class tests: change from opal_init() to opal_init_util()
class tests: re-enable a bunch of tests

Many of these tests were failing due to opal_init() failing in some
cases (because the opal shmem framework needs installed components, so
"make distcheck" would fail these tests because the opal shmem
components were not installed).  However, all of these tests seem to
be fine with opal_init_util() -- so let's re-enable these tests.
Whitespace cleanup only; no code changes
test/class: update class tests to also use opal_finalize_util
.gitignore: ignore executes for new tests

With PGI compile we need stdarg.h for va_list define
libfabric: don't use __thread

There's no real reason that this routine should use thread local
storage.  Plus, __thread appears to be a GCC extension.
libfabric psm: fix (void*) dereference

Committed upstream to libfabric as well.
Change logging function name from log to logfn.  Fixes issue with PGI compile
btl/vader: fix compile on SGI UV
btl/vader: adjust xpmem_make limit

If there is any chance of vader working on SGI UV the limit needs to
match what the old SGI kernel module expects. In this case if the
limit is larger than the max address in the process then we must use
(size_t) -1.
