drivers/serial/tcdrain: tcdrain() was recently added to the NuttX C library. But there is a problem. The specification of tcdrain() requires that it be a cancellation point. In order to do this, tcdrain was moved from the C library into the OS and the addition cancellation point hooks were added. In non-FLAT builds, access via system calls is also now supported.

syscall/: The non-standard interface exec() is now enshrined as a official NuttX API. I really dislike doing this but I think that this is probably the only want to load programs in the protected mode. It is currently used by some example code under apps/ that generate their own symbol tables for linking. Other file execution APIs relay on a symbol table provided by the OS. In the protected mode, the OS cannot provide any meaning symbol table for execution of code in the user-space blob so that is they exec() is really needed in that build case. And, finally, the interface is completely useless and will not be supported in the KERNEL build mode where the contrary is true: An application process cannot provide any meaning symbolic information for use in linking a different process.

pthreads: Move pthread_barrier_init, pthread_barrier_destroy, and pthread_barrier_wait from sched/pthreads to libc/pthreads. This just coordinate other OS interface calls but are not a fundamental OS interfaces and, hence, do not belong within the OS.

Add entropy pool and strong random number generator
...
Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output.
Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.

Syscalls: Remove modsym() syscall. There is no reason why appication code could ever use symbolic information from a symbol within a kernel module. The modsym() interface is only meaningful within the kernel.

POSIX message queues: Move mq_setattr() and mq_getattr() from nuttx/libc/mqueue to nuttx/sched/mqueue. Also add sysyscall support for mq_setattr() and mq_getattr(). This is necessary in protected and kernel builds because in those cases the message queue structure is protect and cannot be accessed directly from user mode code. Noted by Jouko Holopainen.

boardctl(): Add a new non-standard OS interface. This is similar to a driver IOCTL call. But this is an IOCTL call directly on the board logic. This function will eventually replace all of the ad hoc OS interfaces that are current used to perform application specific intialiation and application driver test confifuration. It essentially formalizes and institutionalizes these rogue interface in to at least a single crazy call.

gettimeofday() and settimeofday(): Move gittimeofdady() from sched/clock to libc/time. All remove gettimeofday() from NuttX system calls. It is only a wrapper around clock_settime() and does not need a trap. gettimeofday() is no longer tried as a core OS interface.
...
gettimeofday has been decremented in POSIX 2008. settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry.
