with one of the timer thread FDs, the internal FD is diverted.
[Bug #11336] [ruby-core:69886] [Bug #11350] [ruby-core:69961]
* process.c (dup2_with_divert): new function for the above purpose.
* thread_pthread.c (rb_divert_reserved_fd): new function for
diverting reserved FD. If the given FD is the same as one of the
reserved FDs, the reserved FD number is internally changed.
It returns -1 when error. Otherwise, returns 0. It also returns
0 if there is no need to change reserved FD number.
* thread_win32.c (rb_divert_reserved_fd): always returns 0 because
of no reserved FDs.
* internal.h (rb_divert_reserved_fd): prototype declaration.
It is Ruby internal use only.

reserved FD. It should be closed in the exec system call due to the
O_CLOEXEC or FD_CLOEXEC flag. [Bug #11353] [ruby-core:69977]
* process.c (close_unless_reserved): new function to close FD unless
it is reserved for internal communication.
* thread_pthread.c (rb_reserved_fd_p): should check owner_process pid
to avoid false positive in forked child process.

to generate envp_str anytime on Solaris 10 (or earlier version
of Solaris) to avoid calling execv() which is async-signal unsafe
on Solaris 10. [Bug #11265] [ruby-dev:49089]
* process.c (exec_with_sh, proc_exec_cmd): On Solaris 10,
because ALWAYS_NEED_ENVP is 1 and envp_str is always generated,
execv() in exec_with_sh() and proc_exec_cmd() are never called.
To guarantee this, execv() is replaced by a macro to print
out error message on Solaris 10.
* process.c (proc_exec_sh): Because proc_exec_sh() may be called
by rb_proc_exec() with envp_str = Qfalse, execl() is replaced
by a macro that calls execle() with "extern char **environ"
traditional global variable on Solaris 10.
TODO: This may be unsafe and sholud be changed
in the future.
Although rb_proc_exec() is not used from inside current version
of ruby, it may be called by third-party extensions.

Note: Some of the fixes are for newlib in general but not NaCl-specific.
* include/ruby/intern.h (rb_fd_select): declare struct timeval, or the
struct gets local to the function in C99.
* file.c (#include): add nacl/stat.h for PNaCl.
(utimes): added a declaration for PNaCl.
(stat_atimespec): stat::st_atimensec is long long but
timespec::tv_nsec is long in PNaCl.
(stat_mtimespec, stat_ctimespec): ditto.
(rb_group_member): disable getgroups unless HAVE_GETGROUPS.
(eaccess): unify the fallback to generic defined(USE_GETEUID).
* io.c: include sys/time.h for struct timeval.
(rb_close_before_exec): nothing we can do if F_GETFD is not
available.
(ioctl): pnacl newlib actually doesn't have ioctl.
* process.c (maxgroups): it is used iff
defined(_SC_NGROUPS_MAX) || defined(NGROUPS_MAX) but not
defined(HAVE_GETGROUPS) || defined(HAVE_SETGROUPS).
(obj2gid): fail unless the object is a Fixnum if getgrnam is not
available.
(disable_child_handler_fork_child): sigaction is not available in
PNaCl newlib.
* configure.in (warnflags, strict_warnflags): avoid -ansi for strlcpy.
(rb_cv_gcc_atomic_builtins): also check
__atomic_or_etch because it is used in ruby_atomic.h.
(rb_cv_gcc_sync_builtins): ditto.
(HAVE_GETGRNAM): added.
