When a section other than .text has a start < origin, we would
segfault; fix that.
Furthermore, at bin_cleanup() we don't have usable file/line
information, so pass ERR_NOFILE to the error() function. Perhaps less
than ideal, but better than printing a null pointer.
Add a common file, outlib.c, for output formats. Add the function
realsize() instead of open-coded variants in almost every backend.

The "bin" format was misinterpreting the overloading of the "size"
argument to out(), which caused another source of 64-bit relative
offset errors.

ctype functions take an *int*, which the user is expected to have
taken the input character from getc() and friends, or taken a
character and cast it to (unsigned char).
We don't care about EOF (-1), so use macros that cast to (unsigned
char) for us.
Move the handling of "extra" macros (i.e. output format macros) into
the macros.pl mechanism. This allows us to change the format of the
internal macro store in the future - e.g. to a single byte store
without redundant pointers.
Also, stop using indicies into a long array when there is no good
reason to not just use different arrays.
Fix one missed change from "type" to "size". May want to look through
all the other backends as well for similar issues.
This would generate the wrong section lengths, with obviously bad results.
Address data is always int64_t even if the size itself is smaller;
this was broken on bigendian hosts (still need testing!)
Create simple "write sized object" macros.
Don't combine type and size into a single argument; *every* backend
immediately breaks them apart, so it's really just a huge waste of
effort. Additionally, it avoids using short immediates in the
resulting code, which is a bad thing.
Proper use of bool and enum makes code easier to debug. Do more of
it. In particular, we really should stomp out any residual uses of
magic constants that aren't enums or, in some cases, even #defines.
Concentrate compiler dependencies to compiler.h; make sure compiler.h
is included first in every .c file (since some prototypes may depend
on the presence of feature request macros.)
Actually use the conditional inclusion of various functions (totally
broken in previous releases.)
Minor fixes to make it possible to compile with MS Visual C++ 2005.
Unfortunately, MSVC++ is not fully C99 compliant; in particular, it
doesn't handle interspersed declarations and other code. Furthermore,
it chokes on some expressions in outelf64.c, which fortunately can be
easily substituted with simpler expressions.
Finish the perfect hash tokenizer, and actually enable it.
Move stdscan() et al to a separate file, since it's not needed in any
of the clients of nasmlib other than nasm itself.
Run make alldeps.
