7511a5540e Remove BIOSSEG.
Don't mess with the flags when entering a software interrupt.
Use IF, not VIF.
NOTE: These changes break dosemu, but are required for proper emulation.

c8ab43244b Actually keep track of the naughty PSL bits.
Use VIF, rather than IF, by default, to be compatible with dosemu.  XXXX

48643c6605 Export [gs]et_vflags(), and always use them when saving/restoring registers
in VM86 mode.
Allow changing of *all* PSL bits in VM86 mode; some applications don't work
right otherwise, and all the nasty bits are virtualized anyway.
Make sure PSL_VIF, PSL_VIP, and PSL_VM don't show up in the user's view of
the PSL.
