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.

Test USB Echo functionality on discovery-stm32f072 board to
ensure that queues still function correctly.
