Useful when attempting to serialize potentially very large data
structures and send them to API clients. NULL pointer checks are
MANDATORY when calling xxx_or_null(...) variant functions.

Simply put, threads cannot sleep waiting for the vlib memory api main
input queue to drain. If, say, thread i (i !=0) fills the vlib api
main input queue with rpc requests - and then blocks trying to add
another request - the game is over.
RPCs attempt a barrier synchronization, which fails with Pr = {1.0}
because thread i is in a mutex/condvar sleep.
Add a main-thread cut-through path, which directly invokes the RPC
callback function when called on the main thread.

Accidentally removed pthread_mutex_unlock (&root_rp->mutex) in the
dead client scan case. Oops. Bad idea.

Use the command line argument "api-segment { uid <nnn> gid <nnn> }" to
configure shared memory segment file ownership. Defaults to uid = gid
= 0. Shared-memory segments are explicitly set to 0770 mode, aka
"rwxrwx---".

gcc version 4.9.2 (Raspbian 4.9.2-10)
Tested on Linux raspberrypi 4.4.6-v7+ #875 SMP Tue Apr 12 16:33:02 BST 2016 armv7l GNU/Linux
CPUs may be little or big endian, detect with gcc flags, not the processor architecture
Add a new flag $(PLATFORM)_uses_openssl which allows to disable the link with openssl lib.
vlib/vlib/threads.c:
startup.conf must:
- specify the heapsize as we don't have hugepages on raspbian
cpu {
main-core 3
}
heapsize 64M
Corrects in various files the assumption uword == u64 and replaces 'u64' cast with 'pointer_to_uword' and 'uword_to_pointer' where appropriate.
256 CPUs may create an OOM when testing with small memory footprint ( heapsize 64M ), allows the number of VLIB_MAX_CPUS to be set in platforms/*.mk
vppinfra/vppinfra/longjmp.S:
ARM - copy r1 (1st parameter of the setjmp call) to r0 (return value)
vppinfra/vppinfra/time.h:
On ARMv7 in AArch32 mode, we can access to a 64bit register to retreive the cycles count.
gcc on rpi only declare ARM_ARCH 6. Override this info, and check if it is possible to use 'mrrc'.
/!\ the time function will NOT work without allowing the user mode access to the PMU.
