Fix bug in BMI reference counting. Previously the server was responsible
for both incrementing and decrementing count while working on a state
machine, but this leaves a window of time between completion of
testunexpected() and the start of a state machine. If a connection was
reset during this window it could cause state machine to try to use
non-existent BMI address, with some odd results.

This patch adds a flag that the server can use to have BMI automatically
increment reference count on any unexpected message before it is passed to
the server for processing.

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.

[phil]: alternative lio_listio implementation that spawns a thread and does pwrite/pread.

[phil]: bmi-socket-close: This fixes a bug in the new BMI_set_info(... BMI_TCP_CLOSE_SOCKET ...) mechanism, which is used to reconnect the socket to the initial configuration server if new socket buffer sizes are specified in the config file. I didn't follow the code path find the exact problem, but at a high level it wasn't being thorough enough in cleaning out the old socket. This showed up when using epoll and specifying socket buffer sizes in the server configuration- in this case the client will often fail to mount with a cryptic "not a directory" error and leave some epoll() errors in the pvfs2-client.log file. I think a stale (or possibly reused) file descriptor was being left in the epoll fd set. At any rate, the fix is to use a different set of functions for tearing down the entire address etc. so that it is reconnected on the next BMI addr lookup. This path is already used by the server to discard old BMI addresses after critical errors on addresses that cannot be reconnected. It is triggered from bmi.c without entering the bmi_tcp module, so this patch also adds a check to make sure we don't bother for non-tcp methods.

[phil]: bmi-test-overflow: One of the bmi bandwidth test programs was using types that might overflow if testing large enough transfers. The fix is to convert to doubles and drop in several type casts to be cautious when performing the computation that was causing trouble.

[phil]: cancel-bugs: The biggest fix here is a change to the job timer code. It was performing some pointer operations in the wrong order, which could lead to job timers failing to trigger in some cases. This would prevent some operations from ever timing out. A secondary fix is a minor cleanup in BMI to catch potential race conditions in cancellation where a lock wasn't being held while checking to see if the target operation is complete.

[phil]: flow-post-error: This patch adds checks in the client side I/O state machine to test for failure at post time for flow operations. This type of error is uncommon unless the flow parameters are faulty, but it should have checked anyway to be safe.

[phil]: dfile-config-check: This is a safety test. The problem here is that there was no bounds checking for the DefaultNumDFiles option in the config file. This made it possible to select -1 (which in PVFS1 meant "use the default number"). In PVFS2 this number gets passed verbatim to the client and would cause malloc failures and various other odd results when used. The patch just checks at parse time to make sure the value isn't negative.

[phil]: bmi-flow-logging: This patch just adds a little bit more gossip logging output to BMI and the flow protocol. In particular, it adds tag information to messages about BMI operations, and adds pointer information to the flow protocol to help match posts and completions of flows in log files.

[phil]: server-freopen: This patch just removes duplicate calls to fdreopen(stdin/stdout/stderr) that were being performed on server startup when the server is run in the background. The first set should be sufficient.

Fixes for the latencies noticed in BMI (by Julian) when the main thread is waiting in the poll/epoll_wait
and another thread indicates that data is ready on another socket which is not being watched.
In the poll case, the fix (suggested by pete) is to create a pipe and add the pipe fd
to the poll set being watched. Adding a socket for watch also sends a 1 byte message over the pipe.
This in turn caused the poll() thread to break out of the poll and cause it to retry with the updated poll
sock set.
For the epoll case it is perfectly safe for the thread adding the socket to the watch list to call
epoll_ctl() directly since the kernel takes care of necessary serialization for that.

merging small I/O changes to trunk. The majority of this commit includes the
new small I/O state machines on client and server, and the modifications to
the client IO state machine. It also includes mods to the zero-fill code
to perform zero-fill of holes only if they exist instead of zero-ing the entire
memory region initially. Also, some debug stuff has been added to the
state machine processing code to print enter/exit of state machines if sm
debug is enabled. The genconfig now includes ioports/metaports for running
multiple servers on the same host for testing.

Attached patches implements trusted ports and networks similar to
what PVFS1 implemented.
It adds a new <Security> </Security> tag to the fs.conf config file
and parse utilities accordingly. We can edit these later if there
is a strong need.

Within these tags, you have to specify TrustedPorts <Range of ports> and
TrustedNetwork tcp://<network> tcp://<mask>.
I dont know how to support this cleanly on non tcp/ip bmi
architectures, so currently this only enables it for the bmi_tcp module
alone. (i guess we could do it for bmi_ib module as well but not done
until someone says that is the right thing to do...)

Also adds support for a --trusted argument to the pvfs2-genconfig script
that will prompt for the trusted port ranges and the network address/masks and write it out
to the fs.conf and server.conf file.

Configure now supports a --enable-trusted to enable all these features.
(NOTE that the fs.conf tags (or lack of one) still allow you to not
select these features even if configure was asked to compile with this
option).

this patch also cleans up all the warnings that arises with gcc
(3.4) and --enable-strict build mode.

step one of some lock reorganization- get rid of "one big mutex" that
serializes all BMI calls, and put burden of thread safety on individual
modules. for now this means that each module has its own big mutex to
serialize things, but this can be optimized on a per module basis later.

this is a necessary step towards making pvfs2 work under nptl; the fact that
we hold mutex locks for too long seems to exacerbate starvation problems
in that environment...

Change BMI send functions to accept const buffer pointers.
   Change BMI list functions to promise not to modify the lists themselves.
   Some casts in BMI methods are to stick non-const pointers in const pointer
   storage to permit the use of generic functions for both send and recv.

big changes to various I/O API's- there are no longer any "wait"
functions in the BMI, flow, or request scheduling APIs. In the
request scheduler case, they have simply been discarded. In BMI
and flows, the testXXX() functions have been augmented with a
timeout argument so that they may perform the role of the
former waitXXX() functions.
