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.

Trivial arithmetic can be used for emitting the nibbles,
rather than full-blown printf formatting.

sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1.
Extract common code from reinitialize_rng_seed and load_kernel
to rng_seed_hex_new. Using qemu_hexdump_line both fixes the
deprecation warning and simplifies the code base.

sprintf() is deprecated on Darwin since macOS 13.0 / XCode 14.1.
Using qemu_hexdump_line both fixes the deprecation warning and
simplifies the code base.
Note that this drops the "0x" prefix to every byte, which should
be of no consequence to tracing.
