afsio is a utility for file transfer to and from AFS file space
without the help of the AFS client/cache manager. Using libafscp,
this (partially rewritten) version of afsio is able to accomplish
(1) authenticated access to an AFS path or FID (an existing
KerberosV ticket is required), (2) fall back on unauthenticated
("anonymous") access if authentication (token acquisition) fails,
and (3) work independtly of the AFS cache manager (afsd need not
be running, though CellServDB and ThisCell are currently required).
issues:
1) libvldbint and libafsint are not compiled pthreaded. we link in
what we need. this should be changed when we are all-pthreaded.
2) venus is not a pthreaded-directory otherwise. same deal:
in an all-pthreaded universe, undo the bodge that we do here.
3) venus is not an all-krb5 directory either. slight ick.

When detecting if we have certain Linux kernel features, we only

compilation fails if we include dcache.h directly (due to e.g.
list_head not being defined), which causes false negatives in tests
such as the test for dcache_lock. If we instead include fs.h, which
includes dcache.h, the tests succeed when they should succeed. So, use
fs.h instead of dcache.h.

Some versions of HP-UX have the pread() and pwrite() functions, but
they behave in odd ways; most notably, ignoring the offset argument
when _FILE_OFFSET_BITS is defined to 64.
This is noted in recent gnulib documentation
<http://git.savannah.gnu.org/cgit/gnulib.git/tree/doc/posix-functions/pwrite.texi>,
and slightly less clear references to pread() being broken can be
found on the development mailing list for git itself.
It is not completely clear what specific HP-UX versions are affected
by this. An autoconf run-time test may also be insufficient, because
the same binaries should be usable on machines with broken and
non-broken pread() implementations. So, to be safe, disable positional
I/O on HP-UX unconditionally.

Previously, building with Kerberos support required either passing a
flag to configure giving the location of a krb5-config script, or
manually setting variables specifying the Kerberos libraries and
header path. Replace that code with code that checks for Kerberos
libraries automatically and builds the Kerberos code if any were
found, with support for doing direct library probing if there is no
krb5-config script.
Add several platform-specific overrides directly into the configure
support, so we should be able to build out of the box on Mac OS X 10.3,

The Kerberos Autoconf macros are now the versions that come with

OpenAFS and those packages will be able to benefit from further

Add a configure test and cope.

If we are building for are kernel with keyrings, and we can
guarantee that we can make use of those keyrings, then we no longer
need to probe for the syscall table at all. Change our default
behaviour so that when these two conditions are true, syscall probing
is disabled. Both --enable-linux-syscall-probing and
--disable-linux-syscall-probing can be used to override the
autodetection and force things one way or the other.
We have to check that we can use the keyrings because there was a
window in the 2.6 kernel series where keryings were available, but
the key_type_keyring definiton (which we use to create the session
keyring) wasn't exported. In that situation, we attempt to traverse
the process table and use the type of init's session keyring. This
traversal is fragile, and if it fails, keyring PAGs will be disabled.
So, we still want to be able to fall back to patching the syscall
table, if we can, in this case.

Use AC_TYPE_SSIZE_T to handle the ssize_t check (introduced in Autconf
2.60). Use AC_CHECK_TYPE, not AC_CHECK_TYPES, to check for sig_atomic_t
and socklen_t, and define them in afsconfig.h if they're not present on
this platform. Do not define them in stds.h, since stds.h is an installed
header file and cannot rely on Autoconf defines.

The Linux read/write file operations take a position. Use this
position to determine where we're reading or writing in a file,
rather than using the vfs_llseek() operator to set the file
position argument. This avoids a potential race condition, as
well as simplifying this code.

Define the PageCheck family of functions using PageFsMisc
equivalents if those are found. I encountered a need for this
on Centos 5.5 (2.6.18-8.el5xen), but it may be more general.
