The 4.2 sigreturn was a bit of a enima so the 4.2 was remove. Regenerate
to cope the very minor changes in comments and one string.

It is best for auditing of syscalls.master if we only append to the
file. Reserving unimplemented system call numbers for local use makes
this policy and provides a large set of syscall numbers FreeBSD
derivatives can use without risk of conflict.

We have not been able to run binaries from other BSDs well over a
decade. There is no need to document their allocation decisions here.
We also don't need to reserve syscall numbers of never-implemented
syscalls.

Previously userspace would issue one syscall to resolve the sysctl and then
another one to actually use it. Do it all in one trip.
Fallback is provided in case newer libc happens to be running on an older
kernel.

jails since FreeBSD 7.
Along with the system call, put the various security.jail.allow_foo and
security.jail.foo_allowed sysctls partly under COMPAT_FREEBSD11 (or
BURN_BRIDGES). These sysctls had two disparate uses: on the system side,
they were global permissions for jails created via jail(2) which lacked
fine-grained permission controls; inside a jail, they're read-only
descriptions of what the current jail is allowed to do. The first use
is obsolete along with jail(2), but keep them for the second-read-only use.

Mark the pipe() system call as COMPAT10.
As of r302092 libc uses pipe2() with a zero flags value instead of pipe().
