- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

POSIX.1-2008 moved some constants from the XSI option to the Base.

Fix some _POSIX minimum/maximum values in limits.h:
* Some values changed in POSIX.1-2001; provide the former value if a program
requests compliance to an earlier version of POSIX. [1]
* Add missing _POSIX_CLOCKRES_MIN constant. This is a maximum value but
otherwise works the same as the minimum values.

Correct value for _POSIX_AIO_LISTIO_MAX in <limits.h>.

All the "Minimum Values" (POSIX.1-2008 XBD 13 Headers <limits.h>) are now
correct. These should all be exactly as they are in the specification; the
possibly higher values we support are announced differently.

Deprecate machine/limits.h in favor of new sys/limits.h.
Change all in-tree consumers to include <sys/limits.h>

Discussed on: standards@
Partially submitted by: Craig Rodrigues <rodrigc@attbi.com>

MB_LEN_MAX is not MD, move it to the MI limits.h.

Update limits and configuration parameters for 1003.1/TC1/D6.
Implement new sysconf keys. Change the implenentation of
_SC_ASYNCHRONOUS_IO in preparation for the next set of changes.

Move some limits which had been in <sys/syslimits.h> to <limits.h> where
they belong. They had only ever been in syslimits.h to provide for the
kernel implementation of the CTL_USER MIB branch, which went away with
newsysctl years ago. (There is a #error in <sys/syslimits.h> which I
will downgrade in the next commit.)

Whitespace fixes (mainly for a space instead of a tab after #define).

Use new visibility macros. (1 of 5)

After one too many PRs on the subject, bite the bullet and define IOV_MAX
and its associated constants. Implement _SC_IOV_MAX in the usual way.
Be a bit sloppy about the namespace question; this should get cleared up
in time for 5.0.

Finish _POSIX_PRIORITY_SCHEDULING. Needs P1003_1B and
_KPOSIX_PRIORITY_SCHEDULING options to work. Changes:

Change all "posix4" to "p1003_1b". Misnamed files are left
as "posix4" until I'm told if I can simply delete them and add
new ones;

Add _POSIX_PRIORITY_SCHEDULING system calls for FreeBSD and Linux;

Add man pages for _POSIX_PRIORITY_SCHEDULING system calls;

Add options to LINT;

Minor fixes to P1003_1B code during testing.

Remove AIO_LISTIO_MAX until it is done properly.

Changes to support building with _POSIX_SOURCE set to 199309L:

1. Add sys/_posix.h to handle those preprocessor defs that POSIX
says have effects when defined before including any header files;

2. Change POSIX4_VISIBLE back to _POSIX4_VISIBLE

3. Add _POSIX4_VISIBLE_HISTORICALLY for pre-existing BSD features now
defined in POSIX. These show up when:

_POSIX_SOURCE and _POSIX_C_SOURCE are not set or
_POSIX_C_SOURCE is set >= 199309L

and vanish when:

_POSIX_SOURCE is set or _POSIX_C_SOURCE is < 199309L.

4. Explain these in man 9 posix4;

5. Include _posix.h and conditionalize on new feature test.

POSIX.4 headers and sysctl variables. Nothing should change
unless POSIX4 is defined or _POSIX_VERSION is set to 199309.

Don't include sys/syslimits.h if _ANSI_SOURCE is defined.

Fixed some style bugs.

Change XOPEN constants to match FreeBSD reality and add some
comments to describe them

Activate _POSIX_* stuff if !_ANSI_SOURCE
Add _XOPEN constants set, needed mainly to sense position arguments
in printf (vi cares at this moment)
