lib/libc/string/ffs*.c: work around gcc warning

Gcc warns of infinite recursion if we use __builtin_ffs*() to
implement ffs*(). This is because gcc uses ffs() to implement
these on some platforms. Sidestep the warning by using
__builtin_ctz*() for these.

lib/libc/string: replace ffs/fls implementations with clang builtins

Most architectures we support (except for riscv64) have instructions
to compute these functions very quickly. Replace old code with the
ffs and clz builtin functions, allowing clang to generate good code
for all architectures.

As a consequence, toss out arm and i386 ffs() implementations.

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.
