The idea of putting the warnings in the source code was a nice one,
really, but it ended up being a nightmare from the perspective of
build dependencies. Disaggregate them, and tweak the documentation for
easier reading.

SPDX is an international standard for documenting software license
requirements. Remove the existing headers and replace with a brief
SPDX preamble.
See: https://spdx.dev/use/specifications/
The script used to convert the files is added to "tools", and the
file header templates in headers/ are updated.

Convenience preprocessor functions that allows for efficient packing
of binary data in source code.
Move some functions that has previously been local but are more
generally useful into more accessible places.

Micro-optimize the set_bit() function. Using size_t (in particular,
using an unsigned type) produces better code.

Support generating bfloat16 constants. This is a bit awkward, as "DW"
already generates IEEE half precision constants; therefore there is no
longer a single floating-point format for each size. This requires
some replumbing.
Fortunately bfloat16 fits in 64 bits, so support generating them with
a macro that uses __?bfloat16?__() to convert to integers first before
passing them to DW.

Haiku apparently wants to include <float.h> rather than
"float.h". Rename float.[ch] to floats.[ch] to avoid unnecessary
namespace confusion.
