With -Lb, it is possible that we don't have a filename for the current
code expansion. In that case, suppress calling dfmt->linenum as some
debug backends *really* aren't equipped to handle that case.

If the segment number changes, we also need to invoke dfmt->linenum(),
as a .nolist macro may end up emitting to more than one section.
This also adds the source location explicitly to the output data
structure; the cost for that is minimal, and will enable a more
sophisticated debug backend to receive the entire data structure in
the future.

If -std=c17 and -std=c11 don't work, try -std=c99 as well.
-std=c90 is unlikely to work because of the requirement for "long
long" on L32 platforms, which isn't likely to be supported on a pure
C90 compiler.

If the compiler supports it, use -std=c17 or -std=c11. Hopefully, this

list_reverse() used "next" as an argument, while also needing to
refer to the structure field "next". Furthermore, the two temp
variables can be made generic by making them void *, and as this is
not a loop construct this is doable by declaring them inside the macro
loop.

Sometimes we want to search for an exact key only, and reject the case

Add operations to get the first and last entry in the tree,
respectively. Searching for 0 or ~UINT64_C(0) is not sufficient in the
presence of duplicated keys, and is more inefficient anyway.
rb_first() followed by rb_next() until NULL, or equivalently rb_last()
followed by rb_prev() until NULL, can be used to walk the tree in key
order (ascending or descending), including all duplicate key
entries.
Since this is a *threaded* tree now, this walk can safely free entires
as it goes along, as long as the whole tree is destroyed; once any one
entry has been freed, the tree is no longer valid for anything other
than proceeding with the same tree walk.

Change the left-leaning red-black (LLRB) trees into left-leaning
threaded red-black trees. Instead of NULL pointers at leaf nodes, use
the otherwise unused field as a pointer to the lexical predecessor
(left) or successor (right). This allows fast previous/next
interator operation without needing to keep track of the root of the
tree at all times.
The additional metadata that needs to be kept can be done for "free"
simply by changing "bool red" into a flag field.

NASM would incorrectly only allow for the alignment to be increased,
even when overridden by the user. Allow the user to specify any
alignment value and have it override the partition type default.
The user can increade their own alignment value specification later,
of course, and the sectalign directive will present a floor for either
kind of specification.

The clang behavior is sometimes really weird, and extremely hard to
debug, when uninitialized variables are used even if the value cancels
out in an expression. It also depends on optimization level, etc.
-ftrivial-auto-var-init=zero makes the behavior
predictable. Unfortunately it also needs a really weird "enable"
option, and it issues a warning about an unused command line option on
link, which may get promoted to error, so silence the warning before
doing anything else.

1. Error messages would issue with the line number of %endrep.
2. Debug line information would ignore both macros and reps.
This is doubly wrong; macros are semantically equivalent to
inline functions, and it is expected that debuggers trace
into these functions.
These changes finishes the last parts of moving all responsibility for
the listing enable/disable into the preprocessor, so remove the
way over-complicated macro inhibit facility from the listing module
entirely.
