Bug Fix:flush not yet saved data before a read outside buffer

Random Read and Write with holes test programs+ Fix Read/write
file closing: takes into account the pending r/w req. before releasing

Because of the readahead it might be possible that there is some
read pendings. Incase of file cloe, Rozofs needs to wait for the
response otherwise the file descriptor might freed.
The case of the write was already addressed. Here we have a
protection against a potential write after close (not
really possible, but we need to protect Rozofs from that situation

Enhancement: when a read response is received, only the unread
part is filled in the fd's buffer. Rozofs provides fuse we
the pointer to requested section avoiding unnecessary data copy.
Address the case of the empty blocks in the Read/write:
When a block is empty avoid calling the transform.
Computed received length after truncate may be negative
