zicodxx reported in issue #449 that savegames created in a new build,
then loaded in an older one, may behave incorrectly in the old build.
This cannot be fixed in the new build without reverting the logic change
which caused it. Support for old builds has always been best effort, so
this will not be fixed. Add a release note about it.

The minimum supported compiler versions now provide a depth-efficient
implementation of std::make_index_sequence, which removes the last
reason to carry a private implementation. In the case of clang, it
appears to have a special compiler intrinsic used to implement its
std::make_index_sequence.
Switch to the compiler-provided version for both gcc and clang.
The new Raspberry Pi 4B revision has a minimum requirement of Raspbian
buster, and uses the Mesa V3D driver by default; in fact, the legacy
Broadcom drivers are no longer compatible with its VideoCore VC6 chip, so
building against Mesa is mandatory for this Pi revision.
Unfortunately, the Debian buster version of the Mesa packages
have intentionally dropped the GLESv1 headers, making building of GLESv1
software impractical (even though the VC4/V3D driver can still run GLESv1
applications).
The OpenGL driver in conjunction with SDL2* runs at full
speed on Raspberry Pi 3B & 4B, so it makes sense to modify the "mesa"
build to this configuration in light of these facts.
* SDL2 is highly desirable due to the availability of the KMSDRM driver, which is
the only way to run dxx-rebirth outside of X (we can no longer use
the dispmanx/rpi driver of SDL1).
Commit e6169f17f9 switched from searching `Data/` to searching
`data/`. For users on case-insensitive filesystems, this is a no-op and
the instructions that reference the `Data` directory continue to work.
For users on case-sensitive filesystems, the change broke accessing the
data directory, and caused the instructions to mislead. Given the age
of the commit, fixing the capitalization now will likely cause more
problems than it solves. Instead, fix the capitalization of the
instructions, so that users who follow the documentation get a working
setup.

Commit dc79bb8e4a intended to clean up processing guidebot messages,
but accidentally allowed the guidebot to report certain status messages
before its cage was opened. Normal missions still do not report these
messages, but some custom levels do.

Fixes: dc79bb8e4a ("Remove hack for bypassing buddy time restriction")
This was requested by a user in early 2018. However, the proposed
prototype was susceptible to various forms of desynchronization, and was
unsuitable for merging. No further revisions were proposed, and the
feature languished. This commit enables the guidebot in cooperative
games and addresses the known synchronization problems, as well as some
other bugs that were uncovered during light testing. This is classified
as an experimental feature because it has not been heavily tested in
complicated games.

Remove use of object_guidebot_cannot_reach and instead track the
reachability of the object as a separate flag. This allows the game to
remember when an object was found, but unreachable. Previously, it
would store only that some unreachable object was found. Now, it stores
the index of the unreachable object. This extra information is not used
yet.

Fixes: c3cead4319 ("Move Escort_goal_index to d_unique_buddy_state")
Utility xrange, inspired by the Python2 feature of the same name,
provides an object that returns successive values from [start, end). It
is useful when the end index is known in advance, and is particularly
helpful when that index is expensive to recompute.
Fix original bug that buddy was limited to 5 hints per program run, not
5 per boss as it probably should have been.
Due to savegame format limitations, this still is not right. Reloading
the game should restore Buddy_gave_hint_count to its value at save time,
but will not.
When exactly four bytes remain, mvelib will attempt to compute a
past-the-end pointer. Some handlers will dereference this pointer
without rechecking the length. Adjust the header check to require a
non-empty body.

- Raise the player limit to 8.
- Remove the logic that forces player counts up/down when switching
between cooperative and deathmatch game modes.
- Add heuristics to add start positions for the extra players, since
standard maps will not have the required number of starts.
`check_effect_blowup` should receive the `laser_info` of the weapon that
caused the blast. Previously, it was given the `laser_info` of the
parent of that weapon. The parent was not of type `OBJ_WEAPON`, so
passing its `laser_info` is meaningless.

