Anas Nashif 2bc9d69981 build: abstract emulation and replace qemu goal with run
This will replace the current goal of 'make qemu' with 'make run' and
moves Qemu handling into its own file and into the boards instead of
being architecture specific.

We should be able to add new boards that support some other type of
emulation (by adding scripts/Makefile.<emu type>) and allow the board to
define their own options for the use type of emulation.

'make qemu' will still work, however it will be deprecated, starting
with this commit it is recommended to use 'make run'.

Title: Kernel Event Logger Sample

Description:

This sample uses the philosopher sample with two additional tasks to show the
profiling data on different system's states. The fork manager task controls the
fork's availibilty. The worker task performs intermitently heavy processing,
allowing or preventing the system to go idle.

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

Building and Running Project:

This nanokernel project outputs to the console. It can be built and executed
on QEMU as follows (only x86 and ARM platforms):

    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
