Fix data race in asn1_str2tag() on tntmp which was accidentally made static

Variables tntmp and tnst are declared in the same declaration and thus
share storage class specifiers (static). This is unfortunate as tntmp is
used during iteration through tnst array and shouldn't be static.
In particular this leads to two problems that may arise when multiple
threads are executing asn1_str2tag() concurrently:
1. asn1_str2tag() might return value that doesn't correspond to tagstr
   parameter. This can happen if other thread modifies tntmp to point to
   a different tnst element right after a successful name check in the
   if statement.
2. asn1_str2tag() might perform an out-of-bounds read of tnst array.
   This can happen when multiple threads all first execute tntmp = tnst;
   line and then start executing the loop. If that case those threads
   can end up incrementing tntmp past the end of tnst array.

rcu: Ensure that updates to the ID field of a qp don't lose refs

ppc64le occasionally still fails the threadstest on __rcu_torture

From several days of debugging, I think I've landed on the problem.

Occasionally, under high load I observe the following pattern

CPU0                                     CPU1
update_qp                                get_hold_current_qp
  atomic_and_fetch(qp->users, ID_MASK, RELEASE)
                                         atomic_add_fetch(qp->users, 1, RELEASE
  atomic_or_fetch(qp->users, ID_VAL++, RELEASE)

When this pattern occurs, the atomic or operation fails to see the published
value of CPU1 and when the or-ed value is written back to ram, the incremented
value in get_hold_current_qp is overwritten, meaning the hold that the reader
placed on the rcu lock is lost, allowing the writer to complete early, freeing
memory before a reader is done reading any held memory.

Why this is only observed on ppc64le I'm not sure, but it seems like a pretty
clear problem.

fix it by implementing ATOMIC_COMPARE_EXCHANGE_N, so that, on the write side in
update_qp, we can ensure that updates are only done if the read side hasn't
changed anything.  If it has, retry the operation.

With this fix, I'm able to run the threads test overnight (4000 iterations and
counting) without failure.

Returning a non-zero result size that isn't larger than the

Make the provider context available to encoders
