Squashed commit of the following:
tools/gencromfs.c: Seems basically functional but has not has not yet been integrated with CROMFS.
tools/gencromfs.c: Revist previous commit. Let's make no assumptions about the compatibility of the host system and NuttX.
tools/gencromfs.c: I think access mode bits are sufficiently standard that we can just copy them from the host. This is don't mostly to pick up the executable bits and other conbinations of bits without doing a bit-for-bit decode.
tools/gencromfs.c: Code complete but only partially functional.
tools/gencromfs.c: type definitions must precede data definitions
tools/gencromfs.c: Adds a little more logic to gencromfs tools. Still not complete but can traverse directories and generate directory and hard-link nodes.
tools/gencromfs.c: Beginning of a genromfs tool that will eventually be used for generation of CROMFS file system images.
Squashed commit of the following:
fs/cromfs: Now depends on EXPERIMENTAL because it is not yet verified.
fs/cromfs: This commit brings the CROMFS file system to code complete. Still completely untested. Next steps: Need a tool to generate CROMFS file system images and a test case under apps/
fs/cromfs: Add logic to traverse the in-memory file system nodes.
fs/cromfs: Add initial support for an in-memory, compressed, read-only file system.
sched/sched: Correct some build issues introduced by last set of changes.
sched/sched: Add new internal OS function nxsched_setaffinity() that is identical to sched_isetaffinity() except that it does not modify the errno value. All usage of sched_setaffinity() within the OS is replaced with nxsched_setaffinity().
sched/sched: Internal functions sched_reprioritize() and sched_setpriority() no longer movidify the errno value. Also renamed to nxsched_reprioritize() and sched_setpriority().
sched/sched: Add new internal OS function nxsched_getscheduler() that is identical to sched_getscheduler() except that it does not modify the errno value. All usage of sched_getscheduler() within the OS is replaced with nxsched_getscheduler().
sched/sched: Add new internal OS function nxsched_setparam() that is identical to sched_setparam() except that it does not modify the errno value. All usage of sched_setparam() within the OS is replaced with nxsched_setparam().
sched/sched: Add new internal OS function nxsched_getparam() that is identical to sched_getparam() except that it does not modify the errno value (actually, the previous value erroneously neglected to set the errno value to begin with, but this fixes both issues). All usage of sched_getparam() within the OS is replaced with nxsched_getparam().
configs/flipnclick-sam3x: Add support for the 4 user-controllable LEDs on the board.
configs/flipnclick-sam3x: Add board support for the Mikroe Flip&Click SAM3X.
configs/arduino-due: Update this old configuration so that it is structured a little more like recent board support.
fs/nxffs: Giving up on truncate() support in NXFFS for now. There is too much that has to be done to make that work.
configs/sim: Add support for testing NXFFS.
fs/smartfs: Add logic needed to ftruncate to shrink a file to any arbitrary size.
fs/smartfs: Repartition some functionality to better fit in new ftruncate features.
FAT. Effectively handles the situation when a new file position is within the current sector.
* Find begin of the next token
* EOL
* revert
* Accelerates the work of the FS with a multitude of operations to write small pieces of data within the current sector.

Squashed commit of the following:
fs/fat: Resolves issues with truncating the cluster chain when shrinking files via ftruncate().
fs/fat: First cut at implementation file shrinkage logic needed to support ftruncate(). Certainly shrinks the file size but it does not appear to correctly disconnect the cluster chains.
fs/fat: Restructure some functions in files to better support forthcoming file shrinkage logic. Put framework for file shrinkage in place. That logic is incomplete on initial commit.
fs/nxffs: Add partial implementation of the truncate method: It extend files, but cannot yet shrink them.
fs/smartfs: Add partial implementation of the truncate method: It extend files, but cannot yet shrink them.
fs/fat: Add partial implementation of the truncate method: It extend files, but no yet shrink them.
fs/nfs: Add support for the truncate method to the NFS file system.
fs: Add truncate() support for userfs
fs/unionfs: Add truncate() support to the unionfs
fs/tmpfs: Add ftruncate() support to tmpfs
syscall/: Add system call support for ftruncate()
net/route: Adding ftruncate() support eliminates an issue in file-based routing table management.
fs: Add basic framework to support truncate() and ftruncate(). The infrastructure is complete. Now, however, the actual implementation of ftruncate() will have to be done for each file system.
