Behind END_TKN, there is another graph node whose data pointer is
actually struct cmd_element instead of struct cmd_token. Don't try to
interpret that as cmd_token. This causes very interesting crashes when
ASLR decides to give one of the strings of a command definition a lower
32-bit value that is a valid cmd_token_type (e.g. FORK_TKN).

A {foo|bar|baz} graph node will have more than 1/2 incoming links even
if no other references are left to it (which is what the assert was
previously trying to ensure.)
I don't see a good way to "fix" the assert so I'm just removing it.

The label initializer & nhrpd variable are just to shut up GCC 7,
the other two are actual bugs.

MTYPE_CMD_TOKEN_DATA isn't used anymore, I forgot to ditch the line.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

Fills token->varname based on context. WORD tokens use the WORD - if it
isn't actually "WORD". Other than that, a preceding constant token is
used as name.

Put core CLI graph stuff in lib/command_graph.[ch] and consistently
prefix all function names with "cmd_".
