because not all compiler support the weak attribute, and
many features are either always used or guarded by config.

spinlock: Remove SP_SECTION
...
Summary:
- SP_SECTION was introduced to allocate spinlock in non-cachable
region mainly for Cortex-A to stabilize the NuttX SMP kernel
- However, all spinlocks are now allocated in cachable area and
works without any problems
- So SP_SECTION should be removed to simplify the kernel code
Impact:
- None
Testing:
- Build test only

sched/irq and sched/sched: Measurement of interrupt handler duration used to be available only in Tickless mode since it used the high resolution Tickless timer to measure interrupt time. This commit adds CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the interrupt duration caculation to use the same high-resolution, platform-specific timer as is used with the Critical Section Monitor. This leads to two improvements: (1) You can now measure interrupt duration in non-Tickless mode, and (2) in either mode, the interrupt duration and the critical section measures will use the same high-resulotion timer and should, therefore, never be any descripancy due to different clock sources.

sched/irq: Add support interrupt chains in NuttX. IRQ chain is very useful in these cases: (1) Multiple hardware connect to the same request line(e.g. PCI), (2) Need multiple driver to support one hardware block (like Linux MFD)

Implements support for smaller interrupt tables as described at http://www.nuttx.org/doku.php?id=wiki:howtos:smallvectors . This is largely the work of Mark Schulte. However, I have made several changes to match with the Wiki document. If you like the change, thanks go to Marc. For any errors you can blame me.
