Added 3 new errno values, requred by various standards: EOVERFLOW,
ECANCELED, EILSEQ.

Fixed ibcs2 and especially linux EIDRM and ENOMSG errno mapping.

Make errno finally and permanently thread-aware so that it is no longer
necessary to compile with _THREAD_SAFE defined. This means that people
will get thread-aware code whether they like it or not. This change
is required to allow a process to link against libpthread and libc
to use kernel threads (and prevent each thread from clobbering another
thread's errno just be doing a syscall).

This is bound to break some ports, but it is strictly allowed by ANSI C,
so anything that breaks as a result was already broken anyway 8-).

Add EIDRM errno (PR 176), ENOMSG errno (myself) for prober sysv_ipc.

Added a kernel-only error code ENOICTL. This will be returned from
low level ioctl routines instead of the magic number -1 so that
callers can distinguish it from ERESTART (which happens to be -1).

Added a kernel-only error code ENOICTL. This will be returned from
low level ioctl routines instead of the magic number -1 so that
callers can distinguish it from ERESTART (which happens to be -1).
-1 meant that the ioctl was not handled at the called level.
ERESTART is normal when a sleeping ioctl is interrupted. ERESTART
got converted to ENOTTY instead of restarting the ioctl. Many
(most?) ioctls can not be restarted safely, but this is apparently
supposed to be handled by drivers converting ERESTART to EINTR.
I first saw this problem for TIOCDRAIN. Justin saw if for disk
ioctls.

Added missing parentheses.

Create new EINTEGRITY error with message "Integrity check failed".

An integrity check such as a check-hash or a cross-correlation failed.
The integrity error falls between EINVAL that identifies errors in
parameters to a system call and EIO that identifies errors with the
underlying storage media. EINTEGRITY is typically raised by intermediate
kernel layers such as a filesystem or an in-kernel GEOM subsystem when
they detect inconsistencies. Uses include allowing the mount(8) command
to return a different exit value to automate the running of fsck(8)
during a system boot.

These changes make no use of the new error, they just add it. Later
commits will be made for the use of the new error number and it will
be added to additional manual pages as appropriate.

sys: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Expose kernel-only errno values if _WANT_KERNEL_ERRNO is defined.

The kernel uses a few negative errno values for internal conditions
such as requesting a system call restart. Normally these errno values
are not exposed to userland. However, kdump needs access to these
values as some of then can be present in a ktrace system call return
record. Previously kdump was defining _KERNEL to gain access to ehse
values, but was then having to manually declare 'errno' (and doing it
incorrectly). Now, kdump uses _WANT_KERNEL_ERRNO instead of _KERNEL
and uses the system-provided declaration of errno.

Fix autofs triggering problem. Assume you have an NFS server,

where "mkdir /net/192.168.1.1/share/meh" would return spurious
error instead of creating the directory if the target filesystem
wasn't mounted yet; subsequent attempts would work correctly.

The failure scenario is kind of complicated to explain, but it all
boils down to calling VOP_MKDIR() for the target filesystem (NFS)
with wrong dvp - the autofs vnode instead of the filesystem root
mounted over it.
