Subject: [RELEASE] Userspace RCU 0.9.3

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 multiple
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 mainly a bugfix release, with noteworthy changes:
- Adds GNU Hurd support,
- Bumps the library current version and age because we added missing
  destroy functions for queues and stacks,
- Quite a few MacOS X support fixes.
