Previously, during the rsmi_init discovery process, the existence
of an hwmon# directory was used to distinguish between gpus nodes
and non-gpu nodes. This isn't reliable in some scenarios. Instead,
the existence of the vbios_version file is used as an
indicator that the node is indeed a gpu.

The purpose of this patch is to implement GPU reset functionality
in the LIB, and to call it from the rocm_smi python CLI.

If we fail to find an expected temperature or voltage label
file, previously we were attempting to re-add a mapping of file
index to sensor types. Attempting to insert a map item that is already
present has no effect, so there should be no functional change.
This was a remnant of old code that should have been deleted.

[ROCm/rocm_smi_lib commit: bb5132a66c]
The environment variable RSMI_DEBUG_INFINITE_LOOP is introduced
to facilitate debugging RSMI in user applications. When this
env. variable is non-zero, an infinite loop will be entered in
rsmi_init(). At this point, a debugger can be attached and RSMI
can be debugger. This only applies to debug builds.

Some rsmi apps fail without much explanation when
rsmi_init() fails. This patch hopes to provide some clues to
the reason for the failure.

Previously, when a process holding a shared mutex was killed,
the next time an RSMI application was started, it would not be
able to obtain the mutex--the application would have to exit.
This fix uses pthread_mutexattr_setrobust() to detect this
situation and act accordingingly.
Also, add some missing, needed mutexes and move mutexes
closer to where the protect resource is used.

A special mode of operation to achieve minimal performance variation by letting
the user have the ability to provide the desired frequency to be set as the soft limit.
The user can control the entry and exit to the mode via rocm-smi a mechanism to
enter / exit performance determinism mode as below.
Enter performance determinism mode:
- hold a lock
- write performance_determinism to power_dpm_force_performance_level
- write input clk_freq to pp_dpm_sclk
- release lock
Exit performance determinism_mode:
- hold a lock
- write auto to power_dpm_force_performance_level
- release lock

Event bitmask in KFD SMI event is now replaced with event index in
the SMI event message. Sending a event bitmask, which was a 64-bit
field with only 1 bit set, was quite wasteful of memory and also
potentially limiting to 64 events. Instead the kernel would send
event index in the SMI event message. As a result, update the
KFD SMI event handling to expect the event index in the message.

[ROCm/rocm_smi_lib commit: b015052a07]
Some systems have kfd sysfs properties entries that
are unreadable--for example, when a multi-gpu system is
dividing the gpus among containers, each container may
only be able to access certain gpus.
Previously, all kfd topology node properties entries were
assumed to be valid. Now, we check for readability before
declaring them "valid".
Fixes SWDEV-240169
Also:
* remove an assertion that would happen when no pcie
device identifier files are found on the system.
* fix cpplint issues

EPERM. In fact, if it doesn't return EPERM, it is an
indication of a problem. This commit adjusts accordingly.

This fixes a seg fault that would happen in release builds when
there are no KFD nodes on a system, which occurs when there are
not AMD gpus present in the system. This use case occurs
for higher application code that is meant to be gpu agnostic.

* Don't make different shared memory mutexes for different users
* Don't delete (unlink) the shared mutex file if the mutex
initialization fails. This may mess up other processes that
are using it. Instead, print a message on how to resolve the
situation, and then throw an error.
Note, this situation comes up when debug builds (usually)
either assert() or otherwise end execution without a proper
clean up.
* Remove cpplint from shared_mutex code
