catch urcu-paulmck.spin to my local version
The attached patch catches the repository up to my local version.
This adds the following:
o Checking for no-progress cycles.
o Allow enabling and disabling of update-side signal-mediated
broadcast memory barriers via #define statements.
o Enabling only those update-side signal-mediated broadcast
memory barriers that are required for correctness.
This version assumes that synchronize_rcu() is locally ordered, for
example, with smp_mb() calls between each pair of major statements.
Please note that smp_mb() is -not- assumed within the loops nor
immediately before the second counter flip.

sync_core to smp_mb transition
- move sync_core to smp_mb in urcu.c, update comments.
- cpuid clashes with -fPIC because it clobbers ebx. Use mb() if ___PIC__ is
defined.
