71ec05a212 sort: Cache value of MB_CUR_MAX
Every usage of MB_CUR_MAX results in a call to __mb_cur_max.  This is
inefficient and redundant.  Caching the value of MB_CUR_MAX in a global
variable removes these calls and speeds up the runtime of sort.  For
numeric sorting, runtime is almost halved in some tests.

1de7b4b805 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.

2ac58c1d79 In usr.bin/sort, use another method of silencing warnings about unused
arguments, which does not trigger self-assignment warnings in certain
circumstances (for example, using clang with ccache).

c66bbc9143 Add a BSD-licensed sort rewrite that was started by me and later completed
with the major functionality and optimizations by Oleg Moskalenko.
It is compatible with the latest version of POSIX and the current GNU sort
version that we have in base.  Beside this, it implements all the
functionality introduced in later versions of GNU sort.  For now, it will
be installed as "bsdsort", keeping GNU sort as the default sort
implementation.
