* lisp/org-agenda.el: Use lexical-binding

- Removed the global (defvar date) and (defvar entry) so as not to
  conflict with function arguments of that name.  Instead I added such
  `defvar`s in the body of each of the functions where it
  seemed needed.
- I added some FIXMEs for some issues I found along the way.
- Added an `org-dlet` macro, just like I had done for `calendar-dlet`,
  but I also use `defvar` "manually" at some places, when splitting an
  existing `let` into a mix of `let`s and `dlet`s seemed too much trouble.
- Removed uses of `org-let and `org-let2` not only because I consider
  them offensive to my sense of aesthetics but also because they're
  basically incompatible with lexical scoping.
  I replaced them with uses of `cl-progv` which are a bit more verbose.
  Maybe we should define some `org-progv` macro on top of `cl-progv` to
  make the code less verbose, but I didn't do that because I like the
  fact that the current code makes uses of `eval` a bit more obvious
  (since these behave differently with lexical scoping than with
  lexical binding, it seemed worthwhile).
- Removed the use of `eval` in `org-store-agenda-views` which was only
  placed there in order to use a macro before it's defined (it would
  have been simpler/cleaner to just move that functions *after* the
  macro, but with the new code the problem doesn't occur any more anyway).
- Replaced a few `(lambda...) with actual closures.

Detailed changes follow:

(date, entry): Don't declare as being globally dynbound.
(org-agenda-format-date-aligned): Remove unused var `weekyear`.
(org-agenda-mode): `run-mode-hooks` is always available nowadays.

* testing/lisp/test-org-attach.el:
* testing/lisp/test-org-agenda.el:

* lisp/org-macs.el (org-eval-in-environment): Declare obsolete.
(org-dlet, org-pushnew-to-end): New macros.
