Log Message:
-----------
threads::shared: remove problematic err.t test
This test checks that a warning is issued when two threads call
cond_wait() for the same condition var, but with different locks.
The problem is that shared.xs then calls the underlying OS's cond_wait()
functions with similarly bad values, triggering undefined behaviour. On
some platforms this caused pthreads_cond_wait() to return an error code,
triggering a panic and deadlock.
So just remove the test.

Log Message:
-----------
threads.xs: remove unneeded locking
After some refactoring, there was a vestigial piece of locking around
a PerlMemShared_malloc() call in S_ithread_create(). Remove it, since
its unnecessary now.
