Descent 1 mangles colors during `g3_init_polygon_model`, so this must
not be called on polygons not designed for mangling. Rearrange the
logic to allow Descent 1 to verify that polygon models are well-formed
without using the functions that mangle the colors.

Windows std::ptrdiff_t is `int` instead of `long` as it should be.
Expand the values out to `long` (which is the same size as `int` on
Win32!) before printing them. This fixes format string warnings.

The highest-level tracking code assumed filenames would always fit in a
char[9]. This was true on DOS, but has not been true in Rebirth for
many years. Builds without fortification caused silent memory
corruption in this case.
Refuse to create highest-level entries if they would cause corruption.
Log a diagnostic telling the user that this happened.
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.
Bitmaps based on grs_main_bitmap own their data. Bitmaps based on
grs_bitmap do not. Adjust prototypes to prevent initializing a
grs_main_bitmap with data it will not own.
Release builds should never have an object in CT_SLEW state. If they
do, they abort the program. This is an extreme reaction. Change the
logic to report the problem, then coerce the type to CT_NONE and try to
resume operation.
Processing sharepath in SConf is incorrect, because targets can share a
build directory (and therefore an SConf run), but not share a sharepath.
Move sharepath handling out of SConf. Move DXX_USE_SHAREPATH handling
from CGameArg to GameArg, since one game can be built with a sharepath
while the other is built without.
clang warns for using an uninitialized array during the
member-initialization-list, before the union constructor would have done
nothing. clang permits using the still-uninitialized array in the
constructor body, after the union constructor has done nothing.
The same code is generated both before and after this commit, but the
old code produces a warning and the new code is silent.
```
similar/main/physics.cpp:282:5: error: field 'a' is uninitialized when used here [-Werror,-Wuninitialized]
e(a.begin())

gcc-4.9 rejects defining a class with a reference member and no
constructor, even though the use of the class uses a
brace-initialization expression to set the reference at construction
time.
