It may make more sense to break this out into a separate file, as is
done for other options, but there's helper code present to regenerate
into the base PLIST itself, so I'm simply restoring to there for now.
This update fixes chat/ejabberd building.

Restore some PLIST content state from prior to the 23.2.4 update,
which mistakenly moved some hipe-related files that get built
universally to the PLIST.hipe list. The "--disable-hipe" option does
not impact everything. Build tested with the hipe option both enabled
and disabled. This should fix build breakages, e.g., NetBSD/aarch64.
(Separately, it's kind of unfortunate that this package uses both PLIST
variables and separate PLIST files to segment content driven by options.
It should really use one approach or the other consistently, but I
haven't touched that here.)

Since do-configure-pre-hook already depends on replace-interpreter, there
is no point in making any other stage depend on that as well. At best,
it has no effect. At worst it creates a hard-to-find difference between
builds that run "bmake install" directly and builds that split the build
into "bmake configure && bmake build && bmake install", as bulk builds
do.
This brings us up to the latest patch release for this branch before freeze...

OTP-16457 Application(s): diameter
The possibility of choosing a handler process for an
incoming Diameter request with a configured MFA was
documented in OTP 20.0, but counters (with
{traffic_counters, true}) were not incremented when
this process was on a remote node. Counters are now
incremented on the node that configures the transport
in question.
Introduced in OTP 21.3.
OTP-16459 Application(s): diameter
Transport options differing from those passed to
diameter:add_transport/2 were used in several
situations: when starting a transport process after
connect_timer expiry after an initial connection
attempt has failed, when starting a transport process
after a connection has been accepted, when sending
events, when returning options in
diameter:service_info/2, and possibly more. In
particular, the following configuration options to
diameter:add_transport/2 were dropped:
avp_dictionaries, incoming_maxlen, spawn_opt,
strict_mbit.
Moreover, any service options mistakenly passed to
diameter:add_transport/2 were interpreted as such,
instead of being ignored as the documentation states,
with the consequence that outgoing and incoming
requests saw different values of some options, some
were always taken from transport options, and others
from service options.
diameter:add_transport/2 must be called in new code for
the fix to have effect.
Introduced in OTP 20.1.

