Register and map userptrs through Shared Virtual Memory(SVM) API at
the Kernel level when available. Using this approach, performance
will be improve as register/unregister memory will not trigger any
system call to KFD driver.

Engine offset that is the maximum number of engines is still valid
as offset enum 0 is occupied by blit copies so raise the limit by 1.

Adds hsa_amd_portable_export_dmabuf and hsa_amd_portable_close_dmabuf
which allow obtaining dmabuf handles to rocr allocations. These handles
may be shared with other APIs to support cross vendor & cross device
memory sharing.
Adds query to return whether dmabuf export is supported

The MemoryAllocAll test in kfdtests exercises the new KFD memory
availability API by trying to allocate a single buffer object that
exactly fills all of vram. Desired object size is determined using the
memory availility KFD ioctl via libhsakmt, then an object is allocated
slightly larger than that size. If the allocation attempt fails then
the test tries to allocate a slightly smaller object, and continues
trying with smaller sizes until the allocation succeeds. The test
succeeds if the successfully allocated object is within some specified
tolerance of the available memory reported.
There are a number of known issues that can cause the successfully
allocated object to be significantly smaller than reported availability.
Until these issues are addressed, we should not fail the test, but just
log the actual divergence between the size of the object we thought we
could allocate, and what was actually possible.

Implement hsaKmtExportDMABufHandle, which can be used for a new
upstreamable RDMA solution. It exports a DMABuf handle for an arbitrary
virtual address along with the offset of the address within the
allocation. It also checks that the size of the intended export does
not exceed the allocation.
This uses the new AMDKFD_IOC_EXPORT_DMABUF, which requires KFD ioctl
API version 1.12.

ROCr internally uses the same allocation_map_ list to track memory
allocations that are both for internal allocations and allocations by
users of ROCr library. In some edge cases, the library user would call
hsa_amd_pointer_info on an invalid pointer, but ROCR would return the
pointer as valid because this pointer belongs to a memory range that
was allocated internally within ROCr. Adding a flag to differentiate
between internal and external allocations.

Fixes hang due to change in order of initialization of libraries
that have cyclical dependencies and they call hsa_init() during their
initialization phase.
This implementation looks for a symbol called "HSA_AMD_TOOL_PRIORITY"
across all loaded shared libraries using dynamic section entries of the
loaded lib instead of using dlopen and dlsym for the same purpose.
