hashfn result here.  Check hash-equality before calling cmpfn.

(js--filling-paragraph): New var.
(js-c-fill-paragraph): Bind it instead of letf-ing the functions.
* lisp/subr.el (locate-user-emacs-file): If both old and new name exist, use
the new name.
* lisp/files.el (hack-one-local-variable--obsolete): New function.
(hack-one-local-variable): Use it for obsolete settings.
nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
* image.c (xpm_make_color_table_h): Fix compiler error because
make_hash_table changed.
* src/xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)

Remove unused vars.
Use same hash function for hashfn_profiler as for hash_string etc.

* lisp.h (sxhash_combine): New inline function, with the contents
of the old SXHASH_COMBINE.
* profiler.c (hashfn_profiler): Use it, instead of having a
special hash function containing a comparison that always yields 1.

* src/fns.c (hashfn_eq, hashfn_eql, sxhash):
* src/profiler.c (hashfn_profiler): Don't use XUINT on non-integers.

* lisp/progmodes/sql.el (sql--make-help-docstring): New function, extracted
from sql-help.
(sql-help): Use it with dynamic-docstring-function.
* ses.el: Use hash map for getting named cells coordinates.
 symbol to coordinate mapping is made by symbol property
 `ses-cell'. This means that the same mapping is done for all SES
 sheets. That is good enough for cells with standard A1 names, but
 not for named cell. So a hash map is added for those
 latter.
 (defconst ses-localvars): added local variable ses--named-cell-hashmap
 (ses-sym-rowcol): Use hashmap for named cell.
 (ses-is-cell-sym-p): New defun.
 (ses-decode-cell-symbol): New defun.
 (ses-create-cell-variable): Add cell to hashmap when name is not A1-like.
 (ses-rename-cell): Check that cell new name is not already in
 spreadsheet with the use of ses-is-cell-sym-p
 (ses-rename-cell): Use hash map for named cells, but accept also
 renaming back to A1-like.
* nsfont.m (ns_descriptor_to_entity): Qcondesed and Qexpanded has
been removed, so remove them here also.
Tweak last vectorlike_header change.
* alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
vectorlike object on the free list.  This is introduced to avoid
some (but not all) pointer casting and aliasing problems, see
http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
* .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
objects.
(xvectype, xvecsize): Use them to examine Lisp_Object values.
Fix recently introduced crash on MS-Windows (Bug#12839).
* w32term.h (struct scroll_bar): Use convenient header.
(SCROLL_BAR_VEC_SIZE): Remove.
* w32term.c (x_scroll_bar_create): Use VECSIZE.

(syms_of_nsfont): Defsym Qcondensed, Qexpanded.
* lisp/emacs-lisp/bytecomp.el (byte-compile-out-toplevel): Don't turn
(funcall '(lambda ..) ..) into ((lambda ..) ..).
* image.c (xpm_make_color_table_h): Change to hashtest_equal.
