Use recently added attributes in few standard headers.

There attributes are to assits compiler making better analysis
doring compilation time. Like branch prediction and hinting.

While there, for now prefer to use __attribute__((__noreturn__)) to
_Noreturn, since neither OpenBSD or NetBSD has it at all and in our
variant we don't handle it in c++ case ([[noreturn]]) anyway.
Looks to be only a workaround for some old clang++ version.

<string.h>: Fix vkernel build.

Fix visibility of various functions in a number of headers.

The following functions were moved from XSI into the base with
POSIX 200809:

catclose(), catgets(), catopen(), dlclose(), dlerror(), dlopen(),
dlsym(), fchdir(), getpgid(), getsid(), getsubopt(), iconv(),
iconv_close(), iconv_open(), lchown(), mkstemp(), nl_langinfo(),
poll(), pread(), pwrite(), strdup(), strfmon(), tcgetsid(),
truncate(), and waitid().

This commit adjusts our headers to reflect that, i.e. specifying
_POSIX_C_SOURCE=200809 is now enough to expose their prototypes.

The checking of __XSI_VISIBLE's value (ranges) for XSI functions
could certainly be better (generally in our headers).

Also, we don't yet have waitid().

This change was build tested with around 8000 ports (until the
bulk build choked on a jdk7 memory leak (I suppose) while building
textproc/fop). The glibc conformance test suite thinks this
commit is correct, too.

locales, libconv: Sync with FreeBSD (extensive reach)

What started out as a relatively simply upgrade to libiconv finally
resulted in a simultaneous overhaul to locales, strings, and stdio.
All of these are interdependent and there is no way to upgrade them
individually or in steps.

These cases are similar to what happened with libm where significant
syncing came from NetBSD previously, rendering contributions from
FreeBSD difficult. Libiconv and locales (both ancient) are now in
sync with FreeBSD HEAD.

As several headers were signficantly updated and the mtree was updated
to accommodate the new include/xlocale directory, this commit will
require a full world build. It also may cause some dports to no longer
build due to prototype differences, but the dports will be adjusted.

The regexp library was not being used. It was removed from FreeBSD four
years ago. Since it required collate updates, I took the opportunity to
remove it completely by adding re_comp functionality to 4.3 compat
library like FreeBSD did.

__DragonFly_version has been bumped to 500300.

* The existing SHA backends have been shown to be more susceptible to brute-

http://www.openwall.com/lists/oss-security/2012/01/16/2

* Bring in the reference implementation used in Linux, code is in the public
domain.

* Add required (standard) functions mempcpy and stpcpy.

* Change default for future installs to SHA512, this is the default on at
least archlinux and fedora.

* Add some minor hacks to libcrypt/crypt.c to ensure that
a) All existing passwords continue to work
b) All future passwords will be more secure with no changes required

* To update passwords to the new format use passwd(1) for each user, and to
change your default password type to SHA512 (default for new installations)
change the passwd_format setting under default to "sha512".

strrchr().

-Remove advertising clause from copyrights.

-Add memmem() which is basically the same as strstr().

-Add stpcpy().

-Add a SECURITY CONSIDERATIONS section to remind people about buffer
overflows, etc.

-Add restrict keyword where required.

-Add strndup().

-Correctly document the return value of strerror() and strerror_r() and
the contents of the returned buffer for unknown error codes.

-Add NLS catalogs support to strerror(), strerror_r() and strsignal().
Controlled by NLS define.

-For strl* files, use a less restrictive copyright (original author
changed it).

-strmode.3: strmode does not return 0.

-Move swab()'s prototype to unistd.h IAW SUS.

-Simplify by removing unneeded local variables and explicit
null termination is wcs* functions.

-Move wcscoll() and wcsxfrm() to string/ and do locale-sensitive
collation for single-byte locales.

-Add wcsdup().

-Remove unneeded includes.

-Reimplement wcsrchr(3) more efficiently, using a single forward scan
(like strrchr(3)) instead of scanning forwards to find the end of the
string then scanning backwards to find the character.

-Slightly optimize wcswidth().

-Tell contrib srcs that we have strndup now since some of them provide
their own static definition which will blow up a buildworld.
