Subject: parser - fix memory leaks identified by valgrind tests

Browse Source 
This patch fixes a few memory leaks found by valgrind. Most of these
occur in error cases and as such, are not a big deal. The dbus TOK_MODE
and flags TOK_CONDID leaks in parser_yacc.y are legitimate leaks,
if of very small amounts of memory.
