Add the %map() function which can apply arguments to a macro from a
list.
Allow the user to specify the desired radix for an evaluated
parameter. It doesn't make any direct difference, but can be nice for
debugging or turning into strings.
As part of this, split expand_one_smacro() into two parts: parameter
parsing and macro expansion. This is a very straightforward splitting
of two mostly unrelated pieces of functionality.

The production "value := type value" was not correct; should have been
"type atom", which can be merged with the "atom" production to "[type]
atom".

%expr() was a pre-release development name for this function, however,
the released name is %eval().

The dependency on the warning files breaks when we are building in a
directory *and* the files already exist from being shipped with the
distribution tarballs. The make VPATH simply isn't sophisticated
enough to deal with it, so let the C compiler handle it by #including
the generated file from a dummy C file.

Add the option of having strings only conditionally quoted (&&) -- do
not quote an already quoted string again -- as opposed to always
quoting a string.
This makes a lot of the string functions way simpler to implement, and
removes the need to share ad hoc parsing code with directives.

Add the %abs() function, to produce the absolute value as an

Change the order of the arguments for %num().
Refactor the handling of optional arguments, to reduce the amount of

might be extended in the future.

Implement the %cond() and %sel() functions that expand to a specific

In some of the preprocessor function examples, actually enforce
equivalence by using %xdefine in the function examples so the

The use of statements like "chapter", "section" and so on makes the

Allow a single index entry key to be defined with \IR more than once,
generating multiple entries in the index; this is really useful for
example to always generate "macros, single-line" and "single-line
macros" entries sorted at different places.
Be smarter about sorting the index: sort (nearly) all special
characters before alphanumerics, and (attempt to) sort numbers in
numerical order rather than alphabetical (so BITS8 sorts before
BITS16).

If a list of index entries is so long that the whole list can't fit

There is no documentation of the `%unimacro` directive.
This is particularly confusing when you’re trying to remove a macro
that has previously been defined with the `%imacro` directive.
