* info/dir (File):
* Makefile.in: Add emacs-gnutls to the info directory and the
INFO_FILES target.

* doc/misc/emacs-gnutls.texi: Add documentation for the GnuTLS integration.

* doc/misc/gnutls.texi: New file to explain the GnuTLS integration.

* doc/misc/Makefile.in: Add gnutls.texi to build.

* gnutls.c (gnutls_log_function2i): Convenience log function.
(emacs_gnutls_read): Use new log functions,
`gnutls_handshakes_tried' process member, and
`GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
attempts per process (connection).

* gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.  Add
convenience `GNUTLS_LOG2i' macro.

* process.c (make_process):
* process.h: Add integer `gnutls_handshakes_tried' member to
process struct.

* lisp/apropos.el (apropos-variable):
* lisp/files-x.el (read-file-local-variable):
* lisp/simple.el (set-variable):
* lisp/woman.el (woman-mini-help):
* lisp/emacs-lisp/byte-opt.el (side-effect-free-fns): Callers changed.

* lisp/custom.el (custom-variable-p): Return nil for non-symbol
arguments instead of signaling an error.
(user-variable-p): Obsolete alias for custom-variable-p.

* lisp/erc/erc.el (erc-cmd-SET): Call custom-variable-p instead of
user-variable-p.

* src/callint.c (Finteractive, Fcall_interactively):
* src/minibuf.c (Fread_variable): Callers changed.

(lisp_indirect_variable): Functions deleted.
(Fdefvar): Caller changed.

 src/xdisp.c (set_cursor_from_row): If the display string appears in
 the buffer at position that is closer to point than the position
 after the display string, display the cursor on the first glyph of
 the display string.  Fixes cursor display when a 'display' text
 property immediately follows invisible text.

* lisp/startup.el (normal-top-level):
Don't look for leim-list.el in places where it will not be found.

Fixes: debbugs:910

* composite.c (get_composition_id): Use 'double' consistently
instead of converting 'float' to 'double' and vice versa; this is
easier to understand and avoids a GCC warning.

($(leimdir)/leim-list.el): New rule.
(emacs$(EXEEXT)): Depend on leim-list.el.

Fixes: debbugs:4789

(OTHERS, CHINESE, EASTASIA, ASIA, EUROPEAN, WORLD, NON_TIT_MISC):
Remove variables listing the non-generated .el files.
(.el.elc): Add explicit load-path for quail.
(all): Depend on compile-main rule rather than $WORLD.

Remove guarded calls to ucs-set-table-for-input. 

* src/buffer.c (Qucs_set_table_for_input): Remove.

Eg org.texi has been using 4.7 functions for some time.

Fixes: debbugs:10910

proper alignment.

 lisp/textmodes/ispell.el (ispell-check-version): For hunspell, set
 ispell-encoding8-command to "-i", without a trailing space.
 (ispell-start-process): For hunspell, use '("-i" ENCODING), in 2
 separate command-line arguments, to specify the encoding, since
 that's how hunspell expects it.

This reduces somewhat the number of "rogue" settings in emacs -Q.

Fixes: debbugs:8054

* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
(mark_memory): Mark Lisp_Objects only if pointers might hide in
objects, as mark_maybe_pointer will catch them otherwise.
(GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
* s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

* xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

 about subtle differences between FETCH_CHAR* and STRING_CHAR*
