Do not truncate return value of get{,e}[ug]id and setfs[ug]id syscalls
This should not be a user visible change unless the kernel does
something completely unexpected. In the latter case, let user see
what is going on.
* uid.c (SYS_FUNC(getuid), SYS_FUNC(setfsuid)): Do not truncate
tcp->u_rval to uid_t on exiting syscall, return RVAL_DECODED.

Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't. This
change fixes the inconsistency by adding missing copyright headers.
It doesn't mean that copyright headers became maintained. In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.

Fix decoding of getgroups, getgroups32, setgroups, and setgroups32 syscalls
Convert parsers of these syscalls to the same scheme as were applied to
parsers of other uid/gid related syscalls.
That is, define two sets of parsers on architectures that support
(either directly or via multiarch) 16-bit and 32-bit gid getgroups
and setgroups syscalls simultaneously, and reuse essentially the same
code by parametrizing uid_t and names of parser functions.
* groups.c: Remove.
(sys_getgroups, sys_setgroups): Move ...
* uid.c: ... here and parametrize their names.
* Makefile.am (strace_SOURCES): Remove groups.c.

Fix decoding of 16-bit *chown and [gs]et*[gu]id syscalls
Define two sets of parsers on architectures that support (either
directly or via multiarch) 16-bit and 32-bit uid/gid syscalls
simultaneously. Since the code in these two sets is essentially
the same and the key difference between them is the size of uid_t,
implement it by parametrizing uid_t and names of parser functions.
* defs.h (NEED_UID16_PARSERS): New macro.
* linux/syscall.h [NEED_UID16_PARSERS] (sys_chown16, sys_fchown16,
sys_getresuid16, sys_getuid16, sys_setfsuid16, sys_setresuid16,
sys_setreuid16, sys_setuid16): New prototypes.
* linux/dummy.h (sys_geteuid16): Alias to sys_getuid16.
(sys_getegid16, sys_getgid16, sys_getresgid16, sys_setfsgid16,
sys_setgid16, sys_setregid16, sys_setresgid16): Alias to corresponding
sys_*uid16 functions.
* uid.c: Stop including <asm/posix_types.h>.
Parametrize uid_t and names of all exported functions.
(get_print_uid): New function.
(sys_getresuid): Use it.
(printuid): Check for (uid_t) -1.
* uid16.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* linux/arm/syscallent.h: Use sys_chown16, sys_fchown16, sys_getegid16,
sys_geteuid16, sys_getgid16, sys_getresgid16, sys_getresuid16,
sys_getuid16, sys_setfsgid16, sys_setfsuid16, sys_setgid16,
sys_setregid16, sys_setresgid16, sys_setresuid16, sys_setreuid16,
