<libutil.h> and <util.h> on *BSD (some have one, some another)
were #included just for openpty() declaration. The only file
where this function is actually used is qemu-char.c.
In vl.c and net/tap-bsd.c, none of functions declared in libutil.h
(login logout logwtmp timdomain openpty forkpty uu_lock realhostname
fparseln and a few others depending on version) are used.
Initially the code which is currently in qemu-char.c was in vl.c,
it has been removed into separate file in commit 0e82f34d077dc2542
Fri Oct 31 18:44:40 2008, but the #includes were left in vl.c.
So with vl.c, we just remove includes - libutil.h, util.h and
pty.h (which declares only openpty() and forkpty()) from there.
The code in net/tap-bsd.c, which come from net/tap.c, had this

net: split all the tap code out into net/tap.c
Note this commit not only moved stuff out of net.c to net/tap.c,
but also rewrote large portions of the tap code, and added these
completely unnecessary #includes -- as usual, I question why such
a misleading commit messages are allowed.
Again, no functions defined in libutil.h or util.h on *BSD are
used by neither net/tap.c nor net/tap-bsd.c. Removing them.
And finally, the only real user for these #includes, qemu-char.c,
which actually uses openpty(). There, the #ifdef logic is wrong.
A GLIBC-based system has <pty.h>, even if it is a variant of *BSD.
So __GLIBC__ should be checked first, and instead of trying to
include <libutil.h> or <util.h>, we include <pty.h>. If it is not
GLIBC-based, we check for variations between <*util.h> as before.
This patch fixes build of qemu 1.1 on Debian/kFreebsd (well, one
of the two problems): it is a distribution with a FreeBSD kernel,
so it #defines at least __FreeBSD_kernel__, but since it is based
on GLIBC, it has <pty.h>, but current version does not have neither
<util.h> nor <libutil.h>, which the code tries to include 3 times
but uses only once.

If neither of __FreeBSD__, __FreeBSD_kernel__ and __DragonFly__ is defined,
util.h is included from tap-bsd.c.
Don't include it again if __OpenBSD__ is defined.

error_report() terminates the message with a newline. Strip it it
from its arguments.
This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for
IFF_VNET_HDR available" (all three versions).
There's one place that passes arguments without newlines
intentionally: load_vmstate(). Fix it up.

Handle ifname on FreeBSD hosts; if no ifname is given, always start
the search from tap0. (Simplified/cleaned up version of what has been
in the FreeBSD ports for a long time.)

net/tap-bsd.c was assuming IFF_VNET_HDR was always available, which
I think isn't true on any BSD.

Currently compiling the tap sources breaks on Mac OS X. This is because of:
1) tap-linux.h requiring Linux includes
2) typos
3) missing #includes
This patch adds what's necessary to compile tap happily on Mac OS X.
I haven't tested if using tap actually works, but I don't think that's a
major issue as that code was probably seriously untested before already.
I didn't split the patch, because it's only a few lines of code and
splitting is probably not worth the effort here.
