5b1f2dff5f iob_tryalloc: Fix throttled allocation 
If threads are blocking for throttled allocation,
g_throttle_sem.semcount doesn't represent the number of
usable IOBs well.

Note: For non-throttled allocations, the g_iob_committed mechanism
is a rescue. But there is no equivalent for throttled allocations.

5c0e8e88b1 Revert "Makefile: move INCDIROPT to common place (#625)" 
This reverts commit b9ace36fcc.

This change was added by PR 625 but has a serious logic flaw.  It removes all occurrences of INCDIROPT and replaces it with a definition in tools/Config.mk:

    else ifeq ($(WINTOOL),y)
      DEFINE = "$(TOPDIR)/tools/define.sh"
      INCDIR = "$(TOPDIR)/tools/incdir.sh" -w

This logic flaw is the Config.mk is included in all Make.defs files BEFORE WINTOOL is defined.  As a result, the definition is wrong in many places when building under Cygwin with a Windows native toolchain.

6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

Iobinstrumentation

* mm/iob: Introduces producer/consumer id to every iob call. This is so that the calls can be instrumented to monitor the IOB resources.

* iob instrumentation - Merges producer/consumer enumeration for simpler IOB user.

* fs/procfs: Starts adding support for /proc/iobinfo

* fs/procfs: Finishes first pass of simple IOB user stastics and /proc/iobinfo entry

b21c12bd18 Fix errors found in build testing: 
arch/mips/src:  Previous commit used CP0 register definitions that were not defined in the cp0.h header file.  Probably these were from the Microchip hacked up GCC toolchain but are not generally available.  Fix:  Add definitions to NuttX cp0.h header file.

mm/iob:  Eliminate some warnings about testing the value of an undefined pre-processor variable.
