2f948b9231 Set PTRACE_O_TRACEEXIT option and handle PTRACE_EVENT_EXIT events
Do not assume that some syscalls do not generate syscall-exit-stops.
When syscalls fail for any reason they may generate syscall-exit-stops.

The solution is to wait for an actual exit reported by PTRACE_EVENT_EXIT
and print the end of unfinished exiting syscall properly.

* exit.c: Remove.
* Makefile.am (strace_SOURCES): Remove exit.c.
* linux/dummy.h (sys_exit): Alias to printargs_d.

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

have different struct stat64.  Rewrite parsers using mpers functionality

80f7db1fed 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,
and sys_setuid16 parsers for *chown and [gs]et*[gu]id syscall entries.
* linux/bfin/syscallent.h: Likewise.
* linux/i386/syscallent.h: Likewise.

* linux/s390/syscallent.h: Likewise.

* linux/sh64/syscallent.h: Likewise.
* tests/uid16.c: New file.
* tests/uid16.test: New test.
* tests/Makefile.am (CHECK_PROGRAMS): Add uid16.
(TESTS): Add uid16.test.
* tests/.gitignore: Add uid16.

907df1e157 Alias sys_setdomainname to sys_sethostname
Since parsers for setdomainname and sethostname syscalls are identical,
replace sys_setdomainname with an alias to sys_sethostname.

* linux/dummy.h (sys_setdomainname): Alias to sys_sethostname.
* linux/syscall.h (sys_setdomainname): Remove.
* process.c (sys_setdomainname): Remove.

37548c4afc Alias sys_getpeername to sys_getsockname
Since parsers for getpeername and getsockname syscalls are identical,
replace sys_getpeername with an alias to sys_getsockname.

* linux/dummy.h (sys_getpeername): Alias to sys_getsockname.
* linux/syscall.h (sys_getpeername): Remove.
* net.c (sys_getpeername): Remove.

8238590c1d Alias sys_stime to sys_time
Since parsers for stime and time syscalls are identical,
replace sys_stime with an alias to sys_time.

* linux/dummy.h (sys_stime): Alias to sys_time.
* linux/syscall.h (sys_stime): Remove.
* time.c (sys_stime): Remove.

6355a1f867 Alias sys_mkdir and sys_mkdirat to sys_chmod and sys_fchmodat
Special parsers for mkdir and mkdirat are redundant because
sys_chmod and sys_fchmodat implement the same decoding.

* file.c (decode_mkdir, sys_mkdir, sys_mkdirat): Remove.
* linux/dummy.h (sys_mkdir): Alias to sys_chmod.
(sys_mkdirat): Alias to sys_fchmodat.
* linux/syscall.h (sys_mkdir, sys_mkdirat): Remove.
* pathtrace.c (pathtrace_match): Do not check for sys_mkdirat.
