- 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).

three possible return states (okay, invalid, or indeterminate). Propagate
this return change into the yasm_x86__expr_checkea() call tree as necessary.

internal errors, and mis-optimization as seen in Bugzilla Bug 13.
Reported by: meor@softhome.net
Fix a few minor bugs (not heavily tested) due to use of opersize == 32 as a
comparison; this fails when opersize == 64 due to bits = 64, but the default
size is still 4 bytes, not 2.
There's still a couple cases here where we might end up with internal errors
due to a lack of variety in return values; I'll fix those in the next commit.

problem, adding this required adding some fields to x86_jmprel (now a
misnomer, as FAR jumps are absolute) to save the far opcode, and additional
support in libyasm's yasm_expr_* to properly handle the YASM_EXPR_SEGOFF
operator.

- 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
filename in the binary output file, we need to find a different way).
