cd9660: replace bcopy/bzero with C standard equivalents

To reduce diffs against NetBSD.

Unsign some values related to allocation.

When allocating memory through malloc(9), we always expect the amount of
memory requested to be unsigned as a negative value would either stand for
an error or an overflow.
Unsign some values, found when considering the use of mallocarray(9), to
avoid unnecessary casting. Also consider that indexes should be of
at least the same size/type as the upper limit they pretend to index.

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.

Handle _PC_FILESIZEBITS and _PC_SYMLINK_MAX pathconf() requests in cd9660.

cd9660 only supports symlinks with Rock Ridge extensions, so
_PC_SYMLINK_MAX is conditional on Rock Ridge.

Consistently use vop_stdpathconf() for default pathconf values.

Update filesystems not currently using vop_stdpathconf() in pathconf
VOPs to use vop_stdpathconf() for any configuration variables that do
not have filesystem-specific values. vop_stdpathconf() is used for
variables that have system-wide settings as well as providing default
values for some values based on system limits. Filesystems can still
explicitly override individual settings.

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.

Do not access buffer if bread(9) or cluster_read(9) failed. On error,
the functions free the buffer and set the pointer to NULL. Also
remove useless call to brelse(9) on the error path.
