interface the module was compiled with. The #define YASM_module_VERSION
should be incremented on every functional change to the module interface.

differentiate e.g. AMD64 from x86. Doesn't prohibit anything in x86 yet,
but does standardize unsupported warnings across objfmts (most objfmts will
not support all machines and/or all architectures).

use of configure.ac's --enable-warnerror, which was set up to disable
conversion errors due to flex's warning-prone generated code. As we no
longer use flex, fix configure.ac to not disable conversion errors.

- Switch to bit-based output, including shift capability
- This means the standard intnum output functions can be used for non-byte
oriented archs like LC-3b (implemented)
- Default out of range (overflow) warnings for intnum (bugzilla bug 14)
- Change floating point overflow/underflow errors to warnings
To do (hooks but not implemented):
- Shifting floatnums into destination
- Floatnum destinations larger than floatnum value
- Big endian support for intnum and floatnum
Related simultaneous changes:
- Use bc instead of ep in objfmt output_expr() functions; while bc->line
should == (*ep)->line, in case they differ, we want to use the bc->line
so as not to confuse users.
- lc3b-mp22NC test was not properly offsetting the accessed variables, but
since the variable "sections" started at an aligned offset, the output
was actually correct. The new intnum warnings uncovered this issue, so
fix code to be correct (and not generate warnings).

expression line number instead of the start line number (which may be 0,
which isn't nearly as useful as the expression line number).

ELF objfmt implementation.
Assumed to be correct for the test cases, but only tested as far as feasible.
Currently only implements 32bit 386 little-endian, but is mostly abstracted
well enough to easily add more machines.

intnum folding on and leveling performed would result in terms getting copied

- Up internal format size to 128 bit.
- Use full internal format size for all calculations.
- Always store negative numbers using full internal size
(avoids 0xffffffff == -1?? issue)
This fixes many inconsistencies in handling of >32-bit intnums.

Test also found a bug in COFF parsing of section options; this will be fixed
and a separate test added explicitly for it.

- Move config.h and util.h from libyasm (and installed libyasm) to top level.
- Move yasm_* functions from util.h to coretype.h.
- Remove a number of autoconf-related YASM_*_INTERNAL options from libyasm.h.
- Rename YASM_INTERNAL to YASM_LIB_INTERNAL; it now actually means what the
comment describes: enables definitions that violate the yasm_* namespace.
While we're at it, no longer define YASM_LIB_INTERNAL from yasm frontend, so
it's closer to what a real typical libyasm-using application would look like.

pathname changing issues when builddir != srcdir (previous workaround worked
for text files, but for more complex objfmts such as coff that embed the source
