update doc regarding Solaris 11

[Bruno Haible]

About a month ago, Solaris 11 Express was released. It's something like a beta
of Solaris 11 that is scheduled to be released in 2011. It's the successor
(from the Oracle side) of the OpenSolaris project; maybe we'll also have
to consider Illumos / OpenIndiana in the future.

I'm updating the documentation, replacing many mentions of "Solaris 10"
by "Solaris 11 2010-11".

        Update for Solaris 11 2010-11.
        * doc/{glibc,posix}-{functions,headers}: Add info about Solaris 11
        Express, released in November 2010.

More important than the changes are the places that have not changed, that
is, the bugs which have been fixed and the functions which have been added,
compared to Solaris 10.

New features:

<libintl.h> now supports also the 2002 revision of GNU .mo files.

Bug fixes:

<stdio.h> now defines ssize_t.
<math.h> now defines NAN and HUGE_VAL to usable values.
getopt_long and getopt_long_only support the '+' flag.
The *printf functions support precisions larger than 512.
