Commit b1b5de4 switched from enabling select physics flags to setting
those flags and clearing all others. Unfortunately, flag PF_USES_THRUST
was omitted from the enabled list, so it was disabled on reset. It is
required to let player ships move.

Fixes: b1b5de4297 ("Additional safeguard for bug #306")
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.

Many of these locals are wasteful, since they are always sized to the
biggest buffer required. This is the minimal and safe solution. Future
work will tune them to the correct size.
(a+i) form assumes that a can be used as the left hand side of
operator+(). This is true for pointers, and for C arrays that degrade
into pointers, but not for C++ std::array. Switch to the explicit
syntax.

Little endian systems stored sound as a `uint32_t`, but sent only the
lowest byte. Store only that byte, since the destination was unaligned
and was the last field in the message.
All supported compilers have an acceptable <type_traits>. Commit
4cb3d46148 ("Move <type_traits> test to Cxx11RequiredFeature") made
<type_traits> support mandatory in August and no one has objected.
Remove the indirection and use namespace std directly for type_traits
members.
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const
Changes to common/include/valptridx.h and common/include/fwd-valptridx.h
are manual. All other changes are generated by:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\(v\?\)\(\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/\1m\2/g'
for the 'm' prefix and:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\([cm]\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/i&/g'
for the 'i' prefix.
For switch cases where existing comments or code flow logic obviously
intended to fall through, add a gcc-7 /*-fallthrough*/ comment to
silence warnings about this. Some cases which are less obvious are not
converted, so the code does not yet compile clean with
-Wimplicit-fallthrough.

Commit b32298df5a ("Rewrite powerup cap
code to centralize logic") centralized powerup cap code in the
powerup_cap_state class.
Commit 901a554e96 ("New powerup management
code: Addeed functions and packet type to ...") removed all use of
powerup_cap_state, but left the dead implementation present.
Commit 479f5ed584 ("Fix 'format specifies
type 'unsigned short' but the argument has type 'unsigned char''
warning") switched the already dead (but still compiled) code from %hu
to %hhu to fix a warning on OS X. Although the commit was written by
Chris, it was my suggestion to use %hhu. I neglected to test Windows
before suggesting it, so the change went in even though Windows does not
accept %hhu; this broke the Windows build. Fortunately, the code had
been dead for 11 months when the change was made, so the fix for Windows
is to remove the long dead code.
`get_weapon_id` must be called only on objects of type `OBJ_WEAPON`.
One path in `multi_compute_kill` could call `get_weapon_id` on an object
that is either a robot or a weapon. The code tested for a robot, but
only after performing an access that assumed it had a weapon. Reorder
the tests to prevent the type mismatch diagnostic.

By design, valptridx will throw an exception on invalid input. This is
better than silently permitting invalid input to corrupt program state.
Past releases blindly trusted that multiplayer peers would not send
invalid input. Conversion to the valptridx design eliminated the
undefined behavior when peers send invalid input, but still allowed
multiplayer peers to remotely crash the game by sending invalid inputs.
Add a mechanism to trap invalid inputs and gracefully ignore those
messages. This may cause game consistency issues, but will not allow
data corruption.
This is where a client in a multiplayer game hitting a wall fails an assert. Initialise obj->mtype.phys_info.flags in multi_reset_player_object() instead of adding flags. (Tested and still works OK without specifying PF_THRUST.)
Also happened when a client to a multiplayer game dropped out due to some network error. Delay call of multi_leave_game() until responding to EVENT_WINDOW_CLOSE, so the game isn't in an unstable state between handling the network event and the game closing.
In multi_do_frame(), replace call to window_close(Game_wind) with returning window_event_result::close whenever multi_quit_game is true. Only using this return value where multi_do_frame() is directly called by GameProcessFrame(). multi_quit_game will only be set back to 0 when a new multi game is started.
Closing a window within its handler is problematic - it can result in an unstable state.
Replace call to window_close(Game_wind) with returning window_event_result::close to game_handler. Applies to when there is a failure in net_udp_level_sync(). Closing a window within its handler is problematic - it can result in an unstable state.
`struct object_rw` is poisoned prior to initializing and sending it.
However, some fields are legitimately unininitialized (other than their
memset or poison value) at send time. Add and use a poison variant that
can clear those fields, without marking them unreadable.
When the reactor is forcibly destroyed by the kill goal code, print to
the console and the game log the data that players could otherwise
capture with a screenshot of the network player information.
zicodxx reported an assertion failure when powerup duplication was
enabled. Local debugging shows that some levels give preplaced powerups
a movement type of MT_NONE rather than MT_PHYSICS. Such powerups have
undefined data in their mtype.phys_info branch, which confuses the
physics simulation code. Powerups only need MT_PHYSICS to bounce away
from their spawn site. Preplaced powerups never move.
Add assertions that preplaced powerups are MT_NONE. Change the
duplication call to create the duplicates with movement MT_NONE.
