* lisp/erc/erc-backend.el (erc-process-sentinel): Clear channel user
lists upon disconnection.  This prevents invalid channel
user lists when reconnecting (bug#10947).

closed connection, this may already have been detected and
`erc-server-last-received-time' has been set to nil (bug#13608).

* lisp/erc/erc.el (erc-channel-receive-names): Fix errors
generated when multiple IRC clients talk to a single IRC proxy
(bug#19034).

(bug#18718).

Backport:

This is a work-around to prevent the compiler from using semantic
knowledge about malloc for optimization purposes.  E.g., gcc 5.2
with -O2 replaces most of calloc's definition by a call to calloc;
see Bug#22085.
* src/gmalloc.c [!HYBRID_MALLOC] (malloc, realloc, calloc)
(aligned_alloc, free): Do not undef.  Instead, define these as
functions (perhaps renamed to gmalloc etc.) in terms of gmalloc etc.

* lisp/net/browse-url.el (browse-url)
(browse-url-default-browser, browse-url-default-windows-browser)

(browse-url-kde, browse-url-text-xterm): Clarify the usage of ARGS
and NEW-WINDOW arguments in these functions.  (Bug#19421)

* src/eval.c (unbind_to): Redo so that the FALLTHROUGH!! comment
becomes accurate again. This shouldn’t affect behavior.

avoid producing non-ASCII characters in the *scratch* buffer's
commentary.

empty path into an absolute ("/") path.

reference URI should not drop the last segment.
