Subject: add unlang_thread_instance()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=78f92d73a613def160a20ac3f3a07255d25d3bac;p=thirdparty%2Ffreeradius-server.git

add unlang_thread_instance()

which for now is only called from the "limit" keyword.

The thread instance data could arguably go into the stack frame,
but 99.9% of the stack frames won't use it.  So for now we just
make the users call it manually
