Add pc-rtems BSP to OSAL

[skliper]

For development under RTEMS it is helpful to have a basic BSP that does not require any special development boards.

The RTEMS project provides this via the "pc686" BSP. This makes it possible to boot and run an RTEMS application on ordinary commodity PC hardware.

This also boots and runs in virtual machines i.e. QEMU which is very desirable for testing.

This ticket will add a "pc-rtems" BSP to OSAL that can be used for this purpose.

Pushed branch "trac-29-pc-rtems", commit [changeset:eec4f2f]

This adds a simple RTEMS BSP that runs using the "pc686" BSP from the upstream RTEMS.

This changeset has been rebased to the (unapproved) 2015-04-14 baseline

This is due to a dependency on files added/changed as part of that baseline. Attempting to base this change on the official 2015-02-26 OSAL is potentially possible but will result in merge conflicts when putting these back together again.

The new commit is [changeset:22da0be]

Accept, based on the [changeset:cb82d8f] commit. I'm not an RTEMS
expert and can't test it -- but presuming it works, it seems like
a slam-dunk to include it.

== REBASED AND UPDATED ==

For the 2015-07-14 CCB review/discussion

This has been rebased to the current OSAL development baseline, commit [changeset:c50630e] reflects the current proposed modifications.

In addition to adding the pc-rtems BSP, this also integrates with the unit testing framework that was approved at the 2015-06-30 CCB so that the unit tests can be executed on RTEMS using this BSP.

This has been tested by running the a pc686 RTEMS build in QEMU and confirmed that all unit tests are passing in this environment.

(with the caveat that I'm not an RTEMS expert,
and do not currently have an RTEMS build environment)
