* configure.ac (HAVE_RSVG): Move after cairo.
(USE_CAIRO): Disable rsvg, don't disable Xpm.

(xpm_load): Convert simple Xpms (32 bit ZPixmap) to CAIRO_FORMAT_ARGB32
and create a surface.

* src/xterm.c (x_update_begin): Don't create any surface for non-visible
tip frames, the geometry may be wrong.

* src/xterm.c (handle_one_xevent): Always redraw tool tips on
MapNotify.  Update tool tip frame sizes on ConfigureNotify.

 src/keyboard.c (read_key_sequence): Don't let
 this_single_command_key_start become negative.

* xterm.c (x_display_ok, x_term_init): Block SIGIO when opening
a display.

* xsmfns.c (smc_save_yourself_CB): Return if Vinvocation_name or
user_login_name are not strings.

 blocking connections.

Derived from a bug report by Nicolas Richard in:
http://bugs.gnu.org/20191#20
* xsmfns.c (smc_save_yourself_CB): Don't dump core if
invocation-name is not a string.  Initialize user-login-name if it
is not already initialized, and don't dump core if it is not a
string.
(create_client_leader_window): Don't dump core if x-resource-name
and x-resource-class are not both strings.
(x_session_initialize): Don't dump core if x-session-previous-id,
invocation-directory, and invocation-name are not strings.

* editfns.c (Fuser_login_name, Fuser_real_login_name)
(syms_of_editfns): Don't rely on all-bits-zero being an Elisp integer,
as this is no longer true now that Qnil == 0.

From a suggestion by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2015-03/msg00824.html
* process.c (NON_BLOCKING_CONNECT): Simplify by assuming that
BROKEN_NON_BLOCKING_CONNECT is not defined.
(SELECT_CAN_DO_WRITE_MASK): Remove, and assume it's now true.

 src/lread.c (substitute_object_recurse): For sub-char-tables, start
 the recursive SUBSTITUTE loop from index of 2, to skip the
 non-Lisp members of the sub-char-table.  See the discussion at
 http://lists.gnu.org/archive/html/emacs-devel/2015-03/msg00520.html
 for the details.

 Based on ideas from Kim F. Storm <storm@cua.dk>, see
 http://lists.gnu.org/archive/html/emacs-devel/2006-12/msg00873.html.

 src/w32proc.c (reader_thread): If the FILE_CONNECT flag is set, call
 '_sys_wait_connect'.  If it returns STATUS_CONNECT_FAILED, exit
 the thread with code 2.
 (sys_select): Support 'wfds' in addition to 'rfds'.  If a
 descriptor in 'wfds' has its bit set, but the corresponding
 fd_info member doesn't have its FILE_CONNECT flag set, ignore the
 descriptor.  Otherwise, acknowledge a successful non-blocking
 connect by resetting the FILE_CONNECT flag and setting cp->status
 to STATUS_READ_ACKNOWLEDGED.
 src/w32.h (STATUS_CONNECT_FAILED): New enumeration value.
 (struct _child_process): New member 'errcode'.
 (FILE_CONNECT): New flag.
 (_sys_wait_connect): Add prototype.
 src/w32.c (pfn_WSAEnumNetworkEvents): New function pointer.
 (init_winsock): Load WSAEnumNetworkEvents from winsock DLL.
 (set_errno): Map WSAEWOULDBLOCK and WSAENOTCONN.
 (sys_connect): Support non-blocking 'connect' calls by setting the
 FILE_CONNECT flag in the fd_info member and returning EINPROGRESS.
 (_sys_read_ahead): Add debug message if this function is called
 for a descriptor that waits for a non-blocking connect to complete.
 (_sys_wait_connect): New function.
 (sys_read): Support STATUS_CONNECT_FAILED.  Return the error code
 recorded by _sys_wait_connect when the non-blocking connect
 failed.  Don't call WSAGetLastError before a call to set_errno had
 a chance to use its value, since WSAGetLastError clears the last
 error.

 nt/inc/ms-w32.h (BROKEN_NON_BLOCKING_CONNECT): Don't define.

* src/editfns.c (save_excursion_save): Don't save the mark.
(save_excursion_restore): Don't restore the mark.
(Fsave_excursion): Fix docstring accordingly.

* doc/lispref/positions.texi (Excursions, Narrowing): `save-excursion' does
not save&restore the mark any more.

scroll bar width with GTK3 (Bug#20182).

* doc/lispref/numbers.texi (Float Basics): Improve ldexp documentation.

avoid cast to 'char **', and to reduce indenting and reuse of locals.

* src/process.c (Fmake_process): New function.
(create_process, create_pty): Check p->pty_flag instead of
Vprocess_connection_type.
(syms_of_process): Register QCcommand, QCconnection_type, Qpty,
Qpipe, and Smake_process.  Unregister Sstart_process.

* lisp/subr.el (start-process): New function, ported from the C
implementation.

* doc/lispref/processes.texi (Asynchronous Processes): Mention
`make-process'.

* etc/NEWS: Mention `make-process'.

No need to merge to trunk, since it corrects a backported entry that
should not appear in trunk.

Fixes: debbugs:20156

+ 3 in alloca (tiny change)

* src/fontset.c (fontset_pattern_regexp): Replace + 1 with + 3 for
regexsize.

 src/emacs.c (synchronize_locale) [WINDOWSNT]: Ignore 'category' and

 we are going to load overlays at the beginning of the invisible
 text.
 (setup_for_ellipsis): Reset the ignore_overlay_strings_at_pos_p
 flag also here.

 Jing, Counting Rods, Sundanese, Lepcha, Ol Chiki, Saurashtra,
 Kayah Li, Rejang, Ancient Symbols, Phistos Disc, Carian, Lycian,
 Lydian, Dominoe Tiles, and Mahjong Tiles.  Break the Mathematical
 Alphanumeric Symbols into several "scripts" like fontset.el does.

Fixes: debbugs:19680

 src/w32fns.c <ImmReleaseContext_Proc, ImmSetCompositionWindow_Proc>:
 Fix typedefs to be consistent with the corresponding w32 API
 signatures.
 (w32_wnd_proc) <WM_IME_STARTCOMPOSITION>: Don't invoke
 DefWindowProc if we successfully handled the message, as doing so
 causes problems in displaying selection dialogs.

* sysdep.c (emacs_backtrace): Don't dump core on x86.
Fixes: bug#19959

 src/keyboard.c (make_lispy_position): When the click is on the
 right-side vertical scroll bar, pass the rightmost X coordinate to
 buffer_posn_from_coords, so that the returned text position
 reflects the closest point to the click.  Fixes region extension
 when mouse moves outside the Emacs frame that has scroll bars on
 the right.

unchanged if tool bar size changes with new font.
