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.

As xprintf has not kept up with our standard printf(3) implementation,
it is becoming increasingly dangerous to continue to allow it to take

printf(): Save errno earlier.

The manual page says %m is replaced with “the string representation of
the error code stored in the errno variable at the beginning of the
call”. However, we don't actually save `errno` until fairly late in
`__vfprintf()`. Make sure it is saved before we do anything that
might perturb `errno`.

__vprintf(): switch from strerror() to strerror_rl()

This eliminates the use of non-thread-safe function in printf*() family,
and make the call locale-aware. Also, it stops obliterating the
strerror() static buffer, which aligns with the POSIX requirement that
implementations must behave as if no standard-mandated functions call
strerror().

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.
