Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.

(sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
Use it instead of discarding useful hash info with large hash values.

(MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK): Rewrite
to use FIXNUM_BITS, as this simplifies things.
(next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
Adjust signatures to match updated version of code.
(consing_since_gc): Now EMACS_INT, since a single hash table can
use more than INT_MAX bytes.

syms_of_callproc does the same thing.  Remove test for
"initialized", do it in the caller.

Malloc failure behavior now depends on size of allocation.
* lib/allocator.h (struct allocator.die): New size arg.
* lib/careadlinkat.c (careadlinkat): Pass size to 'die' function.
If the actual problem is an ssize_t limitation, not a size_t or
malloc failure, fail with errno == ENAMETOOLONG instead of calling 'die'.
[src/ChangeLog]
Malloc failure behavior now depends on size of allocation.
* alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
* lisp.h: Change signatures accordingly.
* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
All callers changed.

Without this change, the gnutls library would invoke malloc etc.
directly, which causes problems on non-SYNC_INPUT hosts, and which
runs afoul of improving memory_full behavior.
(fn_gnutls_global_set_mem_functions): New macro or function pointer.
(emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
xfree instead of the default malloc, realloc, free.
(Fgnutls_boot): No need to check for memory allocation failure,
since xmalloc does that for us.

* lisp.h (Qdebug): Remove decl.  This reverts a part of the
2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
2011-04-14T06:48:41Z!eggert@cs.ucla.edu.

(imagemagick-register-types): Doc fix.

* src/image.c: Various fixes to ImageMagick code comments.
(Fimagemagick_types): Doc fix.

* xselect.c (converted_selections, conversion_fail_tag): Now static.

(x_clipboard_manager_save_all): Move extern decl to ...
* xterm.h: ... here, so that it can be checked for consistency.

* lisp/select.el: Don't perform clipboard-manager saving in hooks;
leave the hooks empty.

* src/emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
* src/frame.c (delete_frame): Call x_clipboard_manager_save_frame.

* src/xselect.c (x_clipboard_manager_save_frame)
(x_clipboard_manager_save_all): New functions.
(Fx_clipboard_manager_save): Lisp function deleted.

* src/xterm.h: Update prototype.
