Combine "pc-linux" and "pc-linux-ut" OSAL BSPs

[skliper]

There is a separate BSP called {{{pc-linux-ut}}} that is used for unit testing. This differs slightly from the normal {{{pc-linux}}} BSP:

• It does not block signals
• It does not have an idle wait at the end of {{{main()}}}

Having a different BSP violates the "fly what you test, test what you fly" philosophy.

The unit tests driven by timers do not work with signals blocked, because these rely on signals working during {{{OS_Application_Startup()}}} in order to function. This is probably the reason for the alternate BSP.

However, these tests can and should be fixed to operate using the normal BSP with signals blocked, as this will be more representative of what happens in a normal system. To fix these tests just requires creating a child thread to handle the test logic and allowing {{{OS_Application_Startup}}} to complete normally.

This was originally done as part of #40, but cherry-picking this modification out of that change set since it is required to make unit tests work in the current integration candidate ({{{ic-2015-0616}}} branch).

Pushed [changeset:7f36448] for review. This is also merged into the {{{ic-2015-0616}}} branch and the unit tests build/run successfully as part for that merge.

It makes sense to have only one BSP if possible. Recommend accept.

Recommend accept.

From a design standpoint, I like this change as it
encourages "test what you fly, fly what you test."

NB: I did have to go look at the real source for
the bin-sem-timeout-test as the diff left me unsure
about exactly what code moved where. Looks good.
