Bruce Evans 1fe048505d Replaced I586_OPTIMIZED_BCOPY and I586_OPTIMIZED_BZERO with boot-time
negative-logic flags (flags 0x01 and 0x02 for npx0, defaulting to unset = on).
This changes the default from off to on.  The options have been in current
for several months with no problems reported.

Added a boot-time negative-logic flag for the old I5886_FAST_BCOPY option
which went away too soon (flag 0x04 for npx0, defaulting to unset = on).

Added a boot-time way to set the memory size (iosiz in config, iosize in
userconfig for npx0).

LINT:
Removed old options.  Documented npx0's flags and iosiz.

options.i386:
Removed old options.

identcpu.c:
Don't set the function pointers here.  Setting them has to be delayed
until after userconfig has had a chance to disable them and until after
a good npx0 has been detected.

machdep.c:
Use npx0's iosize instead of MAXMEM if it is nonzero.

support.s:
Added vectors and glue code for copyin() and copyout().
Fixed ifdefs for i586_bzero().
Added ifdefs for i586_bcopy().

npx.c:
Set the function pointers here.
Clear hw_float when an npx exists but is too broken to use.
Restored style from a year or three ago in npxattach().
