e3108813cc Revise misleading instructions in sample project README.txt files
Removes the instruction directing users to issue "make pristine"
before building a sample project, as this should be unnecessary
under normal circumstances and can cause the user to unexpectedly
lose their current configuration information. In its place, a section
on troubleshooting is added that describes how to rebuild a project
using the desired configuration.

a1bd59de35 Eliminate obsolete coding convention comments
Gets rid of single-line comments required by a previous set of
coding conventions. These comments provide no value to readers
and just clutter things up.

4fe98a46f5 Initialize stack area in _NewContext()
Instead of initializing the stack (when INIT_STACKS is enabled) in start_task()
and _fiber_start(), do it in _NewContext().  This helps to both reduce code
duplication AND ensure that all contexts get an initialized stack (previously
the background/idle task's was missed).

bbe84f8ae5 Use ccflags-y and asflags-y instead of EXTRA_CFLAGS
According to section 3.7 of Documentation/kbuild/makefiles.txt, using
EXTRA_CFLAGS in Makefiles is "still supported but their usage is
deprecated." However, using make EXTRA_CFLAGS="-DSOMETHING" results in
EXTRA_CFLAGS from Makefiles being overwritten, obviously breaking the
build.  This patch converts to them to the newer ccflags-y which also
fixes the problem.

40b5200c73 Optimizations to _NewContext() and _NewContextInternal()
Since the address of the new context is known before _NewContext() is invoked
(due to it being passed a properly aligned stack), there is no longer any
need for _NewContext to return the pointer to the context.

Furthermore, as a direct result of the properly aligned stack, the pointer to
the new context does not need to be passed as a separate parameter since it
will always match the passed stack pointer.

e948817ee5 Reduce floating point test duration
The length of time it took for the microkernel's test_fp_sharing test to run
was occasionally causing issues with sanity_chk.  The test would take close
to five minutes to finish and sanity_chk has a five minute timeout for the
tests.  To resolve this, the number of iterations for which the test executes
has been cut in half (from 1000 to 500).
