Push version numbers up to 1.00. This is just intended to reflect
...
that the BTX code can be regarded as stable: there are no associated
code changes.

Ignore, rather than emulate, an i386 'hlt' instruction (though for
...
most practical purposes, this should be indistinguishable from a
more strictly correct approach).

Make the BTX loader much more quiet about what it's doing. This removes
...
most of the "what the (*^&%(*^ was that?" stuff that normally flies by.

Pop the return address off the stack before making a V86_CALLF call;
...
this allows us to implement what look like C function calls from user
space "directly" to v86 mode code. (Used for calling the PnP BIOS)

Initial integration of the i386 bootloader and BTX.
...
- Discard large amounts of BIOS-related code in favour of the more compact
BTX vm86 interface.
- Build the loader module as ELF, although the resulting object is a.out,
make gensetdefs 32/64-bit sensitive and use a single copy of it.
- Throw away installboot, as it's no longer required.
- Use direct bcopy operations in the i386_copy module, as BTX
maps the first 16M of memory. Check operations against the
detected size of actual memory.

Resynch with working sources before BTX integration.

- Use format-independant module allocator.
- Conditionalise ISA PnP support.
- Simplify PnP enumerator interface.
- Improve module/object searching.
- Add missing depend/install targets in BTX makefiles.
- Pass the kernel environment and module data in extended bootinfo fields.
- Add a pointer to the end of the kernel + modules in bootinfo.
- Fix parsing of old-style kernel arguments.
