libc: export pthread_getname_np stub

pthread_getname_np needs to be provided by libc in order to import
jemalloc 5.3.0.

A stub implementation for libc pthread_getname_np() is added for
_pthread_stubs.c, which always reports empty name for the main thread.

Internal _pthread_getname_np() is not exported, but provided for libc
own use.

General 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.

Simplify code by replacing _thr_ref_add() with _thr_find_thread().

If a thread who's name is being set is not the current thread, use macros
