fix id_gen_safe static allocation leakages. Note that the job interface (to return op ids through the system interface) is really the only user of the id_gen_safe code. The bmi layers call it as well, but only from _test and _testsome, which aren't ever used at presnet in PVFS.

Also increase the number of buckets in the id_gen_safe hashable. 67 gives a loading factor of about 50...we're probably going to want to allow more operations in-progress than that in todays world.

- added a license notice for the GPL'd kernel module code in COPYING
and README files
- added Murali to the CREDITS file
- added a configure check for the kernel 2.4.x minor version to know
if we need to define a few functions or not
- added a new pvfs2-error-code that can be used as an exit code for
the pvfs2-client-core to indicate to the pvfs2-client that it should
continue respawning it, but to sleep for a bit first. [2.4.x in
particular waits a while to release the device file after the
process has died, though the same is possible under 2.6.x i guess]
- updated the test mount script with 2.4.x support if running 2.4.x
- added some debugging to client-side create state machine
- murali: fixed a logic bug in mmap-ra-cache
- murali: added matching unlocks to quickhash code functions
- removed MOD_{INC|DEC}_USE_COUNT calls, as at least under my 2.4.26
testing, they are not necessary
- removed several lock_kernel calls in the 2.4.x code paths that
caused the kernel to hang in a few places (still investigating)
- murali: fixed the in kernel mount option string parsing
- some misc cleanups
- verified that symlinks now work (at least in basic testing)

[ NOTE: this mostly works under 2.4.26 in my testing, however there
are some known problems remaining ]

This is a full merge of my pvfs2-dbpf-attr-cache-branch, so this is
the cumulative changelog (based on existing cvs messages).

- initial dbpf-attr-cache implementation and cleanups
- added all the hooks to grab configurable cacheable metadata keys
from a config file. re-arranged the config file by separating out
fs specific hints into a StorageHints area. updated genconfig to
account for these changes.
- initial working implementation of the unified dbpf-attr and
keyval/data pair cache. holy cow this thing is fast... much work to
be done still.
- initial locking added
- replaced debug level with a new DBPF_ATTRCACHE_DEBUG level
- added safe to/from cache data copies
- added write-through caching for keyval data (still need to do generic attrs)
- updated simple.conf
- allow config file to have multiple AttrCacheKeywords lines
- fix some cache parts that allow symlinks to work (i.e. be cached)
- added a verbose warning for a particular kind of configuration error
for a user to see if it should happen
- some more robust configure checks
- more configure related changes
disable vis build if sdl is detected, but sdl-ttf isn't
- fix broken ifdef nesting that caused compilation failure on non
aio-threaded configurations
- safe copy of attributes (to/from, preparing for write-through impl)
- server cleanups (making way for pre-caching of a number of attrs on server
startup since it reads them from disk during handle iterate anyway)
- update create test program to report human readable creation error
- put some quick human readable error reporting in pvfs2-client-core
- added some quickhash method we've been wanting but never had
- implemented policy to limit previously unbounded size of attr cache
- adjusted simple.conf to have some good defaults
- adjusted pvfs2-genconfig to match those defaults
- fixed some htable cleanups
- started write-through attr updates
- update changelog and version info, preparing for mainline merge
- implement write-through of dbpf-resize operation
- make sys-truncate return -PVFS_EINVAL if truncate is called on an object
that can't be truncated
- fix error code return value of sys-truncate
- cosmetic changes to truncate test program output
- added some comments
- updated showconfig with copyright info
- updated sample configs for showconfig
- added a default handle purgatory value if a value of zero is specified
(e.g. not specified in config file at all)
- for now, remove the cached dbpf-attr object on i/o writes
- slightly robustify the glibc aio callback detection

some vfs related cleanups; a quickhash bug fix for kernel compiles;
a naive pinode/pcache reclamation method (that's off by default) to
help try to bound the number of active pinodes at all times.

but since we're breaking everything anyway, here goes.

Modified quickhash to prepare sharing the implementation with userspace and
kernel land. In kernel land, spin locks are used. Also added a new function
that both finds an element and removes it atomically.
