Standardize auth-source queries in ERC
* lisp/erc/erc.el (erc-password): Deprecate variable only used by
`erc-select-read-args'. Server passwords are primarily used as
surrogates for other forms of authentication. Such use is common but
nonstandard and often discouraged in favor of the de facto standard,
SASL. Folks in the habit of invoking `erc(-tls)' interactively should
be encouraged to use auth-source instead.
(erc-select-read-args): Before this change, `erc-select-read-args'
offered to use the value of a non-nil `erc-password' as the :password
argument for `erc' and `erc-tls', referring to it as the "default"
password. And when `erc-prompt-for-password' was nil and
`erc-password' wasn't, the latter was passed along unconditionally.
This only further complicated an already confusing situation for new
users, who in most cases shouldn't be worried about sending a PASS
command at all. Until SASL arrives, they should provide server
passwords manually or learn to use auth-source.

network IDs over announced servers and dialed endpoints.

merging contextual and default parameters. This is another contender
for possible exporting.
(erc--auth-source-search): New function for consulting auth-source and

mentioned helpers.

value for auth-source query-function options.
(erc-server-join-channel): Use user option for consulting auth-source
facility. Also accept nil for first argument (instead of server).
(erc-cmd-JOIN): Use above-mentioned facilities when joining new
channel. Omit server when calling `erc-server-join-channel'. Don't
filter target buffers twice. Don't call `switch-to-buffer', which

(erc-obsolete-var): Define new generic context rewriter.
(erc-networks-shrink-ids-and-buffer-names,

erc-networks--shrink-ids-and-buffer-names-any): Add functions to
reassess all network IDs and shrink them if necessary along with
affected buffer names. Also add function to rename buffers so that
their names are unique. Register these on all three of ERC's
kill-buffer hooks because an orphaned target buffer is enough to keep
its session alive.
(erc-networks-rename-surviving-target-buffer): Add new function that
renames a target buffer when it becomes the sole bearer of a name
based on a target that has become unique across all sessions and, in
most cases, all networks. IOW, remove the @NETWORK-ID suffix from the
last remaining channel or query buffer after its namesakes have all
been killed off. Register this function with ERC's target-related
kill-buffer hooks.
(erc-networks--examine-targets): Add new utility function that visits
all ERC buffers and runs callbacks when a buffer-name collision is
encountered.
(erc-networks--qualified-sep): Add constant to hold separator between
target and suffix.
(erc-networks--construct-target-buffer-name,

`erc-networks--reconcile-buffer-names' and friends.
(erc-networks--reconcile-buffer-names): Add new buffer-naming strategy
function and helper for `erc-generate-new-buffer-name' that only run
in target buffers.
(erc-determine-network, erc-networks--determine): Deprecate former and
partially replace with latter, which demotes RPL_ISUPPORT-derived
NETWORK name to fallback in favor of known `erc-networks-alist'
members as part of shift to network-based connection-identity policy.
Return sentinel on failure. Expect `erc-server-announced-name' to be
set, and signal when it's not.
(erc-networks--name-missing-sentinel): Value returned when new
function `erc-networks--determine' fails to find network name. The
rationale for not making this customizable is that the value signifies
the pathological case where a user of an uncommon IRC setup has not
yet set a mapping from announced- to network name. And the chances of
there being multiple unknown networks is low.
(erc-set-network-name, erc-networks--set-name): Deprecate former and
partially replace with latter. Ding with helpful message, and don't
set `erc-network' when network name is not found.
(erc-networks--ensure-announced): Add new fallback function to ensure
`erc-server-announced-name' is set. Register with post-MOTD hooks.

