merge with Orange-Branch

Change PINT_dist_finalize() to unregister and free distributions cleanly. Adding unregister() call to distributions for clarity

Reverse merged and ported to HEAD.

reverse merge of trunk changes since branch.

reverse merge latest trunk changes to small-file-branch and update msgpair
usage where needed

Merge from HEAD

Fix small memory corruption if user specifies a particular distribution in
server.conf.  Distribution registration may round up the name_size to something larger than the length of the string allocated by dotconf.

Update migration branch to current CVS version

reverse merge of HEAD to WALT3 branch.

backmerging of HEAD to branch...

discard walt's bad cheese

revert style changes back to previous versions.

run maint/pvfs2indent-80col.sh on all .c files to correct style :)

fix warnings on 64bit.

change distribution storage encode/decode to use wire encoding.

distribution decoding without 64bit warnings.  one. last. time.

fix 64bit warnings

commit of murali's 64bit fixes.

replaced zero-fill code in client io state machine with one that works.  We:

* zero the buffer according to the memory request
* do flow
* calculate return size:
 - check that the ub of the file request is within file data (not a hole or past eof) -> return_size = sizeof(filereq)
 - if that fails, search through retreived datafiles for offset > ub_file_req -> return_size = sizeof(filereq)
 - if that fails, get all the datafiles and search through them for offset > ub_file_req -> return_size = sizeof(filereq)
 - if that fails, calculate correct return size from file req and eof
  * while(next_contig_segment(file_req).ub < eof)
      return_size += sizeof(current_contig_segment(file_req))
    if(current_contig_segment(file_req).lb < eof)
      return_size += (eof - current_contig_segment(file_req).lb)

---

* Added a test for holes and appropriate zero-fill behavior
* Also fixed error reporting for ping to display individual server errors.
* Fixed a bug in PINT_dist_copy

- applied Nathan's expandtab patch (expandtab-2.patch.gz)

Changing distributions to require initialization before use.  Giving
distributions an additional hook/callback to be called once at registration
time for the distribution to allow it to register its parameters and set
parameter defaults as neccesary.

Distribution cleanup and refactoring.  All naming is consistent with PVFS2
naming schemes.  Added new methods PINT_dist_methods to enable distribution
to determine the number of datafiles to use.  Removed unused methods (encode
and decode) from distributions (encode_lebf and decode_lebf are the preferred
mechanism).

Update naming conventions to match current standards.

Rename PVFS_Dist to PINT_dist
PVFS_Dist_create => PVFS_dist_create
PVFS_Dist_free => PVFS_dist_free

Clean up more naming, and restore basic distribution as the "default" (tho
simple stripe is, as always, the de facto default.

Cleaning up distribution framework.

Regularizing distribution naming for simple_stripe and modifying params to be
include friendly.  Simple stripe distribution has been moved to files
include/pvfs2-dist-simple-stripe.h and io/description/dist-simple-stripe.c

Existing simple-stripe.[h|c] still exist but are deprecated.

- rename all gossip masks to GOSSIP_xxx
- some misc cleanups

interesting 64-bit related changes

distribution changes:
always lookup methods
fix copy routine to point pointers into newly allocated dist
add consts in some prototypes
rearrange PINT vs PVFS headers to expose encode methods and simplify
add Dist encoding rules
change PACK_SIZE to round up to avoid unaligned params accesses
add encoding funcs to simple_strip and default_dist

added free, copy, and param funcs for distributions

added a DIST_DEBUG flag for gossip; gossipified some fprintfs in dist
code; added a line in the server to log what it's logging.

fixed a little pointer warning
added logical_file_size method to distributions

working on EOF issues in request processor

fixed a bug in the distribution encoding function

fixed some warnings - changed order of args for request commit

brought Walt's io description code over from the old pvfs2 tree
