When the memory overhead for memory usage tracing is bigger than
the threshold value, a warning message is generated to indicate the
amount of the memory used in the tracing. Environment variables
to control the threshold value were added.

We were creating duplicating information in the operation structure
and in the packet structure when the message is actually issued.
Since most of the information is the same anyway, this patch just
embeds a packet structure into the operation structure.

Reopens #1788  (datatype performance tests failing)

but better to have poor performance than incorrect performance

Closes #2115 (RMA fails with derived type containing struct of struct)
Closes #2126 (Data Integrity issue in MPI_Gather ...)

Conflicts:
	src/mpid/common/datatype/dataloop/dataloop_optimize.c

but only because a subsequent commit removed bits of this optimization.
This commit fully removes this optimization, but we leave behind test
cases to help us make sure we get it right next time.  We also leave
behind some additional debugging support routines.

https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/405

 says :
"The use of the datatype MPI_CHAR in the MPI tool information interface implies a
null-terminated character array, i.e. a string in the C language. If a variable has
type MPI_CHAR, the value of the count parameter returned by MPI_T_CVAR_HANDLE_ALLOC
and MPI_T_PVAR_HANDLE_ALLOC will include the null-terminating character."

Unlike cvars of type MPI_INT etc, MPI_CHAR cvars need explicit memory allocation for their storage.
Note: In MPI standard, MPI_CHAR is not in types of pvar.

The old value (4096) was arbitrarily chosen. To save memory and to make cvar
tests cover the MPI_CHAR case easily, we set it to a smaller value, which is
still big enough to hold reasonable cvar strings.

On FreeBSD and Darwin, the read and write system calls think 2147483648 (2^31:
larger than a signed 32 bit integer can hold) is an invalid amount of data.
Maybe, despite taking a size_t parameter, something internally treats the count
as an int.  Fine, we'll take measures to never write more than 2^31-1 bytes.

Testcase for "RMA fails with derived type containing struct of struct"

See #2115

declare "handle_error" with a const string to make compiler happy

this optimization in ROMIO's noncontigous type handling detects if a
user-defined type will fit into a single write request (e.g. a call to
MPI_Type_create_subarray that was actually the entire array).  Code was
passing in a count of bytes, which can overflow an int. since we know
the type is contiguous, simply pass a count of that type (not bytes) to
write_contig

The f2c/c2f handle conversion functions are only defined in C in the standard.
We provide non-standard extensions in Fortran. All functions, except MPI_File_f2c/c2f,
are trival to implement. For MPI_File_f2c/c2f, we bind the Fortran functions to C.
We do not provide PMPI version for them since it is not required by the standard.

No review since F08 binding is experimental now.
