Sergio Rodriguez 2e2ad8166e qemu: Creation of QEMU specific platforms 
Setting up new platforms to handle emulation, and make them the only
ones able to run on QEMU from the Makefile "qemu" target to avoid
confusion with other platforms. We have now platform qemu_x86 and
platform qemu_cortex_m3, also modification to the sanity checks to have
qemu support only on those platforms

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

    make qemu

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

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


Problems with QEMU on ARM:
Qemu v2.1 for ARM platform do not support tickless idle. If run the sample
project in QEMU with the CONFIG_TICKLESS_IDLE option enabled, the project
could present an erratic behaviour.
