Per OpenGroup.org, syslog -- and, hence, nonstandard vsyslog, and debug wrappers -- does not return a value. Rename _vsyslog to nx_vsyslog. Use internal nx_vsyslog in the few cases where a return value is required.

Squashed commit of the following:
...
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.

sched/signal/sig_nanosleep.c and libc/time/lib_nanosleep.c: Implement clock_nanosleep(). nanosleep() is now reduced to a libc wrapper around clock_nanosleep().

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.

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.
