Fix decoding of statfs family syscalls

Fix decoders of fstatfs, fstatfs64, statfs, and statfs64 syscalls
by rewriting them using mpers infrastructure.

Add checks for f_frsize and f_flags members of these structures.
* defs.h (struct strace_statfs): New forward declaration.
(print_struct_statfs, print_struct_statfs64): New prototypes.
* Makefile.am (libstrace_a_SOURCES): Add fstatfs.c, fstatfs64.c,
statfs.c, and statfs64.c.

and statfs.h.
* NEWS: Mention this fix.

This is strace -- a diagnostic, debugging and instructional userspace utility for Linux. It is used to monitor interactions between processes and the Linux kernel, which include system calls, signal deliveries, and changes of process state. The operation of strace is made possible by the kernel feature known as ptrace.

strace is released under a Berkeley-style license at the request of Paul Kranenburg; see the file COPYING for details.

See the file NEWS for information on what has changed in recent versions.

Please send bug reports and enhancements to the strace mailing list.
