move cominit() prototype to comvar.h, so that ports which use 'com' for serial console, but don't use the (i386-specific) comcninit()/comcnprobe() functions, can do the right thing.

convert these to use new <machine/bus.h> interfaces. This involved substantial reworking of the multi-port drivers, as they need to frob bits in the io-port spaces of their children. As a result, the commulti->com attachment interface is substantially more complex. (This may be fixable in the future by making some of the code common, but as long as io-port allocation checking is planned, it's necessary.)

New bus.h implementation/interface: - No more distinction between i/o-mapped and memory-mapped devices. It's all "bus space" now, and space tags differentiate the space with finer grain than the bus chipset tag. - Add memory barrier methods. - Implement space alloc/free methods. - Implement region read/write methods (like memcpy to/from bus space). This interface provides a better abstraction for dealing with machine-independent chipset drivers.

define and export the global variable "comconscflag", the default tty 'cflag' for the console. Normally set to TTYDEF_CFLAG, may be overridden by machine-dependent console attachment code, as necessary. (Alpha uses it to set cs8 -parenb.) Files including comvar.h now need to include <sys/termios.h>, because comconscflag is of type tcflag_t.
