Andrew Boie f0835674a3 lib: os: add sys_mutex data type 
For systems without userspace enabled, these work the same
as a k_mutex.

For systems with userspace, the sys_mutex may exist in user
memory. It is still tracked as a kernel object, but has an
underlying k_mutex that is looked up in the kernel object
table.

Future enhancements will optimize sys_mutex to not require
syscalls for uncontended sys_mutexes, using atomic ops
instead.
