Re: [DTC PATCH 2/2] Preserve scanner state when /include/ing.

So, like, the other day Scott Wood mumbled:

This allows /include/s to work when in non-default states,
such as PROPNODECHAR.

We may want to use state stacks to get rid of BEGIN_DEFAULT() altogether...

Hmmm..  With this applied, I get the usual warning:

        CHK version_gen.h
         CC dtc-lexer.lex.o
    dtc-lexer.lex.c:1901: warning: 'yy_top_state' defined but not used

*grumble*

Applied.
