Anton Staaf dc1362ca82 Queue: Add methods that accept a memcpy routine ...

These versions of the queue add and remove methods support
using memcpy like routines to access regions of memory with
specific requirements.  In particular, this will allow for
transfers between queues and USB packet RAM on the STM32
which has specific access requirements.

This change also includes an update to the mem* util routines
to make their prototypes compatible with C89 and POSIX
standards.
