CHANGES and release notes for [GL #3935]

[func]		BIND now requires liburcu for lock-free data structures
		and concurrent safe memory reclamation. It replaces the
		home-grown lock-free linked list and QSBR machinery
		added in changes 6108 and 6109. The qp-trie code has
		been adjusted to use liburcu.
