gcc 7.[1,2] (at least) fails to correctly parse the OSX 10.13 sys/syslog.h
header. As a results we need to potect syslog support in OPAL, PMIX and
ORTE.

This commit looks large, but its really mostly a cleanup step.
1. introduce proper error handling for the return values of fcntl and the fbtl_posix_lock function
2. rename a parameter to more accurately reflect what it does
3. introduce an mca parameter in the fs/ufs component that allows to control
what the level of locking the user would like to enforce
4. move the initialization of the fs_block_size parameter from fs/ufs into the
common/ompio component. An fs component might be allowed to overwrite this
value, but none of the actual fs components do that.

in case a named semaphore is used, it is necessary to close the semaphore to remove
all sm segments. sem_unlink just removes the name references once all proceeses have closed
the sem.

Turns out UCX PML calls opal_pmix.fence in its del procs
method without checking whether or not the fence method
for the pmix component was defined. Rather than patch
UCX PML, actually define a fence method for the cray pmix.

* check that the command succeeds when pre-positioning the file to ensure there isn't an error somewhere in the execution
* properly define srun cmd line options
* terminate the orte-dvm only when it is actually in operation so prun doesn't generate spurious error messages

+ The sshmem verbs component will disqualify itself if this verb isn't
present on the build host.
+ In case where support was requested but not found, don't stop the
build - continue without this component.

We no longer officially support MIPS or ARM before v6. This commit
updates the configury to check for sync builtins on these
architectures and removes the MIPS and IA64 assembly from
opal/include/opal/sys.

Give packagers a configure CLI option to set the value of the MCA
variable mca_base_component_show_load_errors.
The --disable form of this option is intended for Open MPI packagers
who tend to enable support for many different types of networks and
systems in their packages. For example, consider a packager who
includes support for both the FOO and BAR networks in their Open MPI
package, both of which require support libraries (libFOO.so and
libBAR.so). If an end user only has BAR hardware, they likely only
have libBAR.so available on their systems -- not libFOO.so. Disabling
load errors by default will prevent the user from seeing potentially
confusing warnings about the FOO components failing to load because
libFOO.so is not available on their systems.
Conversely, system administrators tend to build an Open MPI that is
targeted at their specific environment, and contains few (if any)
components that are not needed. In such cases, they might want their
users to be warned that the FOO network components failed to load
(e.g., if libFOO.so was mistakenly unavailable), because Open MPI may
otherwise silently failover to a slower network path for MPI traffic.
