3dd49be938 Allow human readable name for the root device.
Instead of using rootdev= or ramimagedev= in the boot monitor
which are changed to numbers and cannot be used with other
loaders, rootdevname= or ramimagename= are (MINIX-style)
device names always stored as strings.

8979450631 Rotate kernels/images/modules.
Kernels and system services are stored in a single directory in the
/boot/minix/ and rotated like /boot/images. /boot/minix_latest slink
is created automatically.
System serives are prefixed by "modNN_" to allow to easily load them
using "mod*" pattern.

7f2d47d84c Remove libkern, leave just header.
Boot stuff dependencies from NetBSD.

Patch by Antoine Leca. Relocated to src/sys.

The port is using the same libminc.a as usual MINIX services (and does
not use NetBSD libkern); the headers imported from NetBSD sys/ tree
have been kept to a minimum (still numbers higher than 30 though.)

Note the peculiar way to use libraries (libsa, libi386, etc.): the
source code is shared, but each component builds its own copy of the
library, with its own set of preprocessor defines.

Also following functionality was added:
- Add install_master to the installboot from NetBSD.

abd6043a2f AVFS: fix various system call interruption issues
- When cancelling ioctls, VFS did not remember which file descriptor
   to cancel and sent bogus to the driver.
 - Select state was not cleaned up when select()ing process was
   interrupted.
 - Process trying to do a system call at the exact same time as a user
   trying to interrupt the process, could cause the system call worker
   thread to overwrite state belonging to the worker thread trying to
   exit the process. This led to hanging threads and eventual system hang
   when this happens often enough.

4d3a0887b4 AVFS: only put mount point when it was used as one
When a mount operation fails and the FS exits, free_proc could try and
clean up resources associated with the mount point before the mount
thread itself can do that. However, the clean up procedure should only
clean up resources that were actually in use.

0bd011affd PM: extend srv_fork to set a specific UID
Currently, all servers and drivers run as root as they are forks of
RS. srv_fork now tells PM with which credentials to run the resulting
fork. Subsequently, PM lets VFS now as well.

This patch also fixes the following bugs:
 - RS doesn't initialize the setugid variable during exec, causing the
   servers and drivers to run setuid rendering the srv_fork extension
   useless.
 - PM erroneously tells VFS to run processes setuid. This doesn't
   actually lead to setuid processes as VFS sets {r,e}uid and {r,e}gid
   properly before checking PM's approval.

5c0927e108 SMP - clock calibration spurious IRQ deadlock fix
- this patch fixes a deadlock which may occur if we get a
   spurious interrupt while calibrating clocks during the boot
   time. Since we never handle interrupts while in the kernel
   (BKL locked) the interrupt code locks the lock. This is a
   different situation, a corner case, boot time only. We do not
   return to userspace but to the kernel, so the BKL is not
   unlocked. So we need irq handler which leaves the BKL
   unlocked.  The clock handler does it already, this patch adds
   a dummy spurious irq handler for the same reason. It is better
   to handle the situation this way to keep the normal runtime
   code simple.

c468f4efa5 SMP - no_apic=0 and acpi=1 set when CONFIG_SMP=y
- this is a temporary change which makes images compiled for SMP
  boot in SMP mode by default.

- this change is needed until we can configure the multiboot
  images from the boot loader again.

ddbdca6cdb Add support for survival of crashed FSs
When an FS crashes, VFS will clean up resources tied to that FS:
 - Pending requests to the FS are canceled (i.e., fail with EIO)
 - Threads waiting for a reply are stopped (i.e., fail with EIO)
 - Open files are marked invalid. Future operations on a file descriptor
   will cause EBADF errors.
 - vmnt entry is cleared, so in-flight system calls that got past the
   file descriptor check but not yet talking to the crashed FS, will
   fail with EIO.
 - The reference counter of the mount point is decreased, effectively
   removing the crashed FS from the file system tree. Descendants of
   this part of the tree are unreachable by means of a path, but can
   still be unmounted by feeding the block special file to unmount(2).

This patch also gets rid of the "not a known driver endpoint" messages
during shutdown.
