lisp/emacs-lisp/cl.el (cl--function-convert): Merge cache that cl--labels-convert adds (bug#19699)

Fix inaccuracies in my recent ChangeLog entry.

Allow for adding new members to Tar archives.

* lisp/tar-mode.el: Allow for adding new archive members.
(tar-new-regular-file-header, tar--pad-to, tar--put-at)
(tar-header-serialize): New functions.
(tar-current-position): Split from tar-current-descriptor.
(tar-current-descriptor): Use it.
(tar-new-entry): New command.
(tar-mode-map): Bind it.
* doc/emacs/files.texi (File Archives): Document "I" for tar-new-entry.
* etc/NEWS: Mention the new tar-new-entry command.

Fixes: debbugs:19274

minor tweaks for `python-check'

* lisp/progmodes/python.el (python-check-custom-command): Buffer local
because it usually includes the buffer name.
(python-check-command): Set to epylint when pyflakes is not available.

etc/NEWS: Document EUDC improvements

EUDC: New maintainer

* net/eudcb-bbdb.el, net/eudcb-ldap.el, net/eudcb-mab.el,
net/eudc-bob.el, net/eudcb-ph.el, net/eudc.el, net/eudc-export.el,
net/eudc-hotlist.el, net/eudc-vars.el: New maintainer.

isearch.el (isearch-process-search-char): Add docstring.

Auto-commit of loaddefs files.

lisp/emacs-lisp/derived.el (define-derived-mode): Declare indent 3.

Now, e.g. `indent-sexp' will produce:

    (define-derived-mode outline-mode text-mode "Outline"
      "Set ...")

instead of:

    (define-derived-mode outline-mode text-mode "Outline"
                         "Set ...")

Port autogen.sh hook creation to Apple Git

* autogen.sh: Do not assume that the hook samples exist.
This ports to git version 1.9.3 (Apple Git-50).
For some reason Apple decided to populate the git hooks directory
in a different way from the way that standard Git does it.
The downside is that patch applications won't be checked on Apple,
but that's better than autogen.sh failing.
Problem reported by Sam Steingold in:
http://lists.gnu.org/archive/html/emacs-devel/2015-01/msg00898.html

variables, instead of attempting to infer them individually.
* etc/NEWS: Document this.

Use bool for boolean.

Don't fail if chown or chgrp for 'update-game-score' is unsuccessful.

* lib-src/Makefile.in ($(DESTDIR)${archlibdir}): Don't fail if the
chown or chgrp command is unsuccessful; the 'update-game-score'
program has a fallback for this at runtime.

Spelling fix

Use `cl-defgeneric' and `cl-defmethod' instead of the EIEIO
counterparts.
