The current CMSIS v2 implementation is clearly assuming that timeout
arguments being passed to e.g. osDelay() are in units of Zephyr ticks,
not milliseconds as specified by ARM or (inconsistently) assumed by
our test code.
Most tests work with the ~100 Hz default tick rate, but they tend to
fail on precision issues at higher tick rates. Force the CMSIS v2
applications to be 1000 Hz for now as a workaround, and detect the
mismatch as a build failure.

Changed the print format for unsigned 32-bit variables that produced
warnings when compiled with newlib instead of the standard C library.
Chose to replace %d with PRIu32 because the latter is more portable
and adapts to the types of the standard C libraries.
Tested with and without newlib, and with sanitycheck.

If any of the Zephyr version numbers went beyond 99, the "%2d" printf
specifiers would expand to fit and the string would run over the
memory on the stack used for os_str[].
Recent GCC versions (remember native_posix and x86_64 use the host
compiler) were actually detecting this and correctly issuing a warning
(but only if the 3-digit char value would overflow the actual array
size!), which was breaking sanitycheck for me on Fedora 28 and Ubuntu
18.04 build hosts. Pretty impresive warning.
As it happens this was wasteful anyway; we were spending bytes on the
stack (and in rodata to store the constant which, and the cycles
needed to copy it into place on the stack where it would be
overwritten immediately) when we could just snprintf() directly into
the buffer the user gave us.

APIs to introduce wait i.e osDelay and osDelayUntil are defined
here. They are analogous to k_sleep in the kernel.

Implement support for Kernel management APIs like
osKernelInitialize, osKernelGetTickCount, osKernelGetSysTimerCount
etc.
