ar: shuffle symbol offsets during conversion for 32-bit ar archives

During processing we maintain symbol offsets in the 64-bit s_so array,
and when writing the archive convert to 32-bit if no offsets are greater
than 4GB. However, this was somewhat inefficient as we looped over the
array twice: first, converting to big endian and second, writing each
32-bit value one at a time (and incorrectly so on big-endian platforms).

Instead, when writing a 32-bit archive shuffle convert symbol data to
big endian (as required by the ar format) and shuffle to the beginning
of the allocation at the same time.

Also correct emission of the symbol count on big endian platforms.

Further changes are planned, but this should fix powerpc64.

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.
