dffb8a67e3 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.

21545ab643 net/local: connect: Fix warning with gcc-arm-none-eabi-5-2016q1. Using compiler from gcc-arm-none-eabi-5-2016q1 toolchain: 
gcc version 5.3.1 20160307 (release) [ARM/embedded-5-branch revision 234589] (GNU Tools for ARM Embedded Processors)

gives error:

  local/local_connect.c:188:7: error: '_local_semtake' is static but used in inline function 'local_stream_connect' which is not static [-Werror]

this is due to compiler enforcing ISO/IEC 9899:1999 6.7.4.3:  "An inline definition of a function with external linkage shall not contain a definition of a modifiable object with static storage duration, and shall not contain a reference to an identifier with internal linkage."

Fix by making inlined caller to have internal linkage as well.

eb344d7260 Fix an assertion noted by Jussi Kivilinna. 
This was a consequence of the recent robust mutex changes.  If robust mutexes are selected, then each mutex that a thread takes is retained in a list in threads TCB.  If the thread exits and that list is not empty, then we know that the thread exitted while holding mutexes.  And, in that case, each will be marked as inconsistent and the any waiter for the thread is awakened.

For the case of pthread_mutex_trywait(), the mutex was not being added to the list!  while not usually a fatal error, this was caught by an assertion when pthread_mutex_unlock() was called:  It tried to remove the mutex from the TCB list and it was not there when, of course, it shoule be.

The fix was to add pthread_mutex_trytake() which does sem_trywait() and if successful, does correctly add the mutext to the TCB list.  This should eliminated the assertion.
