Remove copyright strings ifdef'd out

We've ifdef'd out the copyright strings for some time now. Go ahead and
remove the ifdefs. Plus whatever other detritis was left over from other
recent removals. These copyright strings are present in the comments and
are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

General 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.

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Add missing static qualifiers

Put some static keywords in the source code.

For these simple utilities, it doesn't harm to make all global variables
static. In fact, this allows the compiler to perform better forms of
optimisation and analysis.

is a two-module system, consisting of a base compute module and a

platform to test CPU affinity and NUMA-aware features in FreeBSD.

Fix a bug introduced in rev.1.23 - for some reason mkdir("/", ...) system

fix number of ports, that often call `mkdir -p //usr/local/foobar'. This

mkdir("/", ...) or fix VFS code to return consistent errno for this case.

Honour the spirit rather than the implementation of the previous changes;
if we are invoked with -m, use chmod() on the final directory component
in order to ensure the mode is correctly set.

Make this compile, and honour the spirit of the original design while

correct use of .Nm. Add rcsid.

Fix several problems with mkdir:

1) Fix mkdir -p to exit with the proper exit status and issue an error
message if it was unable to create all of the specified directories
and they did not previously exist. POSIX says:

The mkdir utility shall exit with one of the following values:

0 All the specified directories were created successfully or the
-p option was specified and all the specified directories now
exist.

E.g.

% mkdir -p /var/mkdir
mkdir: /var/mkdir: Permission denied

% touch /tmp/file
% mkdir -p /tmp/file/dir
mkdir: /tmp/file: Not a directory

Previously the above examples would exit with a zero exit status
and no error message. Something like the following run as a
normal user will still not produce an error:

% id
uid=629(mpp) gid=629(mpp)....
% mkdir -p /usr/local/etc
% ls -ld /usr/local/etc
drwxr-xr-x 4 bin bin 512 Dec 26 14:55 /usr/local/etc/

2) Cleaned up the mode handling to be more efficient when multiple
directories are being created.

3) Fixed a problem where directories could be created with the wrong mode
if the the -p option was specified and the build() routine returned
and error. It would leave the umask set incorrectly at this point.

4) Removed an unused variable.

Closes PR# 2304.

[ From Dave Tweten ]

POSIX.2 looks pretty unequivocal to me, and it agrees with you.

Under the explanation of the "-p" option, it says, "Each dir operand that
names an existing directory shall be ignored without error." Under the
explanation of exit status zero, it says, "All the specified directories were
created successfully, or the-p option was specified and all the specified
directories now exist."

Seems to me POSIX requires exactly the behavior you want.

[ And I've made the change, which is also now compatible with 1.x - jkh ]
