Remove $FreeBSD$: two-line .h pattern

Remove /^\s*\*\n \*\s+\$FreeBSD\$$\n/

Allocate extra inodes in makefs when leaving free space in UFS images.

By default, makefs(8) has very few spare inodes in its output images,
which is fine for static filesystems, but not so great for VM images
where many more files will be added. Make makefs(8) use the same
default settings as newfs(8) when creating images with free space --
there isn't much point to leaving free space on the image if you
can't put files there. If no free space is requested, use current
behavior of a minimal number of available inodes.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

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.

No functional change intended.

makefs: sync NetBSD IDs with upstream for changes that we already have

May 22 21:51:39 2011 +0000 (christos):

From Nathan Whitehorn (nwhitehorn at freebsd dot org):
Add code to generate bootable ISOs on Powermac and CHRP systems.
Synthesize some partition maps (APM and MBR, respectively) pointing
to (a) the whole disk, and (b) relevant El Torito boot images that
have been added by other code. These partition maps are a little
bit funny looking, but they seem to work. FreeBSD has been using
this successfully in their release generation on powerpc, as well
as generating all non-SPARC install media. SPARC support could
probably be added as an extension of this patch.

PR/45285: Martin Matuska: makefs does not properly convert ISO level 1 and 2
filenames (buffer overflow)

makefs does not properly verify the maximum filename length in the
special "." case for both ISO level 1 and ISO level 2 filename
conversion. This creates broken images or causes a buffer overflow
(ISO level 2).

ISO level 1:
If a filename contains only dots or up to 8 characters followed by
dots the 8+3 limit check doesn't work.

ISO level 2:
If a filename contains a dot in the first 30 characters and a dot
on the 30th character, the length limit check doesn't work and the
buffer is overflowed.
