10e4927bc4 util/hexdump: Inline g_string_append_printf "%02x" 
Trivial arithmetic can be used for emitting the nibbles,
rather than full-blown printf formatting.

53ee5f551e util/hexdump: Use a GString for qemu_hexdump_line 
Allocate a new, or append to an existing GString instead of
using a fixed sized buffer.  Require the caller to determine
the length of the line -- do not bound len here.

13dfa93300 util/hexdump: Remove ascii parameter from qemu_hexdump_line 
Split out asciidump_line as a separate function, local to hexdump.c,
for use by qemu_hexdump.  Use "%-*s" to generate the alignment
between the hex and the ascii, rather than explicit spaces.

b42581f5bb util/hexdump: Reorder qemu_hexdump() arguments 
qemu_hexdump()'s pointer to the buffer and length of the
buffer are closely related arguments but are widely separated
in the argument list order (also, the format of <stdio.h>
function prototypes is usually to have the FILE* argument
coming first).

Reorder the arguments as "fp, prefix, buf, size" which is
more logical.

67263b33af util/hexdump: Convert to take a void pointer argument 
Most uses of qemu_hexdump() do not take an array of char
as input, forcing use of cast. Since we can use this
helper to dump any kind of buffer, use a pointer to void
argument instead.

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
