New queue suspend/resume update can now return the number of successful
queue requests so return success if IOCTL return is non-negative.
This should be backwards compatible since old queue suspend/resume returns
0 on success.

The debug trap accesses the data0/data1 registers, so we do not
want the userspace to write values to it. We remove the calls to
set the data0/data1 register values.

To support adding new features to the kfd debugger, and not break
functionality, we need to be able to check the kfd debugger support
version info from the kernel.

The queue IDs passed over to the kernel via kfd_ioctl_dbg_trap_args->ptr
should be a list of uint32_t's. Need to convert from the passed in
64 bit HSA_QUEUEID to 32 bit uint32_t's.

There was a mistake and RESUME was used when it should
have been suspend in two places in the suspend resume
code. This fixes that error.

This is updating to the new suspend and resume API for the
KFD and the thunk. We now support passing in a list of queues
to suspend, and not just all of the queues for the process.
The kfdtest testcase was also updated so it still compiles.

Child process hsaKmtOpenKFD() call must re-initialize global variables
copied from parent process. This includes close all file handles, free
dynamically malloc buf. Double free issue is because destroy_device_
debugging_memory() free the memory in parent process hsaKmtCloseKFD()
but don't reset it to null pointer. As a result, child process free it
again. kfd_fd is closed in parent process but don't reset to 0, so
child process close it again.
Fix: reset kfd_fd to 0 after close, reset is_device_debugged pointer to 0
after free

Use checkpatch.pl to fix the majority of errors. Some that remain and
will be excluded:
Use of typedefs/externs/volatile/sscanf
Lines over 80 characters
Remaining errors are due to misunderstanding the * symbol with typedefs
Also use this opportunity to spell manageable properly

This change breaks the ABI, and aligns it with the upstream ABI.
It also fixes some ioctl structures that are not 64-bit safe and
consolidates ioctl numbers.
