Dmitry V. Levin a7c4ee41ff Mpersify parsers of struct stat and struct stat64
On many architectures that support multiple personalities,
struct stat differ between personalities.  While old code could handle
these differences, there are some architectures, e.g. sparc64, that also
have different struct stat64.  Rewrite parsers using mpers functionality
to fix these issues.

* fetch_struct_stat.c: New file.
* fetch_struct_stat64.c: Likewise.
* print_struct_stat.c: Likewise.
* oldstat.c: Likewise.
* stat.c: Likewise.
* stat.h: Likewise.
* stat64.c: Likewise.
* file.c: Remove.
* printstat.h: Likewise.
* linux/aarch64/stat32.h: Likewise.
* linux/powerpc64/stat32.h: Likewise.
* linux/riscv/stat32.h: Likewise.
* linux/sparc64/stat32.h: Likewise.
* linux/tile/stat32.h: Likewise.
* linux/x32/stat32.h: Likewise.
* linux/x86_64/stat32.h: Likewise.
* Makefile.am (strace_SOURCES): Add fetch_struct_stat.c,
fetch_struct_stat64.c, print_struct_stat.c, oldstat.c, stat.c, stat.h,
and stat64.c.  Remove file.c, printstat.h, linux/aarch64/stat32.h,
linux/powerpc64/stat32.h, linux/riscv/stat32.h, linux/sparc64/stat32.h,
linux/tile/stat32.h, linux/x32/stat32.h, and linux/x86_64/stat32.h.
* configure.ac (AC_CHECK_MEMBERS): Add struct stat64.st_mtime_nsec.
* defs.h (struct strace_stat): New declaration.
(print_struct_stat): New prototype.
* linux/dummy.h (sys_fstatat64): Remove.
