libcaf_shmem doesn't currently build on Solaris. Previously this went
unnoticed because the AX_PTHREADS autoconf macro erroneously didn't
detect pthreads support. Once this is fixed, compilation fails:
In file included from caf/shmem/supervisor.h:35,
from caf/shmem/alloc.c:31:
caf/shmem/sync.h:46:25: error: conflicting types for ‘lock_t’; have
‘caf_shmem_mutex’ {aka ‘struct _pthread_mutex’}
46 | typedef caf_shmem_mutex lock_t;
| ^~~~~~

from caf/shmem/alloc.c:29:
/usr/include/ia32/sys/machtypes.h:50:25: note: previous declaration of ‘lock_t’
with type ‘lock_t’ {aka ‘unsigned int’}
The lock_t definition in <ia32/sys/machtypes.h> is benign: POSIX.1
reserves the _t suffix for the implementation. At the very least the
code should use a properly prefixed type instead, which this patch does
by changing the code to use caf_shmem_lock_t instead.
Bootstrapped without regressions on i386-pc-solaris2.11,
sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.
Ok for trunk?
