cinap_lenrek 28e9566dc5 spin: Update to most recent version. (thanks Ori_B)
from Ori_B:

There were a small number of changes needed from the tarball
on spinroot.org:

  - The mkfile needed to be updated
  - Memory.h needed to not be included
  - It needed to invoke /bin/cpp instead of gcc -E
  - It depended on `yychar`, which our yacc doesn't
    provide.

I'm still figuring out how to use spin, but it seems to do
the right thing when testing a few of the examples:

	% cd $home/src/Spin/Examples/
	% spin -a peterson.pml
	% pcc pan.c -D_POSIX_SOURCE
	% ./6.out

	(Spin Version 6.4.7 -- 19 August 2017)
		+ Partial Order Reduction

	Full statespace search for:
		never claim         	- (none specified)
		assertion violations	+
		acceptance   cycles 	- (not selected)
		invalid end states	+

	State-vector 32 byte, depth reached 24, errors: 0
	40 states, stored
	27 states, matched
	67 transitions (= stored+matched)
		0 atomic steps
	hash conflicts:         0 (resolved)

	Stats on memory usage (in Megabytes):
	0.002	equivalent memory usage for states (stored*(State-vector + overhead))
	0.292	actual memory usage for states
	128.000	memory used for hash table (-w24)
	0.534	memory used for DFS stack (-m10000)
	128.730	total actual memory usage


	unreached in proctype user
		/tmp/Spin/Examples/peterson.pml:20, state 10, "-end-"
		(1 of 10 states)

	pan: elapsed time 1.25 seconds
	pan: rate        32 states/second
