In the case where the preferred kernel locations are not available,
make load_linux() smart enough to be able to relocate the kernel if at
all possible.

Impact: should deal with memory holes more gracefully

Right now, if we find a memory hole, we simply don't use the memory
beyond that point.  This makes it possible for com32 modules to
use that memory.  After this, we should be able to add relocation
support to allow loading when the memory at 1 MB is unavailable.

No more direct __intcall()'s in this code, so remove unused register
set variables.

Copy the disabled fixes already done in ansicon from checkin
22cd4e378e3aafd402f43030941d6f6b300d0cea.

Even when disabled, we need to set the screen size, because the
downstream code depends on it.  Set it to 25x80 (maybe we should
swtich this is 24x80) in this case.

Furthermore, when disabled, we should return success == bytes
"written", not zero.

Regarding the vesa spec, total_memory is reported to be 16bits
That 32bits field had shifted the whole structure and prevented
reading other fields properly.

Make _Exit just an ordinary symbol which aliases _exit.  This avoids
some versions of gcc complaining about the inline, which is rather
unnecessary anyway.

Older versions of gcc/binutils apparently really want parentheses
around macro arguments.
