80c4f23c52 nasm_warnf() -> nasm_warn()
We want to strongly encourage writers of warnings to create warning
categories, so remove the flagless nasm_warn() and change nasm_warnf()
to nasm_warn().

723ab481a6 warnings: define warning classes at point of use
It is extremely desirable to allow the user fine-grained control of
warnings, but this has been complicated by the fact that a warning
class has had to be defined in no less than three places (error.h,
error.c, nasmdoc.src) before it can be used in source code. Instead,
use a script to define these via magic comments at the point of use.

This hopefully will encourage creating new classes as needed.

df4d342599 warnings: rename ERR_WARN_* to WARN_*
The prefix ERR_WARN_ is unnecessarily long and may be a disincentive
to create new warning categories. Change it to WARN_*, it is still
plenty distinctive.

This is equivalent to nasm-2.14.xx checkin 77f53ba6d4.

950dee9edc BR 3392535: warning on redefine, promote define-on-pass2 to error
If we redefine consistently, make it a suppressed-by-default warning.
If we end up doing the define on pass 2, promote that to a
default-error warning; using a default-error warning allows the user
to demote it should they so wish.

eb48c1191d warnings: make it possible for a warning to default to an error
This allows us to do soft-migration of warnings to errors; they will
now be nonfatal errors by default, but gives the user the option to
demote them.

93367ea97b warnings; move WARN_OTHER to the end; allow non-warnings to be suppressed
Putting WARN_OTHER at the end of the list creates a number of
advantages and simplifications:

1. It is more user friendly! It is far more of a logical location for
   the default case to be at the end of the printed list.
2. The value 0 can be used in a number of places to indicate a
   non-suppressible event. By having warning_state[0] always contain
   WARN_ST_ENABLED, we can always do the table lookup, even.
3. It means non-warnings (except fatal/panic) can now be conditioned
   on warning states. In those cases, WARN_*, including WARN_OTHER,
   can be added to the mask for any category. This is especially
   useful for notes.

The only downside is that we have to explicitly detect the case where
we have ERR_WARNING but no WARN_ flag. This is a trivial test.

d351efc97d error: add nasm_note() helper, clean up helper generation
It is fairly easy to more compactly create error helpers since we are
using preprocessor hacks anyway, so do exactly that.

Create nasm_note() helpers for the new NOTE severity class.

b45c03ab42 asm: add a default-off warning for phase error in pass 1
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.

c51369067c errors: simplify nasm_fatal() and nasm_panic()
Nearly all instances of nasm_fatal() and nasm_panic() take a flags
argument of zero. Simplify the code by making nasm_fatal and
nasm_panic default to no flags, and add an alternate version if flags
really are desired. This also means that every call site doesn't have
to initialize a zero argument.

Furthermore, ERR_NOFILE is now often not necessary, as the error code
will no longer cause a null reference if there is no current
file. Therefore, we can remove many instances of ERR_NOFILE which only
deprives the user of information.

b2047cbb98 Make -Werror controllable on a per-warning-class basis
Make -Werror possible to control on a per-warning-class basis.  While
I was fixing up that code anyway, merge the handling of the -w, -W and
[warning] argument and directives.

Furthermore, make *all* warnings suppressible; any warning that isn't
categorized now belong to category "other".  However, for cleanliness
sake an "other" option does not get listed in the warning messages.
