changing soon, so fix it then.

Revamp intnum internals:
- 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.

Clean up and simplify libyasm.h options and symbol visibility:
- 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.

Change how bytecode and section lists are allocated. When YASM_INTERNAL is not
defined, the structures for the list heads are not defined, so the existing
yasm_bcs_initialize() and yasm_sections_initialize() were impossible to use.
Instead, rename these functions to yasm_bcs_new() and yasm_sections_new() and
make them allocate the space internally. Update yasm_bcs_delete() and
yasm_sections_delete() to free the internally-allocated space.

Use system includes instead of local includes. This allows replacement of

one), and is also more correct in general.
