The slirp code does not use index() and gethostid() anymore,
so these parts can be removed without problems.
memmove() and strerror() should be available on each of the
supported platforms nowadays, too, so these wrappers are also
not needed anymore.
And we certainly also do not support Ultrix anymore, so no
need to keep the code for this platform anymore.

There are a lot of unused #defines / #undefs in slirp_config.h,
which are apparently left-overs from the very early slirp code.
Since there is no more code that uses them, let's simply remove
them from our version of slirp.

Here we don't check the return value of malloc() which may fail.
Use the g_new() instead, which will abort the program when
there is not enough memory.

Also, use g_strdup instead of strdup and remove the unnecessary
strdup function.

Neither DECLARE_SPRINTF nor BAD_SPRINTF are needed for QEMU.

QEMU won't support systems with missing or bad declarations
for sprintf. The unused code was detected while looking for
functions with missing format checking. Instead of adding
GCC_FMT_ATTR, the unused code was removed.

There is no need to have a second set of integral types.
Replace them by the standard types from stdint.h.

Calling gettimeofday() to compute a time interval can cause problems if
the system clock jumps forwards or backwards; replace updtime() with
qemu_get_clock(rt_clock), which calls clock_gettime(CLOCK_MONOTONIC) if
it is available.

Also remove some useless macros.

The UDP emulation code for talk has been commented out since the
beginning of time, and unless someone who runs CU-SeeMe on qemu with
user-mode networking can vouch that the special magic (a) is necessary
and (b) works, let's get rid of the code.
