The sproadic_*() macros have become unwieldy. This patch
replaces those convenience macros for global, clustered,
and partitioned scheduling. A part of this API change
is the explicit use of nanosecond time-values. Prior APIs
have used lt_t (litmus time), which had an implied time
scale of nanoseconds.
/bin apps and test suite also updated to use revised API.
Modifications to the test suite are mostly centered around
using nanoseconds instead of milliseconds.

This patch replaces be_migrate_to() with several
be_migrate_*() APIs to automatically assign CPU affinity
masks from a task's partition (or cluster) assignment.
Routines are release-master-aware such that the release
master (if one exists) will NOT be included in the
task's affinity mask. (Note that release-master
avoidance may be overridden by calling
__be_migrate_thread_to_cluster().)

Minor changes to test case code to enable compilation
with 'gcc -O2' (gcc v4.7.2).

This adds the uncache test tool (bin/uncache.c). The tool
can be used to test Litmus's char device driver for allocating
uncacheable CPU memory. The tool runs various checks and
gathers basic cache vs. main memory statistics.
In the future, uncache could be extended to quantify the
benefits of the L1, L2, and L3 caches, instead of treating
them as a black box.
Note: Uncache works best when compiled with '-O2'. While '-O2'
has not been added to the Makefile, other code was updated (code
in tests/ and rtspin), to compile with -O2.
DEPENDS UPON LITMUS-RT PATCH 888d097deb6d1fdc0c89a4f9667fd81cf416cfc7.

Context: priority inheritance triggered a BUG_ON() in fp_common.c.
While at it, add a similar test for the SRP.

Do the basic open/lock/unlock/close test sequence for the MPCP and the
DPCP as well.

|
PCP was only used for DPCP before
tests: add some basic tests for PCP under P-FP
