There was a reference counting problem in the TPC logic of net_clone(). net_clone() which is the common logic underlying dup() and dup2() for sockets. When net_clone() calls net_start_monitor() and net_start_monitor() returns a failure (because the underlying TCP connection) then net_clone() must back out the reference count on the structure. Problem noted by Pascal Speck and this implementation of the solution is based on his suggestion.

drivrs/mtd/filemtd.c: add block device MTD interface. Block MTD interface allows using block device directly as MTD instead of having to use file-system in between. NOTE that this provides the opposite capability of FTL which will let you use an MTD interface directly as a block device.

Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep().

MTD M2PX: If we READ while a write/erase is pending, the command is ignored and the write/erase continues. If we dont catch this situation we will return garbage to the user because the flash will not execute the command. So READ MUST wait for write completion, and before that, the bus must be locked since it's a precondition to calling waitwritecomplete().

...
These parts utilize the same one-byte-address in the I2C protocol as the -02,
but requires different I2C addresses for different banks of the EEPROM.
