libc: drop NO_FP_LIBC support

NO_FP_LIBC was added in 2004 to save space by disabling FP support in
*printf()/*scanf(). The size benefit is negligible on modern systems
and conflicts with assumptions made by current base utilities.

Remove the option and always build libc with floating-point support.

The function fwscanf() return value is wrong when encountering an early
matching failure.

According to the Open Group documentation for fwscanf:
"Upon successful completion, these functions shall return the number of
successfully matched and assigned input items; this number can be zero in
the event of an early matching failure."

Without this change, fwscanf would return EOF in the case of an early
matching failure, instead of the proper return value of 0.

This change aligns fwscanf(3) with the implementation in fscanf(3).

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.
