urcu-qsbr: avoid useless futex wakeups and burning CPU for long grace periods
I noticed that urcu makes exactly _one_ attempt at using futexes
to avoid busy looping on synchronize_rcu. The attached patch instead
switches from busy waiting to futexes after RCU_QS_ACTIVE_ATTEMPTS.
To limit the amount of system calls, reading threads remember whether
they already had a quiescent state in this grace period; if so they were
already removed from the list, and can avoid signaling the futex.
Performance measured with rcutorture (nreaders: 10, nupdaters: 1,
duration: 10, median of nine runs):
RCU_QS_ACTIVE_ATTEMPTS == 100, no patch n_updates = 292
RCU_QS_ACTIVE_ATTEMPTS == 1, no patch n_updates = 290
RCU_QS_ACTIVE_ATTEMPTS == 100, with patch n_updates = 408
RCU_QS_ACTIVE_ATTEMPTS == 1, with patch n_updates = 404
(the first two cases are obviously the same; the only change is
when the futex is used, but over many calls there is no difference).
This patch matches the update to the Promela model.

Futex: turn "int" into "int32_t" for portability
Even though int is 32-bit on all architectures supported by liburcu so
far, make it future-proof by uint a int32_t, which enforces the same
type width used by the system call in the kernel.
Using int32_t and not uint32_t to make comparison with 0 more
straightforward.

cds containers: lfqueue and lfstack: don't depend on a particular rcu flavor
Remove rcu_read lock/unlock from the code, require the caller to ensure
protection. First move towards a single .so for all data containers.
This changes the lfqueue API, which is not very much used yet AFAIK.
