolved" breaks too many things, so make this a pass.

PRIu64 is "u", we need "x", so PRIx64...

bison-2.7.x really wants "foo" for api.prefix while bison-3.0.x really
wants {foo} ... great.

This shuffles the code blocks in command_parser.y to match file output
order, then adjusts things to make the include handling less messy.

(also dropped unused DECIMAL_STRLEN_MAX define.)

This should hopefully fix the build on NetBSD 6.

bgp_master_init is called first thing in main(), so we need to wedge a
qobj_init() call in there...  this needs some improvement...

struct graph_node isn't quite the right place to control matcher
behaviour.

bison conditionally writes its output to different files based on the
filenames specified in the source code.  This could be disabled,
however...  flex changes its output filenames when "prefix" is
specified.  And ylwrap from <1.11 doesn't understand how to handle the
header file...

...so this requires automake 1.12 which can deal with this properly.
