Current implementation of -qq does not allow suppressing exit status
messages without suppressing signal delivery messages, which is not
good. There is a traditional "-e signal=none" syntax that can be used
to suppress all signal delivery messages.
This partially reverts commit v4.7-222-g01997cf.
* strace.c (trace): Do not suppress signal delivery messages with -qq.
* strace.1: Update documentation about -qq option.
As of glibc 2.16, "struct siginfo" is no longer supported,
and "siginfo_t" must be used instead.

These flags support functionality in mmap() that has not been
pushed back to the community, and which may or may not eventually
end up being the final community model. In the interim, having
these flags unconditionally present for "#ifdef TILE" just means
that the TILE build breaks if using the community versions of
the kernel and glibc, so just revert the code until such time
as it may end up in the community.

On NOMMU systems in "strace PROG" case, we have no way to attach to
the tracee before it calls execve unless in -D mode. That is, the
first execve call is very likely to be missed, and setting
hide_log_until_execve just results to empty log.
* strace.c (init) [NOMMU_SYSTEM]: Do not set hide_log_until_execve
unless in -D mode.
* strace.c [HAVE_PRCTL]: Include sys/prctl.h.
(startup_child) [HAVE_PRCTL && PR_SET_PTRACER && PR_SET_PTRACER_ANY]:
In -D mode, allow tracing the process that is going to become the
tracee.
Tested with "./strace [-D] [-q] [-bexecve] env true",
all cases seem to work.
* defs.h: Declare new variable: bool hide_log_until_execve.
* strace.c: Define hide_log_until_execve.
Rename skip_startup_execve to skip_one_b_execve.
(startup_child): Do not set skip_one_b_execve = 1 here.
(init): If "strace PROG" case (as opposed to "strace -pPID"),
set skip_one_b_execve and hide_log_until_execve to 1.
(trace): Don't print signal messages if hide_log_until_execve == 1.
* syscall.c (trace_syscall_entering):
Skip syscall printing if hide_log_until_execve == 1.
Reset hide_log_until_execve if we enter execve syscall.
(trace_syscall_exiting): Skip syscall printing if hide_log_until_execve == 1.

Even with the -q flag specified, tracing output is still mixed
with messages about signals and process exit status, which is
often irrelevant. Allow the -q option to be repeated to force
the suppression of signals / exit status info too.
* defs.h: Change 'qflag' from 'bool' to 'unsigned int'.
* strace.1: Document ability to repeat '-q' option.
* strace.c: Allow '-q' to be repeated to quieten process
exit status and signal messages.

The recent commit (2690fadc8b35190dddd29274a7405bac13adc469) shuffled
the mips headers around causing it to check the ABI defines before it
included the header which set those up. Now all mips builds fail with:

Newer Linux architectures don't support the stat/stat64 syscalls.
Instead they use fstatat() with AT_FDCWD and an extra flags argument.
Support seeing this output in the 'strace -efile' test.
As part of this change, use "grep -E -x" syntax consistently for
all stat tests, since the number of \(foo\)\? expressions was becoming
pretty unwieldy.

that use fstatat instead. Use "grep -E -x" syntax consistently.
