vasilito b8aac3c9bc D7: editor multi-cursor support 
Add secondary_cursors field to Editor with insert_char_multi,
delete_back_multi, delete_forward_multi methods. Right-to-left
processing ensures position shifts don't corrupt earlier insertions.

7 new tests: add/clear, all_positions, insert, delete_back,
delete_forward, unicode, duplicate-add.

Suppress extern inline with HP-UX cc, as it appears to be broken; see
<http://lists.gnu.org/archive/html/bug-texinfo/2013-02/msg00030.html>.
Suppress extern inline with Sun C in standards-conformance mode, as it
mishandles inline functions that call each other. E.g., for 'inline void f
(void) { } inline void g (void) { f (); }', c99 incorrectly complains
'reference to static identifier "f" in extern inline function'.
This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
on configurations that mistakenly use 'static inline' to implement
functions or macros in standard C headers like <ctype.h>. For example,
if isdigit is mistakenly implemented via a static inline function,
a program containing an extern inline function that calls isdigit
may not work since the C standard prohibits extern inline functions
from calling static functions. This bug is known to occur on:
OS X 10.8 and earlier; see:
http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00023.html
DragonFly; see
http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log
FreeBSD; see:
http://lists.gnu.org/archive/html/bug-gnulib/2014-07/msg00104.html
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <http://trac.macports.org/ticket/41033>.

dnl for the builtin va_copy to work. With Autoconf 2.60 or later,
