Previously there was just a memcpy_usbram that copied to USB packet memory, and no routine to copy out. This adds the "from" version and renames and improves to "to" version. The improvement is that the new "to" version correctly handles unaligned beginning and endings of the region to be copied. These need to be read/modify/write accesses since the USB packet ram has to be manipulated in 16-bit chunks.
