Descriptions:
When removing object header messages, it is possible for object header
continuation messages to move to a different chunk. When this happens, flush
dependencies need to be updated to reflect the new structure. This change adds
code to update the flush dependencies, and a test for this.
Also fixed a bug where the flush dependency no the object header proxy was not
being destroyed when an object header chunk was deleted.

Description:
Added flush dependencies between object header chunks. Also added a new object
header proxy object, which is a child dependency of all object header chunks.
All objects which are child dependencies of an object header should set up a
flush dependency on the object header proxy, so the dependency applies to all
object header chunks.

multiple parents
Description:
Reworked how flush dependencies worked internally, allowing multiple flush
dependency parents, and removing the notion of flush dependency heights, instead
keeping track of the number of dirty descendents to determine if parents can be
flushed. Also removed the requirement that cache clients destroy flush
dependencies before eviction (this is now handled by the cache) and removed the
maximum number of passes (the cache should detect infinite loops elsewhere).
Added test cases for this.

Description:
Since the "flush me last" code was introduced, it was no longer possible for the
superblock to be flushed to disk without flushing the entire file. This made it
impossible to open a file concurrently, even after calling H5Gflush on the root
group. The superblock was originally supposed to be flushed every time any
object was explicitly flushed with H5*flush.
Modified H5C_flush_cache to ignore flush me last flag if the entry is marked for
flush (which is done either by a tag for H5*flush or to free up space in cache)
and the flush marked entries flag is set.

Moved the file open/close back inside the loop in the SWMR reader
code. Without the open/close, the cache never refreshes so we
always see the initial amount.
Made a couple of other minor changes to the SWMR code.

- Added comments to files, functions, etc.
- Some readers changed to keep the file open throughout the
life of the program instead of closing it before sleeping.
This is in the hopes that there will be more opportunities for
cache issues without the close.
- Other minor changes.

Updates the SWMR testing
- All readers/writers now consume and emit their random seeds
for debugging.
- Output uses unbuffered I/O for more readable output.
- The random seeds are now based on a more fine-grained time
measurement to ensure each reader has a different random
seed.

Add flush dependencies to the fixed array code.
Description:
Added basic flush dependency wiring to the fixed array code. Does not
include the test code, which will be added soon.
NOTE: The Makefile.in change in test/ is not due to any changes made
here. It appears to be from a missing bin/reconfigure in a prior
checkin.

Description:
Adds SWMR support to the v2 b-trees when used as a chunk index. Because each
node keeps track of the total number of records reachable through each of its
children, nodes must be shadowed every time a descendent record is inserted or
removed. This implementation prevents this from happening, however, if the node
has already been shadowed since the last time the v2 b-tree header was flushed.
Also modified SWMR test to include v2 b-trees.
Tested: jam, koala, ostrich (h5committest), durandal
Note: There is a preexisting failure in the ph5diff (-v) test
