* Basic support for memory allocation on GPU using CUDA unified memory. Partially addressing #284. IOR support completed.
* Support for GPU alloc in MDTest and MD-Workbench
* Option: support repeated parsing of same option (allows option sharing across modules).
* Checks for gpuDirect
* Integrate gpuDirect options and basic hooks, more testing to be done.
* POSIX: basic gpuDirect implementation working with fake-gpudirect library.
* CUDA allow setting of DeviceID for IOR (not yet MDTest).
* CUDA/GPUDirect Support --with-X=<path>
* Bugfix in option parser for flags that are part of an argument for an option, e.g., -O=1, if 1 is a flag it is wrongly assumed to be a flag.
For now, and compatibility, IOR options can still be set/internally accessed using the backends init_xfer_options.
This should be removed in the long run to strip away this dependency.
Fix the configure check if --with-lustre is specified, but
the linux/lustre/lustre_user.h header is not present. Only
one of the headers needs to be included if both are found.
In some cases, FASYNC is not defined, but forms part of the
O_LOV_DELAY_CREATE value, add a #define in that case.
Fixes#115.

Context: Some backends may have used different names in
the past (like IME backend use to be IM). Legacy scripts
may break.
This patch adds a legacy name option in the aiori structure.
Both name and legacy name work to select the interface.
But the following warning is printed if the legacy name is used:
ior WARNING: [legacy name] backend is deprecated use [name] instead.
It shares the create/open/delete/set_version/get_file_size
functions with POSIX backend.
The mmap backend also supports fsync and fsyncPerWrite options,
and it will use msync() instead and fsync().

This commit makes changes to the AIORI backends to add support for
abstacting statfs, mkdir, rmdir, stat, and access. These new
abstractions are used by a modified mdtest. Some changes:
- Require C99. Its 2017 and most compilers now support C11. The
benefits of using C99 include subobject naming (for aiori backend
structs), and fixed size integers (uint64_t). There is no reason to
use the non-standard long long type.
- Moved some of the aiori code into aiori.c so it can be used by both
mdtest and ior.
- Code cleanup of mdtest. This is mostly due to the usage of the IOR
backends rather than a mess of #if code.
