Update from Gnulib

Browse source 
Make the following changes by hand, and run 'admin/merge-gnulib'.
* .gitignore: Add lib/malloc/*.gl.h.
* admin/merge-gnulib: Copy lib/af_alg.h and lib/save-cwd.h
directly from Gnulib, without worrying about Gnulib modules,
as these files are special cases.
(AVOIDED_MODULES): Remove malloc-posix.
* lib/malloc.c, lib/realloc.c, m4/malloc.m4, m4/realloc.m4:
* m4/year2038.m4: New files, copied from Gnulib.
* lib/malloca.c, lib/malloca.h:
* m4/close-stream.m4, m4/glibc21.m4, m4/malloca.m4:
Remove.  These are either no longer present in Gnulib, or are no
longer needed by modules that Emacs uses.
* oldXMenu/AddPane.c, oldXmenu/Addsel.c: Include XmenuInt.h first;
needed for new Gnulib.
* src/xmenu.c: Call emacs_abort, not abort.

% @multitable ... @end multitable will make as many columns as desired.
% Contents of each column will wrap at width given in preamble. Width
% can be specified either with sample text given in a template line,
% or in percent of \hsize, the current width of text on page.
% Table can continue over pages but will only break between lines.
% To make preamble:
%
% Either define widths of columns in terms of percent of \hsize:
% @multitable @columnfractions .25 .3 .45
% @item ...
%
% Numbers following @columnfractions are the percent of the total
% current hsize to be used for each column. You may use as many
% columns as desired.
% Or use a template:
% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
% @item ...
% using the widest term desired in each column.
% Each new table line starts with @item, each subsequent new column
% starts with @tab. Empty columns may be produced by supplying @tab's
% with nothing between them for as many times as empty columns are needed,
% ie, @tab@tab@tab will produce two empty columns.
% @item, @tab do not need to be on their own lines, but it will not hurt
% if they are.
% Sample multitable:
% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
% @item first col stuff @tab second col stuff @tab third col
% @item
% first col stuff
% @tab
% second col stuff
% @tab
% third col
% @item first col stuff @tab second col stuff
% @tab Many paragraphs of text may be used in any column.
%
% They will wrap at the width determined by the template.
% @item@tab@tab This will be in third column.
% @end multitable
% Default dimensions may be reset by user.
% @multitableparskip is vertical space between paragraphs in table.
% @multitableparindent is paragraph indent in table.
% @multitablecolmargin is horizontal space to be left between columns.
% @multitablelinespace is space to leave between table items, baseline
% to baseline.
% 0pt means it depends on current normal line spacing.

DYNARRAY_STRUCT
The struct tag of dynamic array to be defined.
DYNARRAY_ELEMENT
The type name of the element type. Elements are copied
as if by memcpy, and can change address as the dynamic
array grows.
DYNARRAY_PREFIX
The prefix of the functions which are defined.
The following parameters are optional:
DYNARRAY_ELEMENT_FREE
DYNARRAY_ELEMENT_FREE (E) is evaluated to deallocate the
contents of elements. E is of type DYNARRAY_ELEMENT *.
DYNARRAY_ELEMENT_INIT
DYNARRAY_ELEMENT_INIT (E) is evaluated to initialize a new
element. E is of type DYNARRAY_ELEMENT *.
If DYNARRAY_ELEMENT_FREE but not DYNARRAY_ELEMENT_INIT is
defined, new elements are automatically zero-initialized.
Otherwise, new elements have undefined contents.
DYNARRAY_INITIAL_SIZE
The size of the statically allocated array (default:
at least 2, more elements if they fit into 128 bytes).
Must be a preprocessor constant. If DYNARRAY_INITIAL_SIZE is 0,
there is no statically allocated array at, and all non-empty
arrays are heap-allocated.
DYNARRAY_FINAL_TYPE
The name of the type which holds the final array. If not
defined, is PREFIX##finalize not provided. DYNARRAY_FINAL_TYPE
must be a struct type, with members of type DYNARRAY_ELEMENT and
size_t at the start (in this order).
These macros are undefined after this header file has been
included.

dynarray implementation):

See above. See above.
Why not use 'ssize_t'?
* 'ptrdiff_t' is more portable; it is standardized by ISO C
whereas 'ssize_t' is standardized only by POSIX.
* 'ssize_t' is not required to be as wide as 'size_t', and some
now-obsolete POSIX platforms had 'size_t' wider than 'ssize_t'.
* Conversely, some now-obsolete platforms had 'ptrdiff_t' wider
than 'size_t', which can be a win and conforms to POSIX.
Won't this cause a problem with objects larger than PTRDIFF_MAX?
* Typical modern or large platforms do not allocate such objects,
so this is not much of a problem in practice; for example, you
can safely write 'idx_t len = strlen (s);'. To port to older
small platforms where allocations larger than PTRDIFF_MAX could
in theory be a problem, you can use Gnulib's ialloc module, or
functions like ximalloc in Gnulib's xalloc module.
Why not use 'ptrdiff_t' directly? Why not use 'ptrdiff_t' directly?
