This allows for the situation where reaper has children but not
descendands and the too strict asserts in the reap_status() fire.
Remove the wrong asserts, add some clarification for the situation to
the procctl(2) REAP_STATUS.

Distinguish between WRDE_BADVAL and WRDE_SYNTAX based on when the error
occurred (parsing or execution), not based on whether WRDE_UNDEF was passed.
Also, return WRDE_NOSPACE for a few more unexpected results from sh.
- Remove the redundant _PATH_RSH definition (paths.h at r96194);
- Use pid_t for PIDs
- Note that we are at the same level of OpenBSD's counterpart of
revision 1.7 (r94757).

The functionality of the wordexp builtin is easily replaced using normal
shell code, although performance is slightly worse.
This does not mean that wordexp() will remain shell-independent -- a fully
reliable implementation of WRDE_NOCMD is really only possible using
extensions to the shell, or by adding much of the shell's code to libc.
The comment in the libc/sys symbol map referenced the generated symbols
for the syscall trampolines. Such comment was out of place in the secure
symbol map so remove the stale comment and attempt to clarify the old one
to avoid risks of confusion.

As part of the code refactoring to support FORTIFY_SOURCE we want
a new subdirectory "secure" to keep the files related to security.
Move the stack protector functions to this new directory.

In fact, it doesn't even work with single-byte codesets like ISO-8859-1.
The comparison blows up at index 128 (the range is 0 to UCHAR_MAX (255).
As a temporary workaround, all comparisons will be done in C locale
regardless of the environment setting. The regex library needs to be
updated to handle all codesets.

packed LC_COLLATE binary formats. These were generated with the colldef
tool, but the new LC_COLLATE files are going to be generated by the new
localedef tool using CLDR POSIX files as input. The BSD-flavored
version of localedef identifies the format as "BSD 1.0". Any
LC_COLLATE file with a different version will simply not be loaded, and
all LC* categories will get set to "C" (aka "POSIX") locale.
This work is based off of Nexenta's contribution to Illumos.
The integration with xlocale is John Marino's work for Dragonfly.
The following commits will enable localedef tool, disable the colldef
tool, add generated colldef directory, and finally remove colldef from
base.
The only difference with Dragonfly are:
- a few fixes to build with clang
- And identification of the flavor as "BSD 1.0" instead of "Dragonfly 4.4"

It looks like EVFILT_READ and EVFILT_WRITE trigger under the same
conditions as poll()'s POLLRDNORM and POLLWRNORM as described by POSIX.
The only difference is that POLLRDNORM has to be triggered on regular
files unconditionally, whereas EVFILT_READ only triggers when not EOF.
Introduce a new flag, NOTE_FILE_POLL, that can be used to make
EVFILT_READ and EVFILT_WRITE behave identically to poll(). This flag
will be used by cloudlibc's poll() function.

Summary:
Back in 2005, maxim@ attempted to fix shutdown() to return ENOTCONN in case the socket was not connected (r150152). This had to be rolled back (r150155), as it broke some of the existing programs that depend on this behavior. I reapplied this change on my system and indeed, syslogd failed to start up. I fixed this back in February (279016) and MFC'ed it to the supported stable branches. Apart from that, things seem to work out all right.
Since at least Linux and Mac OS X do the right thing, I'd like to go ahead and give this another try. To keep old copies of syslogd working, only start returning ENOTCONN for recent binaries.
I took a look at the XNU sources and they seem to test against both SS_ISCONNECTED, SS_ISCONNECTING and SS_ISDISCONNECTING, instead of just SS_ISCONNECTED. That seams reasonable, so let's do the same.
Test Plan:
This issue was uncovered while writing tests for shutdown() in CloudABI:
