Fix some crashes on self-modifying Elisp code
Prompted by a problem report by Alex in:
http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00143.html
* src/eval.c (For, Fprogn, Fsetq, FletX, eval_sub):
Compute XCDR (x) near XCAR (x); although this doesn't fix any bugs,
it is likely to run a bit faster with typical hardware caches.
(Fif): Use Fcdr instead of XCDR, to avoid crashing on
self-modifying S-expressions.
(Fsetq, Flet, eval_sub): Count the number of arguments as we go
instead of trusting an Flength prepass, to avoid problems when the
code is self-modifying.
(Fquote, Ffunction, Fdefvar, Fdefconst): Prefer !NILP to CONSP
where either will do. This is mostly to document the fact that
the value must be a proper list. It's also a tiny bit faster on
typical machines nowadays.
(Fdefconst, FletX): Prefer XCAR+XCDR to Fcar+Fcdr when either will do.
(eval_sub): Check that the args are a list as opposed to some
other object that has a length. This prevents e.g. (if . "string")
from making Emacs dump core in some cases.
* test/src/eval-tests.el (eval-tests--if-dot-string)
(eval-tests--let-with-circular-defs, eval-tests--mutating-cond):
New tests.

; Fix previous commit
The mailcap minibuffer completion used dynamic binding. Locally set
a dynamic variable.
* lisp/dired-aux.el: Store list of files in
`minibuffer-completion-table'.

dired-delete-file: Do not TAB complete the user answer
This action might delete directories containing valuable information.
Before previous commit, we prompted users with `yes-or-no-p'
which doesn't TAB complete the user answer. Let's play safe and
keep requiring full answers.
* emacs-master/lisp/dired.el (dired-delete-file): Use `read-string'
instead of `completing-read' to read the user answers.

dired-do-delete: Allow to delete dirs recursively without prompts
* lisp/dired.el (dired-delete-file): Accept 2 additional answers:
'all', to delete all directories recursively and no prompt anymore.
'quit', to cancel directory deletions (Bug#27940).
Show help message when user inputs 'help'.
(dired-do-flagged-delete): Bind locally dired-recursive-deletes
so that we can overwrite its global value.
Wrapp the loop within a catch '--delete-cancel to catch when
the user abort the directtry deletion.
* doc/emacs/dired.texi (Dired Deletion): Update manual.
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 26.1):
Announce this change.

Fix a couple of make-temp-file races
* lisp/emacs-lisp/autoload.el (autoload--save-buffer):
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
Use make-temp-file, not make-temp-name, to avoid an unlikely race
that could lose data. Remove the deletion hook as quickly as
possible after the file is renamed; though a race still remains
here, it is smaller than before.

dired-revert: save line numbers instead of positions
Positions might change if the length of one dired header line
changes; this happen, for instance, if we add new files.
Instead, line numbers are invariant under shrinks/enlargements
of the file header.
https://lists.gnu.org/archive/html/emacs-devel/2017-07/msg01092.html
* lisp/dired.el (dired-save-positions): Save the line numbers at point.
(dired-restore-positions): Use forward-line to restore the original
position (Bug#27968).
* test/lisp/dired-tests.el (dired-test-bug27968): Add test.

Fix a bug in 'generate-new-buffer-name'
