Redefine as obsolete function alias for 'message'.
(bookmark-write-file): Use a progress reporter.
(bookmark-load-file): Use a progress reporter.
* lisp/progmodes/xref.el (xref-pop-to-location):
Rename from xref-pop-to-location. So that third-party
xref-show-definitions-function implementations can use it safely
(bug#36144). Update all callers.
* lisp/progmodes/xref.el (xref--transient-buffer-mode-map):
New variable.

This improves performance of base64-decode-region by about 7.5% on
my platform, and gets rid of some macros.
* src/fns.c (IS_ASCII, IS_BASE64, IS_BASE64_IGNORABLE)
(READ_QUADRUPLET_BYTE): Remove.
(base64_value_to_char, base64_char_to_value):
Now an array of two arrays. All uses changed.
(base64url_value_to_char, base64url_char_to_value):
Remove. All uses changed to the other array.
(base64_char_to_value): Entries are now of type signed char, not
short, since we can assume C99. Use C99 initializers; this is
clearer and caters to the (theoretical) possibility of systems
that do not use ASCII or do not have 8-bit bytes. Allow any index
in the range 0..UCHAR_MAX instead of limiting it to 0..127, so
that uses need not check for in-range indexes. Also record
padding chars. All uses changed.
(base64_decode_1): Always store number of chars in *NCHARS_RETURN,
for simplicity. All callers changed. Speed up the byte-fetching.
