dumping and the system malloc after dumping.  (Bug#18222)

* configure.ac (HYBRID_MALLOC): New macro; define to use gmalloc
before dumping and the system malloc after dumping.  Define on Cygwin.

Define as macros, expanding to hybrid_malloc, etc.
(HYBRID_GET_CURRENT_DIR_NAME): New macro.
(get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]: Define as
macro.
* src/gmalloc.c: Set up the infrastructure for HYBRID_MALLOC, with a
full implementation on Cygwin.  Remove Cygwin-specific code that
is no longer needed.

Redefine as macros expanding to gmalloc, grealloc, etc.
(DUMPED, ALLOCATED_BEFORE_DUMPING) [CYGWIN]: New macros.
(get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]: Undefine.

HAVE_POSIX_MEMALIGN)]: Define.
(refill_memory_reserve) [HYBRID_MALLOC]: Do nothing.
* src/sysdep.c (get_current_dir_name) [HYBRID_GET_CURRENT_DIR_NAME]:
Define as macro, expanding to gget_current_dir_name, and define
the latter.
* src/emacs.c (main) [HYBRID_MALLOC]: Don't call memory_warnings() or
malloc_enable_thread().  Don't initialize malloc.
* src/lisp.h (NONPOINTER_BITS) [CYGWIN]: Define (because GNU_MALLOC is
no longer defined on Cygwin).
(refill_memory_reserve) [HYBRID_MALLOC]: Don't declare.

that of the thumb).

return entire range (the scaled size of the scroll bar minus
that of the slider).  In `portion' return the scaled position of
the slider.

bar broken in change from 2014-07-27.

 src/syntax.c (scan_lists): Don't examine positions before BEGV.

* configure.ac (newlocale): Check for this, not for uselocale.
* src/sysdep.c (LC_COLLATE, LC_COLLATE_MASK, freelocale, locale_t)
(newlocale, wcscoll_l): Define substitutes for platforms that
lack them, so as to simplify the mainline code.
(str_collate): Simplify the code by assuming the above definitions.
Use wcscoll_l, not uselocale, as uselocale is too fragile.  For
example, the old version left the Emacs in the wrong locale if
wcscoll reported an error.  Use 'int', not ptrdiff_t, for the int
result.  Report an error if newlocale fails.

Fixes: debbugs:18051

* sysdep.c (str_collate): Return int.
(str_collate) [__STDC_ISO_10646__]: Propagate error of wcscoll.

Vinternal__top_level_message, as suggested by Stefan Monnier in
http://lists.gnu.org/archive/html/emacs-devel/2014-08/msg00493.html
All related users changed.

 Manuel Guerrero <juan.guerrero@gmx.de>.

 src/conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Don't define.

Fixes: debbugs:18309

* net/shr.el (shr-copy-url): Encode copied URL to avoid getting
URLs containing spaces and the like.

setlocale succeeds.  Remove unnecessary test before restoring
locale via setlocale, and free the copied setlocale string
when done with it.
