501b1d7983 Avoid extra allocation in parity file 
After growing the parity file, call an extra ftruncate()
to ensure to cut the file to the exact size, removing any extra
allocation that could result by failed attempts to grow it.
Note that how fallocate() behaves on failures is not really
specified, so it's possible that extra space is allocated.

18cc80bd7e Now pread and pwrite use is required for multithread 
We need to support concurrent access at the same file handle
from multiple threads, and they cannot share the same file pointer.

cbf2040b89 Add mutex protection at the filesystem structure 
In sync we need to modify the filesystem, like to call
fs_deallocate(). We need then proper protection.
This also removes the need of multiple fs_last cached value.

9bc5f9e5ce Change the internal mapping to a tree of chunk 
This is intended to save memory as now we can use a fixed
block of 17 bytes to store the block information, compared
to the previous 28/36 bytes.
