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.

Invoke the dirname() function in a POSIX compliant way.

POSIX requires that the argument of dirname() is of type "char *". In
other words, the input buffer can be modified by the function to store
the directory name.

Pull a copy of the string before calling dirname(). We don't care about
freeing up the memory afterwards, as this is done at the very bottom of
main(), right before the program terminates.

Remove O_SYNC from the options passed to dbmopen().

The services db is created as a temporary file that is moved over the
existing file after completion. Thus there is no need to immediately
flush all created db records to the temporary file.

This speeds up creation of the services db by a factor of 500 on my
ZFS based /var/db filesytem (from 110 seconds to 0.235 seconds).

Make cap_mkdb and services_mkdb file operations sync

Similar fix was done for passwd and group operations in r285050. When a
temporary file is created and then renamed to replace official file there
are no checks to make sure data was written to disk and if a power cycle
happens at this time, system can end up with a 0 length file
