finish up incomplete job of moving structure used by bioscall() to
<machine/bioscall.h>, with associated changes in include file strategy,
genassym stuff, etc.
/*
* void bioscall(int function, struct apmregs *regs):
* call the BIOS interrupt "function" from real mode with
* registers as specified in "regs"
* (for the flags, though, only these flags are passed to the BIOS;
* the remainder come from the flags register at the time of the call:
* (PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
*
* Fills in *regs with registers as returned by BIOS.
*/
Thanks to Charles Hannum for complaining and inspiring me to hack this
together.
