Packed structures cannot be passed by reference, may fail on
alignment-strict architectures, and are bad for performance even on
alignment-tolerant architectures. Using them for anything other than an
abstract layout declaration is a mistake. Remove
__attribute__((packed)).
gcc-5 rejects `constexpr bool DefiningMarkerMessage() const` because
`d_marker_state` is not literal. Later versions of gcc accept this, but
the `constexpr` is not useful here since one term is a runtime variable.
Remove `constexpr`.
Also, modify the definition of `marker_message_text_t` and
`d_marker_state` to encourage the compiler to initialize `MarkerState`
at compile time instead of load time.

User roncli reports[1] an original game bug that prevents boss
teleportation from operating correctly if the program is not restarted
between each campaign. This is another case of a global variable being
used improperly. Reset the relevant variables when the boss is
initialized.

If !defined(DXX_HAVE_CXX_BUILTIN_FILE_LINE), the default value is
omitted, but the comma between values is still required. The comma was
incorrectly guarded, so it was present only when a default value was
set.

Fixes: 544fc0f893 ("Add support for increased precision of gamelog timestamps")
- Enable display of subsecond (Linux: microseconds; Windows:
milliseconds) precision on gamelog timestamps.
- Add disabled support for YYYY-MM-DD leaders on gamelog timestamps.
Activate it by defining DXX_CONSOLE_TIME_FORMAT_YMD to true.
- Add disabled support for capturing caller __FILE__, __LINE__ in calls
to con_printf, con_puts. Activate it by defining
DXX_CONSOLE_SHOW_FILE_LINE to true. If captured, write those to
gamelog after the timestamp and before the text. This feature (and
only this feature) requires that DXX_HAVE_CXX_BUILTIN_FILE_LINE be
defined, which is conditional on if the compiler has __builtin_FILE()
and __builtin_LINE(). If the compiler lacks this support, attempts to
enable this feature are ignored.
- Switch to using GetLocalTime on Windows.
This code was part of a feature abandoned before retail. It cannot be
usefully used in campaigns. Remove it to reduce code size and simplify
later changes.
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.
d2x::segment has all members of d1x::segment, as well as two new members
exclusive to d2x::segment. Structure layout is such that d1x::segment
requires the same size allocation, and places anonymous pad members in
the locations that become named members in d2x::segment. Thus, reusing
d2x::segment for d1x::segment does not change the size of the structure
nor the offsets of any members used. This reuse may enable some
functions to be better shared by the dsx project.
`value` is generic and unclear. It is always meant to be used as an
index into the Station array, so rename it `station_idx` to show this.
Define and consistently use `station_none` to represent that no station
is assigned.
Using precompiled headers includes vers_id.h into
similar/main/newdemo.cpp. gcc-4.9 reports a conflict between vers_id.h
`extern const char g_descent_build_datetime[21]` and newdemo.cpp macro
generated `extern const char g_descent_build_datetime[]`. The size is
only needed in the definition, so remove it from the declaration to
align with the macro-generated extern.
Delete stub "compiler-type_traits.h" header. Redirect all uses to the
standard <type_traits> header.

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.
Early unification efforts missed this one because it was in gamemine.c
for Descent 1, but segment.c for Descent 2. Move it to gamemine.cpp for
both, so that it can be static for both games.
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:

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.
Hat labels reserve an extra character for the arrow, which partially
masked this error. When used buttons requires more characters than (1
+ used hats), the buffer had insufficient space and the label was
truncated.
x86_64-w64-mingw32-g++ -Wformat handling misparses the std::size_t
format string, causing a spurious error.
common/main/valptridx.tcc: In function 'void untyped_index_mismatch_exception::prepare_report(const char*, unsigned int, const void*, long int, const void*, const void*, char (&)[229], std::size_t)':
common/main/valptridx.tcc:36:182: error: format '%u' expects argument of type 'unsigned int', but argument 7 has type 'std::size_t {aka long long unsigned int}' [-Werror=format=]
This occurs even though the processed text uses %I64u (which is correct
for a `long long unsigned int`), not %u as shown in the error message.
static void prepare_report(const char *const filename, const unsigned lineno, const void *const array_base, const long supplied_index, const void *const expected_pointer, const void *const actual_pointer, char (&buf)[report_buffer_size], const std::size_t array_size)
{
snprintf(buf, sizeof(buf), "%s:%u: " "pointer/index mismatch:" " base=%p size=%" "I64u" " index=%li expected=%p actual=%p", filename, lineno, array_base, array_size, supplied_index, expected_pointer, actual_pointer);
}
In practice, all such sizes will fit in `unsigned int` because they are
the dimension of an array of large structures. Switch all platforms to
use `unsigned long`, which works everywhere and is at least as big as
`unsigned int`. Using `unsigned long` produces the same size as
`std::size_t` on all platforms other than Win64, where `unsigned long`
is only 32 bits due to the strange LLP64 model Microsoft picked.
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.
