The -Ov option is useful but was undocumented.
Add an initialization to keep gcc from complaining at optimization
level -Og.

For debugging preprocessed code, it is useful to be able to ignore
%line directives rather than having to filter them out externally.

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.

-E -MD should work and output a dependency file.
-MD can be used without a filename; there is a default filename or
-\c{-MF} can be used.

There are probably other corner cases where we could at the very
least produce an incorrectly rounded result, so be a bit more cagey
about the description of the bug.

BR 3392527: make sure that all command-line specified preprocessing
directives are processed after the system-generated ones. In
particular __OUTPUT_FORMAT__ was generated after command line pass 2,
at which point -p, -d, -u, --pragma and --before had already been
processed.
There is no reason to split up defined_macros() anymore: the right
place to execute it is simply between command line passes 1 and 2. We
can also set dfmt here, which lets us define a __DEBUG_FORMAT__ macro
as well.
Finally move some options that have no business being processed in
pass 2 to pass 1.

-dSAFER seems to break font integration on some systems. Furthermore,
once given -dSAFER seems to not be possible to override, so instead of
calling via the ps2pdf script, call GhostScript explicitly with the
equivalent options, sans -dSAFER.

While today's manual lists "text" as the code section name,
"code" has been effectively named from d1da074.

While configuring optimization in a level is conventional,
a certain optimization tends to conflict with some pragma.
For example, jump match conflicts with Mach-O's
"subsections-via-symbols" macro.
This configurability will workaround such conflicts.
