Add a new %note directive to issue a note into the list file without
printing a message. The difference between %note and a comment is that
a %note will be issued with single-line macros expanded, and will be
issued even if it occurs inside a .nolist macro.

Right now it appears we lose more than one error message from the
listing file; this is not OK.
Add support for dropping the current listed line (leaving only
possible error messages.) This will be used in the upcoming %note
patch.

Add a default-off warning for phase error in pass 1. This is default
off because of the lateness in the release cycle, but cases where we
have such instability should be investigated further. For now, the
warning is here so we can debug these problems in the field.

We don't want to lose the offset into the parent section when we
create a subsection, at least not for the MachO backend which is
currently the only user of subsections. Allow ofmt->herelabel() to set
a flag to copy the section offset from the previous section.

We may not even have the most basic stabilization done unless we run
at least two optimization passes, e.g. in the case of subsections.
However, we cannot run more than one stabilization pass (pass0 == 1);
for one thing we'll call ofmt->symdef() multiple times on the same
symbol, which is not allowed. If we haven't achieved stability by the
time we decide to run a stabilization pass, plod on and hope for the
best.

Add PTWRITE instruction. It is worth noting that we should
be able to do "ptwrite [eax]" in 32-bit mode, but the instruction
selector doesn't currently handle that well in a way that doesn't make
64-bit mode very confusing.

We can be in absolute space and still end up with segment-relative

If we define a label which was previously declared EXTERN, then
automatically treat is as GLOBAL.
Previously, we would fail to converge and loop forever, which is
obviously not what we want. This is more user-friendly anyway.

..@ labels (macro-local) are NASM specials, although not "magic": they
are explicitly defined to not preturb the local label base name.
However, they return false for both islocal() and ismagic(), so we
need to add a new function containing the correct test for when the
local label base should be advanced.

1. The mkdep.pl program didn't handle excluded dependencies correctly,
causing it to error out due to config/config.h not existing.
2. NMAKE is sensitive to the order suffixes appear in .SUFFIXES,
causing it to try to use the builtin rule .c.exe instead of
.c.obj -> .obj.exe.
3. NMAKE doesn't handle the && operator between commands.
4. The !ifdef jungle around dependency generation was wrong.