Add experimental support for using ADL MIDI instead of SDL for music
playback. Support for ADL MIDI contributed by Github user jpcima. This
feature is minimally supported by the core Rebirth team, but is included
as a courtesy so that users need not patch in support separately.
Suggested-by: jpcima <https://github.com/dxx-rebirth/dxx-rebirth/pull/408>
Add configuration file entries for number of chips, bank index, and
whether to use ADL MIDI. Currently, there is no GUI for this.
Interested users must enable it via direct configuration file editing.
A menu interface will come later.
The movie code assumes that when the topmost window is closed, that
window must have been the movie window, and that the movie data can now
be freed. However, if the movie is paused, a new topmost window is
created to tell the user that the movie is paused. When that topmost
pause window is deleted, the movie code frees the movie data, even
though the movie is not done. Corruption ensues, ultimately leading to
a crash.

Add macro cf_assert ("control flow" assert) to hint to gcc that certain

Commit 07245a0bc2 added the SDL_mixer backend for MVE audio. That
commit set the length of the converted sound equal to the size of the
buffer that SDL requested as a work area. No one ever touched that
logic, until now. In SDL1, that choice worked fine. In SDL2, this
causes garbage to play after the sound, because SDL2 considers the
buffer to be defined only up to the length returned in
`SDL_AudioCVT::cvt_len`. Bytes beyond that length are undefined[1], and
in practice contain garbage. Fix the noise by setting the sound length
equal to the length returned by SDL2, so that the undefined bytes are
not treated as sound. SDL1 also maintains this length value, so no
version-specific logic is required.

This script was written years ago and has sat unused since then.
Recently, someone asked for a copy, so I may as well publish it. The
HXM support may not have been tested, but the base HAM support can
successfully deconstruct Vertigo and reassemble a bit-wise identical
copy.
clang issues -Wformat-nonliteral when `vsnprintf` is passed the format
string from its caller. This is generally not useful. Fortunately, the
warning can be suppressed by annotating the function as format(printf).
Presumably, this is because clang now trusts that the caller would have
been warned for a bad format string.

psyke83 reports that Debian distributions for Raspberry Pi now require a
different name for some video libraries. Merge psyke83's SCons
enhancements to add support for the new names while retaining support
for the old names.
Vendor library has new names to avoid conflicts with Mesa. Update
raspberrypi argument to use new libraries and support Mesa VC4 driver.
* raspberrypi=1 will build against the (newly named) vendor libraries
* raspberrypi=mesa will target building against the VC4 driver.
Both will select GLES by default, but you can target GL for the VC4 driver
via "raspberrypi=mesa opengles=0"

Commit f4b21088a0 ("Track vulcan ammo explicitly") fixed an original
retail bug that prevented the thief from stealing energy weapons,
because the thief could only steal weapons for which the player had ammo
and energy weapons never have ammo. This went unremarked for several
years, until a recent report of the new semantics as a game-breaking
regression because the thief is now "ridiculously potent".
Address this report, as well as an intermittently raised issue from
various users over time, by adding two new knobs to both the single
player "Gameplay" menu and the multiplayer setup screen: "Remove Thief
at level start" and "Prevent Thief Stealing Energy Weapons".
"Remove Thief" deletes the thief object during level load. It has no
impact on save games, and changing it after entering a level has no
effect on any thief already in the level.
"Prevent Thief Stealing" is checked at the moment of theft and, when
enabled, prevents stealing primary weapons other than Vulcan/Gauss.
This can be changed at will in single player and is immediately
effective. In multiplayer, this option can only be changed by the game
host in the pre-game setup.
For both knobs, there is one pair of checkboxes to control this as a
player preference, which applies in single player games. There is a
second pair of checkboxes in the multiplayer setup, which applies only
to multiplayer games. Therefore, in multiplayer, the host chooses thief
settings and all clients use the host's choice. The host may configure
the thief differently in multiplayer from how the host plays in single
player.
For users who wanted to remove the thief, no specific tally has been
kept for who requested it or when. Now that the code is being updated,
this is thrown in as an easy addition.
