Do not rely on integer wraparound.

* xdisp.c (forward_to_next_line_start)
(back_to_previous_visible_line_start)
(reseat_at_next_visible_line_start, next_element_from_buffer):
Don't arbitrarily truncate the value of 'selective' to int.

not EMACS_UINT, for indexes.

(composition_gstring_p, composition_reseat_it)
(composition_adjust_point): Use EMACS_INT, not int.

(init_buffer_once): Check at compile-time, not run-time.

(struct sortstrlist.size, struct sortlist.used): Don't truncate size to int.

* window.el (same-window-p): Fix two typos introduced when
adding with-no-warnings.

Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
hosts with pre-C99 libraries, because pD is wrongly defined to "t".

* fileio.c (Finsert_file_contents):
* insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
Remove the old (too-loose) buffer overflow checks.
They weren't needed, since make_gap checks for buffer overflow.
* insdel.c (make_gap_larger): Catch buffer overflows that were missed.
The old code merely checked for Emacs fixnum overflow, and relied
on undefined (wraparound) behavior.  The new code avoids undefined
behavior, and also checks for ptrdiff_t and/or size_t overflow.

Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.

* window.el (enlarge-window, shrink-window): Don't report an error
when the window can't be resized as requested (Bug#8862).

(display-buffer): Don't check noninteractive when calling
display-buffer-pop-up-frame.
(display-buffer-pop-up-frame): Never pop up a frame in
noninteractive mode (Bug#8857).

(switch-to-buffer-same-frame, switch-to-buffer-other-window)
(switch-to-buffer-other-window-same-frame)
(switch-to-buffer-other-frame): Fix doc-strings.  Reported by Drew
Adams (Bug#8875).

* window.el (display-buffer-normalize-specifiers-1): Respect
current value of pop-up-frames for most reasonable values of
second argument of display-buffer (Bug#8865).

(insert_from_buffer_1, replace_range, replace_range_2):
* insdel.c (make_gap_larger):
* editfns.c (Finsert_char):
* fileio.c (Finsert_file_contents): Use it, to normalize wording.

auth-source.el (auth-source-save-secrets): New variable to control if secret tokens should be saved encrypted.
 (auth-source-netrc-parse, auth-source-netrc-search): Pass the file name to `auth-source-netrc-normalize'.
 (with-auth-source-epa-overrides): Add convenience macro.  Don't depend on the EPA variables being defined.
 (auth-source-epa-make-gpg-token): Convert text to a "gpg:" token.
 (auth-source-netrc-normalize): Convert "gpg:" tokens back to text in the lexical-let closure.
 (auth-source-netrc-create): Create "gpg:" tokens according to `auth-source-save-secrets'.

This is for the case where you want to force a `plain' network
connection, but the protocol still requires the capabilitiy command
(i.e., SMTP and EHLO).

(GET_CCL_RANGE, IN_INT_RANGE): Use it.
