0aa3049bfc Performance tuning: change the default behavior of ompio to *not* segment individual read/write operations. 
In most cases, performance seems to be better if not segmented.

824d488709 - make the split collective shared file pointer operations work 
- minor code restructering in io/ompio required for that.

05c34946f7 implementation of non-blocking read/write operations through aio 
functions for the posix module. Som interface changes for the fbtl were
necessary for that.

dc05b709a7 it is ok to not have a sharedfp component selected, as long as no 
sharedfp functionality is being used. Return an error however if no
sharedfp component is selected and the applications calls a
file_read/write_shared function.

ed02927767 - do not set the contiguous memory option in the collective operations. It 
should not be stored on the file handle anyway, since it is not a property of
the file.
- protect a realloc for zero byte scenarios.

0f59ce6591 use the fbtl return value as originally intended, namely to retrieve the 
number of bytes written and read. Status contains now the actual number of
bytes written for individual operations. For collective operations, this is
unfortunately not possible.

  for explicit offsets

ac694b7056 in preparation for the new shared file pointer components to be committed 
soon:
 - add a new abstraction layer to be used internally for some operations
 - add a new mca parameter to control lazy intialization of shared file
 pointer structures

  yet implemented
