dce-rpc: Test cases for unbounded state growth
dce-rpc: Handle smb2_close_request() in scripts
smb/dce-rpc: Cleanup DCE-RPC analyzers when fid is closed and limit them
dce-rpc: Do not repeatedly register removal hooks
(cherry picked from commit f9904511ab)
This adds previously-missing support for "Alter Context"
request/response PDUs (initial patch contributed by Mark Fernandez).
Also, context ID arguments were added to dce_rpc_bind, dce_rpc_request,
and dce_rpc_response in order to properly track what endpoint/operation
a given opnum maps to.
