afsio bypasses the cache manager to achieve higher throughput.
However, it uses the cache manager to stat or create files over the
AFS path.
Besides 'apropos' and 'help' there are 3 subcommands:
'write' pipes data into a new or empty AFS file
'append' pipes data at the end of an existing AFS file
'read' pipes data out of an AFS file
for 'write' there is an option '-md5' which calculates on the fly
the md5 chscksum and prints it to stdout. (Useful when you create
long time archives to keep it separately for later ...)
for 'write' there is also an option '-synthesize <size>' to do just
performance tests. It creates a file which contains at the
begin of each 4 KB block the offset printed in ascii.
for all subcommands exists a '-verbose' option which writes to
stderr data rate and timing information.
All three subcommands may also be used prefixed with 'fid' accepting
then a Fid instead of an AFS path. With the 'fid' prefix also a '-cell'
option is allowed.

The readpage call on Linux was becoming horribly complex.
This patch refactors it into three main components - a function which
fills a locked page (without unlocking it), a function which triggers
a cache bypass operation on a page, and a function which does
conditional prefetch, based on the properties of the page that was just
read.
In addition, we abstract out the cache bypass code further, and provide
static inline variants which are simply stubbed out when cache bypass is
disabled.

Introduce osi_compat.h, a place to hide compatibility #ifdefs. Make
a start on using this by purging #ifdefs from osi_vnodeops, and pushing
changes into inline compatibility functions.
The general idea here is to create a single location where we can do our
multiple version compatibility magic, and by doing so reduce the
complexity of the rest of the code. The approach is that where the
kernel introduces a new interface, we should switch to using it in the
rest of the code, and add a compatibility function (in osi_compat.h)
which implements the new interface in terms of the old one, suitably
protected by #ifdefs.
Where an interface changes signature, but not name, we should implement
an afs_<blah> version of the function which has the signature of the
newest version, and within that call out to the real kernel versions,
mapping between the different parameters as appropriate.

Make FSYNC_sync wait until VInit == 2 before serving FSSYNC requests.
This follows the existing similar behavior of waiting until after volume
preattachment is completed before serving RPC requests in DAFS. This
prevents FSSYNC clients from being denied requests simply due to a
volume not having been preattached yet, at the small cost of delaying
how soon we can serve FSSYNC requests.
This does not alter the behavior of non-DAFS, which still only waits
until VInit == 1, since volume attachment takes significantly longer
than preattachment.

This patch adds a '--enable-checking' configuration option. When this

creeping into the tree.
In order to still be able to build, all of the currently existing
warnings are accepted (these are documented in README.WARNINGS). With
this set of warning inhibitions, the tree is known to build on 32bit
Leopard - other systems may vary. Warning inhibition may be disabled
by supplying --enable-checking=all - in this case the tree will
definitely not build!
If --enabled-checking is not specified, the existing compilation
behaviour is maintained, so there is no user-visible change.
Gcc 4.2, or later, is required to use the pragma sets contained within
this patch. Again, they are not visible unless --enable-checking is