Highlights
==========
erts:
o The Kernel application's User's Guide now contains a Logger Cookbook
with common usage patterns.
o Numerous improvements in the new socket and net modules
Standard libraries:
o common_test: ct_property_test logging is improved
o ssl: Correct handling of unordered chains so that it works as expected
Tools:
o Emacs erlang-mode function that lets the user open the documentation for
an Erlang/OTP function in an Emacs buffer has been improved. Users will
be asked if they want the man pages downloaded if they are not present in
the system.
This release fixes one bug in erts.
--- Fixed Bugs and Malfunctions ---
OTP-16301 Application(s): erts
Related Id(s): ERL-1079
Large amounts of quickly executed dirty work could
cause heavy contention on an internal spin lock. The
spin lock was replaced by a mutex which behaves much
better under these conditions.
Potential Incompatibilities
Mnesia: Transactions with sticky locks could with async_asym transactions be committed in the wrong order, since asym transactions are spawned on the remote nodes. To fix this bug the communication protocol between mnesia nodes had to be updated, thus mnesia will no longer be able to connect to nodes earlier than mnesia-4.14 ,first realeased in OTP-19.0.
Stdlib: Debugging of time-outs in gen_statem has been improved. Starting a time-out is now logged in sys:log and sys:trace. Running time-outs are visible in server crash logs, and with sys:get_status. Due to this system events {start_timer, Action, State} and {insert_timout, Event, State} have been added, which may surprise tools that rely on the format of these events. New features: The EventContent of a running time-out can be updated with {TimeoutType, update, NewEventContent}. Running time-outs can be cancelled with {TimeoutType, cancel} which is more readable than using Time = infinity.{rel, Name, Vsn, RelApps, Opts}.
Highlights
Compiler:
erlc can now automatically use a compile server to avoid starting an Erlang system for each file to be compiled in a multi-file project. See the documentation for how to enable it.
Standard libraries:
SSL: Basic support for TLS 1.3 Client for experimental use. For more information see the Standards Compliance chapter of the User's Guide.
crypto: The Message Authentication Codes (MAC) CMAC, HMAC and Poly1305 are unified into common functions in the New Crypto API. See the manual for CRYPTO. cipher_info/1 functions returns maps with information about the hash or cipher in the argument.
In the previous version, pkglint would want to indent the continuation
line with a tab. To prevent this, the variable assignment is now printed
in its canonical format.
Just like humans, pkglint does not read the "do not edit" notice at the
top of the file. Maybe it should.
Erlang/OTP 22 is a new major release with new features and improvements as well as incompatibilities.
For a deeper dive into the hightligts of the OTP 22 release, you can read our blog here:
http://blog.erlang.org/OTP-22-Highlights/
Potential Incompatibilities
gen_* behaviours: If logging of the last N messages through sys:log/2,3 is active for the server, this log is included in the terminate report.
reltool: A new element, Opts, can now be included in a rel tuple in the reltool release specific configuration format: {rel, Name, Vsn, RelApps, Opts}.
All external pids/ports/refs created by erlang:list_to_pid and similar functions now compare equal to any other pid/port/ref with same number from that node.
The old legacy erl_interface library is deprecated as of OTP 22, and will be removed in OTP 23. This does not apply to the ei library.
VxWorks is deprecated as of OTP 22 and will be removed in OTP 23.
Erts:
Support for Erlang Distribution protocol to split the payload of large signals into several fragments.
ETS option write_concurrency now also effects and improves scalability of ordered_set tables.
The length/1 BIF used to calculate the length of the list in one go without yielding, even if the list was very long. Now it yields when called with long lists.
A new (still experimental) module socket is introduced. It is implemented as a NIF and the idea is that it shall be as "close as possible" to the OS level socket interface.
Added the NIF function enif_term_type, which helps avoid long sequences of enif_is_xyz by returning the type of the given term. This is especially helpful for NIFs that serialize terms, such as JSON encoders, where it can improve both performance and readability.
Compiler:
The compiler has been rewritten to internally use an intermediate representation based on Static Single Assignment (SSA). The new intermediate representation makes more optimizations possible.
The binary matching optimizations are now applicable in many more circumstances than before.
Type optimizations are now applied across local function calls, and will remove a lot more redundant type tests than before.
All compiler options that can be given in the source file can now be given in the option list on the command line for erlc.
In OTP 22, HiPE (the native code compiler) is not fully functional. The reasons for this are new BEAM instructions for binary matching that the HiPE native code compiler does not support. If erlc is invoked with the +native option, and if any of the new binary matching instructions are used, the compiler will issue a warning and produce a BEAM file without native code.
Standard libraries:
Cover now uses the counters module instead of ets for updating counters. The new function cover:local_only/0 allows running Cover in a restricted but faster local-only mode. The increase in speed will vary depending on the type of code being cover-compiled, as an example the compiler test suite runs more than twice as fast with the new Cover.
A simple socket API is provided through the socket module. This is a low level API that does *not* replace gen_[tcp|udp|sctp]. It is intended to *eventually* replace the inet driver. It also provides a basic API that facilitates the implementation of other protocols than TCP, UDP and SCTP. Known issues are; No support for the Windows OS (currently), a small term leakage. This feature will be classed as experimental in OTP 22.
SSL: now uses the new logger API, including log levels and verbose debug logging.
SSL: Basic support for TLS 1.3 Server for experimental use.
crypto: The new hash_info/1 and cipher_info/1 functions returns maps with information about the hash or cipher in the argument.
Highlights from erlang 21.2 to 21.3:
Kernel:
The standard logger handler, logger_std_h, now has a new internal
feature for log rotation. For full information see the documentation.
SSL:
The Reason part of the error return from the functions connect and
handshake has a better and documented format. This is a potential
incompatibility. See the documentation.
Refactoring of state handling has improved the TLS application data
throughput and reduced CPU overhead
Code optimizations has reduced CPU load for encryption/decryption,
especially for Erlang's distribution protocol over TLS
Now supports active N
Erl_interface:
Support for plugin of a user supplied socket implementation has been added.
OTP:
The HTML reference documentation now shows the OTP version where
modules and functions were first introduced. Versions of OTP older than R13B04 is not shown in the reference
documentation
