… fixed an issue for initialization of map of files to handle in memory
This commit fixes the read operation when file is stored in memory. TODO: fix as soon as possible the ReadRequestCacheMEM class, as right now it might contain bugs somewhere that are not clear. Also some varibles can be removed
Caches now work independently of size. Increased posix read cache line size to 32K of data
Since caches are used to improve performance for small size IO operation, when a read() operation that targets a size greater than the size of the read cache line size is issued, the cache is being bypassed and the read operation occurs directly from the shared memory segment.

- Fixed mechanism to send memory storage regex - Added flag to store everything in memory - Added request for memory file in init_client() - Fixed an issue in return value for posix in memory write handler, and fixed an issue for initialization of map of files to handle in memory - Fixed write in memory for simple test - Fix on writev - Fix on cache wrong bytes. TODO: fix wrong read size - Completed IO operations on single machine - Added test for read and write in memory file. broken when reaching 1.3MB of data - Bugfix on offset calculation in capio memory file - Fixed reads on different mem pages - Fixed custom cache line size issues - Caches now work independently of size. Increased posix read cache line size to 32K of data - Improved test with bandwidth data - Performance improvement for data transfer: Since caches are used to improve performance for small size IO operation, when a read() operation that targets a size greater than the size of the read cache line size is issued, the cache is being bypassed and the read operation occurs directly from the shared memory segment.

This merge brings back the option to store the files inodes inside the CAPIO main memory. The mechanism can be used in two different ways:
This commit also adds tests to check capio server storage service, as well as bandwidth in both read and write.
