Restores CONFIG_ACPI_HT_ONLY as an alternative to CONFIG_ACPI
rather than a prerequisite

Monotonic clock code uses reader/writer lock which is prone to same
starvation problems as we saw with xtime.  This patch changes it to seq_lock
which is faster and won't starve writers in face of lots of readers.

Introduce a new kernel-userspace interface that uses 128-bit file
identifiers instead of the previously used 96-bit fileids. We also
replacing the coda_creds structure with only the fsuid.

This new API has been used by for a couple of months now, people had to
patch their kernels whenever they want to run a current Coda release.
A new Kconfig option is added to fall back on the old API for older Coda
clients and other userspace filesystems that might use our protocol.

The ViceFid structure is really a Coda server datatype and the kernel
really shouldn't have to know its internal structure. Replace all
instances with struct CodaFid with opaque members.

Both userspace and the kernel are testing only the fsuid part of the 
coda_creds credentials structure. Nothing else is really used, so we now
match the code with the actual usage by only passing fsuid around. The
kernel-userspace API is kept compatible (for now).

Use a global 'epoch' counter to invalidate cached permissions instead of
traversing a racy linked list of all known Coda inodes.

  - Remove unused functions and variables.
  - Be a bit more strict with the definition of various types that are
    shared between kernel and userspace.
  - Included a couple of cleanups from Maximilian Attems and Stephen
    Hemminger.

A recent change causes pervasive data corruption by over-writing inode
metadata with a word of garbage.  The field, di_rdev, should only be set
for a device inode.

Note that this restores CONFIG_ACPI_HT_ONLY as a sub-set of CONFIG_ACPI rather than a dependency.

This will allow fixing races with rmmod and sysfs access.
