Also, don't return an error for empty sysfs files. The reserved memory
page file will often have no lines. We don't want it to appear that
this function is not supported if the file is empty.

Add support and testing for reading the Unique ID associated with a
specific GPU. This ID will persist across reboots, even if the GPU is
moved to a different machine. Note that this is per-GPU, not per-card,
as some cards have multiple GPUs, and each GPU will get a unique
identifier

* If vendor/device/subsystem name is not found, use device ID string
* Update documentation for get-name functions
* Add support for junction, edge and memory temperature sensors
With newly added initialization parameters that can be
passed to rsmi_init(), you can tell RSMI to consider other
devices.
Also:
-fixed incorrect header file name that would break in C
builds
-modified rsmi_init() and rsmi_shut_down() to reinitialize and
clear static structures

This commit uses a pthread mutex in shared memory to prevent
almost all cases of multiple processes simultaneously
reading/writing to device sysfs files. The main existing race
condition is when 2 processes are starting at the same time,
setting up their shared memory and mutexes. Since this is meant
to prevent collisions among thread and processes, the small
shared memory segments (big enough for a pthread_mutex) will
persist until reboot.
In some cases, the fan sysfs files will exist even if the device
doesn't have a fan. In these cases, the tests will give apparently
random results.
Also, remove documentation and ifdef'd test of debugfs related
power functions.
