When strace is built with large file support definitions in CFLAGS (as

rlim_t even though the struct rlimit fields used by the system call
interface are only 32-bit. The SIZEOF_RLIM_T will then be 8 which
results in bad decoding of the getrlimit and setrlimit syscalls.
This is fixed by replacing unreliable SIZEOF_RLIM_T based checks with
checks for current_wordsize.

OABI is rarely used in ARM EABI systems nowadays, so disable its support
by default. Add --enable-arm-oabi option to enable ARM OABI support.
* configure.ac: New option --enable-arm-oabi.
* syscall.c (get_scno) [ARM]: Check ENABLE_ARM_OABI macro defined by
configure instead of undocumented STRACE_KNOWS_ONLY_EABI macro.
Assume that F_SETLK64, F_SETLKW64, and F_GETLK64 are either defined or
not defined altogether.
Do not assume that sizeof(off_t) < sizeof(long long) when F_SETLK64 is
undefined.
This change fixes build with musl libc on x86.
* configure.ac: Define SIZEOF_OFF_T.
* desc.c (USE_PRINTFLOCK64): New macro.
(struct flock64, printflock64): Do not define on X32.
(printflock): Replace X32 specific workaround with SIZEOF_OFF_T check.
Fix printing off_t members of struct flock.
(sys_fcntl): Use USE_PRINTFLOCK64.
The sigset_t provided by libc is not quite convenient.
In glibc, sigset_t is an array with space for 1024 bits, which is much
more than required: all architectures supported by Linux have only 64
signals except MIPS, which has 128.
In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than
necessary.
With this change, signal mask is decoded without use of intermediate
sigset_t structure, which saves us some cpu cycles in case of glibc with
its inflated sigset_t, and enables build with libcs where sigset_t is
broken.
Old implementation used to check each signal number in the given signal
mask twice using sigismember().
New implementation is based on popcount and next_set_bit() so it's
noticeably faster.
* configure.ac: Check for __builtin_popcount.
* signal.c: Ensure that NSIG >= 32.
(sprintsigmask, sprintsigmask_long, printsigmask): Remove.
(popcount32, sprintsigmask_n): New functions.

(print_sigset_addr_len, sys_sigsetmask, sys_sigreturn, sys_siggetmask,

because it conflicts with libc headers, but SA_RESTORER is needed in

* configure.ac (ASM_SA_RESTORER): Define if SA_RESTORER is defined
in <asm/signal.h>.
* configure.ac (AC_CHECK_TYPES): Add struct flock64.
* desc.c (HAVE_F_SETLK64, HAVE_F_SETLKW64, HAVE_F_GETLK64): New macros.

PTRACE_POKEUSER.
* defs.h: Define PTRACE_PEEKUSER and PTRACE_POKEUSER only if
they are not provided by <sys/ptrace.h>.
Reported by John Spencer.
SIGEV_THREAD_ID decoding requires access to an internal member of
struct sigevent. There seems to be no portable way to do it besides
adding a configure check.
* configure.ac (AC_CHECK_MEMBERS): Check for
struct sigevent._sigev_un._pad and struct sigevent.__pad.
* time.c (printsigevent): Use an appropriate struct sigevent member
to print thread id.
Reported by John Spencer.
Most of the code already uses long long types unconditionally.
* configure.ac: Remove the check for long long.
* file.c (printstat64): Remove HAVE_LONG_LONG checks, use %llu format
string unconditionally.
This change incorporates a partial copy instead
of using external libaio.h.
Why?
Because we want to properly decode 32-bit aio calls
by 64-bit strace. For that, we need more definitions than
libaio.h provides.
(These defs are not done yet, but will eventually be done).
Keeping our local 32-bit compat defs in sync with libaio.h
_without seeing libaio structs_ is hard/more bug prone.
A smaller benefit is that we don't need libaio installed.

Remove non-Linux source directories: freebsd/, svr4/, sunos4/, svr4/.
Remove README-freebsd, README-sunos4, README-svr4, m4/procfs.m4.
linux/sparc/{errnoent1,ioctlent1,signalent1}.h used to point to svr4/ files -
replace their contents with copies of used (and now deleted) files.
Make linux/sparc64/{errnoent1,ioctlent1,signalent1}.h include these files
instead of svr4/* ones.
Makefile.am: remove references to deleted files.
configure.ac: Remove a few tests which make no sense on Linux.
Man page: remove non-Linux quirks information.

glibc-2.15 provides process_vm_readv, so trying to provide it ourselves
with that version fails.

PTRACE_O_TRACEEXEC, PTRACE_O_TRACEEXIT, PTRACE_EVENT_EXEC,
PTRACE_EVENT_VFORK_DONE and PTRACE_EVENT_EXIT.
* defs.h [LINUX]: Define these PTRACE_* constants when they are not
provided by <sys/ptrace.h>.

The long long endian detection code does an AC_TRY_RUN() and since that
doesn't work when cross-compiling, it sets a fallback value. However,
rather than do any sort of default endian detection, the code simply
sets it to "no". This probably breaks most little endian systems out
there when cross-compiling for them. It certainly breaks Blackfin
systems. So use the common endian detection code provided by autoconf
and key off of that when cross-compiling.
* configure.ac: Call AC_C_BIGENDIAN.
* m4/long_long.m4 (AC_LITTLE_ENDIAN_LONG_LONG): Set cross-compiling
logic based on ac_cv_c_bigendian.
