Rename the "headers" directory to "templates", and rename the files
within as template.* with the appropriate file types so that editors
will pick up the correct type. Add a .h file template.

The C++-style cast-to-bool hack was broken in concept that it doesn't help the
fundamental problem -- implicit conversions are broken for the
backwards compatibility enum definition -- as well as in
implementation, as it misspelled __STDC_VERSION__ as __STDC_VERSION.
The #ifdef bool test *should* have prevented this problem, but
apparently several compilers do define "bool" in <stdbool.h> even when
it is a keyword, in violation of the C23 spec.

Improve the byte code reference documentation to make a few opcodes
more clear and add some general properties about the byte codes,
including the files that need to be changed when the byte code
changes.

If the assembly stops after the first pass, only active_list_options
will be seen; this is also the value that applies for local changes in
the list options. Thus, both variables need to be tweaked.

`a || b` only evaluates b if a is false. `a | b` always evaluates
both a and b. If a and b are of type bool, || is usually what you
want, so clang now warns on `|` where both arguments are of type bool.
This warning fires once in nasm. It looks like `|` is an (inconsequential)
typo of `||`, so use that instead.
No intended behavior change.
Not all registers are valid as memory references, and thus
using RM_ZERO is incorrect. Use RN_ZERO instead, which is simply the
zero-register bit.

Open Watcom does not support 64-bit constants at 'case'.
[ hpa: I'm pulling this, but I'm really, *really* questioning its
supportability long term. The OpenWatcom people need to fix this, or
we are just going to have to say "OW is not supported."
At some point we *are* going to move to a "C99 is baseline" policy for
code; there are simply too many features in C99 that are actively
painful to be without.
That is, unless we decide to go to C++, which is under consideration
but is a much bigger job. In that case, the target will probably be
either C++11 or C++14 as those C++ versions contain some pretty
essential features. ]

Similar to PCOMMIT, they are tagged as 'NEVER'
