Isaac Lozano a1555559ab util: Improved qemu_hexmap() to include an ascii dump of the buffer
qemu_hexdump() in util/hexdump.c has been changed to give also include a
ascii dump of the buffer. Also, calls to hex_dump() in net/net.c have
been replaced with calls to qemu_hexdump(). This takes care of two misc
BiteSized Tasks.