(erc-networks--insert-transplanted-content,
erc-networks--reclaim-orphaned-target-buffers,
erc-networks--copy-over-server-buffer-contents,
erc--update-server-identity): Add helpers for
`erc-networks--rename-server-buffer'. The first re-associates all
existing target buffers that ought to be owned by the new server
process. The second grabs buffer text from an old, dead server buffer
before killing it. It then inserts that text above everything in the
current, replacement server buffer. The other two massage the IDs of
related sessions, possibly renaming them as well. They may also
uniquify the current session's network ID.
(erc-networks--init-identity): Add new function to perform one-time
session-related setup. This could be combined with
`erc-set-network-name'.
(erc-networks--rename-server-buffer): Add new function to replace
`erc-unset-network-name' as default `erc-disconnected-hook' member;
renames server buffers once network is discovered; added to/removed
from `erc-after-connect' hook on `erc-networks' minor mode.
(erc-networks--bouncer-targets): Add constant to hold target symbols
of well known bouncer-configuration bots.
(erc-networks-on-MOTD-end): Add primary network-context handler to run
on 376/422 functions, just before logical connection is officially
established.
(erc-networks-enable, erc-networks-mode): Register main network-setup
handler with 376/422 hooks.

(erc-reuse-buffers): Make this an obsolete variable, but take pains to
ensure its pre-28.1 behavior is preserved. That is, undo the
regression involving unwanted automatic reassociation of channel
buffers during joins, which arrived in ERC 5.4 and effectively
inverted the meaning of this variable, when nil, for channel buffers,
all without accompanying documentation or announcement.
(erc-generate-new-buffer-name): Replace current policy of appending a
slash and the invocation host name. Favor instead temporary names for
server buffers and network-based uniquifying suffixes for channels and
query buffers. Fall back to the TCP host:port<n> convention when
necessary. Accept additional optional params after the others.
(erc-get-buffer-create): Don't generate a new name when reconnecting,
just return the same buffer. `erc-open' starts from a clean slate
anyway, so this just keeps things simple. Also add optional params.
(erc-open): Add new ID param to for a network identifier explicitly
passed to an entry-point command. This is stored in the `given' slot
of the `erc-network--id' object. Also initialize the latter in new
connections and otherwise copy it over. As part of the push to recast
erc-networks.el as an essential library, set `erc-network' explicitly,
when known, rather than via hooks.
(erc, erc-tls): Add new ID keyword parameter and pass it to
`erc-open'.
(erc-log-irc-protocol): Use `erc--network-id' instead of the function
`erc-network' to determine preferred peer name.
(erc-format-target-and/or-network): This is called frequently from
mode-line updates, so renaming buffers here is not ideal. Instead, do
so in `erc-networks--rename-server-buffer'.

(erc--current-buffer-joined-p): Add possibly temporary predicate for
detecting whether a buffer's target is a joined channel. The existing
means are inconsistent, as discussed in bug#48598. The mere fact that
they are disparate is unfriendly to new contributors. For example, in
the function `erc-autojoin-channels', the `process-status' of the
`erc-server-process' is used to detect whether a buffer needs joining.
That's fine in that specific situation, but it won't work elsewhere.

Update ISUPPORT handling in ERC
* lisp/erc/erc-backend (erc--isupport-params): Add new variable to
hold a hashmap of parsed `erc-server-parameters' in a more useful
format. But keep `erc-server-parameters' around for public use. We
currently lack dedicated local variables for certain discovered IRC
session properties, such as what prefix characters are supported for
channels, etc. And the truth of this needs querying many times per
second at various points. As such, caching here seems justified but
can be easily removed if deemed otherwise because all ingredients are
internal.
(erc--parse-isupport-value): Add helper function that parses an
ISUPPORT value and returns the component parts with backslash-x hex
escapes removed. This can probably use some streamlining.
(erc--with-memoization): Add compat alias for use in internal ISUPPORT

But there's no guarantee that the name will match the one ultimately
emitted by the server during its introductory burst. Beyond
potentially causing confusion in protocol logs, this behavior may
complicate debugging efforts. Setting the variable to nil helps
ensure a consistent environment when preparing a buffer for all newly
dialed connections. This commit also simplifies the setting of
`erc-server-connected', which is always nil when connecting and
