Warner Losh 52baf267be Update to latest git version of dtc to get new dtsv2 support,
including the include directive.

Fix minor build issue corrected by converting yypush_buffer_state and
yypop_buffer_state to yy_set_buffer_state and a hard-coded 100-deep
stack.  It was easier to fix it here than to import that support into
our flex.

The new tools and test hardness remain unsupported at the moment.
