Pavel Hübner 104714394f kernel: Introduce K_MEM_SLAB_DEFINE_STATIC 
As the already existing macro K_MEM_SLAB_DEFINE results in
two variable definitions, the preceding static modifier leads to
a seemingly working solution, though linkage conflicts will occur
when the same memory slab name is used across multiple modules.

The new K_MEM_SLAB_DEFINE_STATIC macro duplicates the functionality of
K_MEM_SLAB_DEFINE with the difference that the static keywords are
internally prepended before both variable definitions.

The implementation has been tested on my Zephyr project (the build
issue faded out). The documentation has been updated altogether
with all incorrect occurences of static K_MEM_SLAB_DEFINE.

Title: kernel Object Performance

Description:

The SysKernel test measures the performance of semaphore,
lifo, fifo, stack and memslab objects.

--------------------------------------------------------------------------------

Building and Running Project:

This project outputs to the console. It can be built and executed
on QEMU as follows:

    make run

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info

--------------------------------------------------------------------------------
