Subject: [RELEASE] Userspace RCU 0.7.3

liburcu is a LGPLv2.1 userspace RCU (read-copy-update) library. This
data synchronization library provides read-side access which scales
linearly with the number of cores. It does so by allowing multiples
copies of a given data structure to live at the same time, and by
monitoring the data structure accesses to detect grace periods after
which memory reclamation is possible.

liburcu-cds provides efficient data structures based on RCU and
lock-free algorithms. Those structures include hash tables, queues,
stacks, and doubly-linked lists.

This is a minor compatibility-related release, fixing build issues with
FreeBSD and NetBSD. On Linux, only the test_perthreadlock fix could
change the result of make check (which could previously fail due to
non-initialized mutexes), but it does not impact anything installed on
the system.

Changelog:
