Hijack utimensat(2) so that t_vfs test passes after cp(1)/mv(1) are
changed to use the system call. Linux also has this system call, but
not tested this on linux.

Use autoconf for rump kernel posix hypercall layer.

This gets rid of homegrown hacks and puts all probes in one place.

Tested for NetBSD (build.sh + anita) and Linux (buildrump.sh)

fdoff, and was exposed >3 years after writing the test when rump kernels
started providing fd's 0/1/2)

Ignore the contents of revents when poll() returns failure.
This is one more part to the fix for PR kern/46464. Patch
from pooka.

Do not assert that the two threads do not simultanously notify each
other, because sometimes they do. Should fix PR kern/46464. OK pooka.

Add Android support for rump kernel.

Extend #undef _FORTIFY_SOURCE to both files to avoid compiler

Support Linuxen where libc ioctl has cmd as int unstead of unsigned long.

sys/cdefs.h should come from rumpuser_port.h

Noticed by Justin Cormack while building against musl libc.

* avoid problems if the platform calls readlink() from dlsym()
* alias __read_chk() to read() on Linux (technically, though,
it should call host __read_chk() instead of read())

When emulating poll/select better tell the events of the host kernel
apart from those received from the rump kernel. Also handle timeout.

Change the syscall API for quotas over to the new non-proplib one.

- struct vfs_quotactl_args -> struct quotactl_args
- add sys/stdint.h to sys/quotactl.h for clean userland build
- install sys/quotactl.h in /usr/include
- update set lists for same
- add new marshalling code in libquota
- add new unmarshalling code in vfs_syscalls.c
- discard proplib interpreter code in vfs_quotactl.c
- add dispatching code for the 14 quotactl ops in vfs_quotactl.c
- mark the proplib quotactl syscall obsolete
- add a new syscall number for the new quotactl syscall
- change the name of the syscall to __quotactl()
- remove the decl of the old quotactl from quota/quotaprop.h
- add a decl of the new quotactl to sys/quotactl.h
- update the libc build
- update ktruss
- remove proplib marshalling code from libquota
- update copy of syscall table in gdb ppc sources
- hack rumphijack to accomodate new quotactl name (as I recall,
pooka wanted such a name change to simplify something, but I
don't really see what/how)

This change appears to require a kernel version bump for rumpish
reasons.

Disable Fortification for pthread and rump stubs.

Backout previous, it breaks lots of tests (tests/lib/librumphijack for
example).

Move the forward declaration of _sys_readlink() outside of the #if,
so that the build succeeds even if _FORTIFY_SOURCE isn't > 0.
