VFS: implement sendfile file operation
Currently the sendfile syscalls hardcode assumptions about the
implementation of the read file operations implementation. Although
it checks for the presence of a readpage address-space operation
filesystems in Linux are free to implement read differently from
the generic version (generic_file_read). Many filesystems such
as tmpfs, smbfs or xfs chose to implement it differently and need
additional locking, revalidation or checks.
