This adds compile-time logic to disable certain frontends in mini-os:
- pcifront is disabled by default, enabled for ioemu
- blkfront, netfront, fbfront, kbdfront, consfront are enabled by default
- xenbus is required for any frontend, and is enabled by default
If all frontends and xenbus are disabled, mini-os will run without
needing to communicate with xenstore, making it suitable to run the
xenstore daemon. The console frontend is not required for the initial
console, only consoles opened via openpt or ptmx.

Add two "special" PV consoles to stubdoms that are going to be used
to send and receive the qemu-xen save files on save/restore.
Use the second PV console to send the qemu-xen save file and the third
PV console to receive the qemu-xen save file on restore.
Fix the console shutdown function free_consfront that is called when the
qemu save file is closed.
Stubdom save/restore is still broken with xend.

The return value of Xenbus routines xenbus_transaction_start(),
xenbus_printf(), xenbus_transaction_end(), etc. is a pointer of error
message. This pointer should be passed to free() to release the
allocated memory when it is no longer needed.

In a lot of places in MiniOS frontends, xenbus_watch_path_token is
used instead of xenbus_watch_path to get more precise wake ups. To
free those, xenbus_unwatch_path_token has to be used instead of
xenbus_unwatch_path, else the unwatch operation will fail. This fixes
spurious watch events left by pv-grub.

MiniOS' console_print tries to expand '\n' into "\n\r" in place,
causing page faults if the string resides in text.
Use a duplicate of the string instead.

As part of making stubdom usable on NetBSD, it is necessary to
restructure the minios headers to avoid conflicts with NetBSD's
crossbuild toolchain.

evtchn_bind_interdomain used to clear any already pending event before
binding a handler, because else the handler may be called before it is
ready. That however leads to missed events, which I had to workaround
for the HVM case.
This changes the semantics of bind_evtchn, and thus of all the
event channel binding functions (bind_virq, evtchn_alloc_unbound,
evtchn_bind_interdomain) into not unmasking the event itself, hence
letting the caller initialize properly before unmasking the port (e.g.
record the port number in an appropriate place).
