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.

Only activate __EXT1_VISIBLE block when using sys/errno.h in userspace.

The prerequisite for '#if __EXT1_VISIBLE' functionality is the
inclusion of sys/cdefs.h. errno.h only auto-includes the header for
non-kernel environment, and EXT1 block only useful for non-kernel as
well.

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,
192.168.1.1, with share "share". This commit fixes a problem
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.

Add some missing errnos from POSIX. Nothing in FreeBSD generates
these at the moment, but applications that test for them will now
have a better chance of compiling.

I have intentionally omitted errnos that are only good for STREAMS,
since apps that use STREAMS won't compile anyway. The exception is
EPROTO, which was apparently intended for STREAMS, but worth having
anyway because Linux (mis)uses it for other things.

Copyin and copyout are only possible from a process-native thread,
and therefore we need a way for ioctl handlers to run in that thread
in GEOM. Rather than invent a complicated registration system to
recognize which ioctl handler to use for a given ioctl, we still
schedule all ioctls down the tree as bio transactions but add a
special return code that means "call me directly" and have the
geom_dev layer do that.

Use this for all ioctls that make it as far as a diskdriver to
avoid any backwards compatibility problems.
