splitpath_t is designed for MS-DOS paths, even though Rebirth now runs
on many platforms that never used DOS conventions. Most of the members
of splitpath_t are unused on all platforms. Remove them, and switch to
returning an initialized version of the structure.
Players are not robots, but the show-path cheat tried to pretend they
are, and triggered a BUG warning[1] when looking up robot information
from the player object. Fix this by passing in the robot_info when the
caller is providing a robot, and a named `nullptr` value (as
`create_path_unused_robot_info`) when the caller is providing a
non-robot object.

similar/main/ai.cpp:1905: BUG: object 0x555555858550 has type 4, expected 2

```
attempt_to_steal_item_3 always fails if the thief is not in
AIM_THIEF_ATTACK mode. The caller will call attempt_to_steal_item_3
repeatedly in some cases, but the mode does not change during the calls,
so if one fails for this reason, then all will fail for this reason.
Lift the check into the caller so that the loop of repeated calls can be
skipped if the mode check fails.
Use `object &` instead of `vmobjptr_t`. This should generate equivalent
code, but produce smaller debug information and may require less
inlining by the compiler.
If exactly one object will always be needed, use an overload that
returns the object id. Otherwise, use an overload that only returns
whether at least one object was created. This simplifies callers that
always request exactly one object.
This variable is only used in a print statement which is itself
commented out. Move the declaration, assignment, and commented print
into a preprocessor guard.
Iterating over it returns each side number in turn. This allows
converting many loops of the form:
```
for (int i = 0; i < MAX_SIDES_PER_SEGMENT; ++i)
```
to the compact form:
```
for (const auto i : MAX_SIDES_PER_SEGMENT)
```
The compact form brings the usual benefit of range-based for: delegating
iteration to the compiler prevents the loop body from skipping a step,
and makes clear in the code that this is the case.
Previously, the guidebot menu was given the full screen dimensions and
drew on only part of them, allowing the rest of the screen to be visible
due to not repainting it. Change to make the escort_menu window the
size that the user sees.
Commit d0d7545ec1 ("Unload robot movies on exit") intended to shorten
the lifetime of the loaded data, but failed to save the unique_ptr, so
the lifetime was shortened more than intended. Save the unique_ptr so
that the movies remain loaded.
Also, add a [[nodiscard]] annotation so that the compiler can warn if
this mistake is repeated.

Some callers will need access to the computed path. Change the callers
to pass in a buffer for this path, and have PHYSFSX_addRelToSearchPath
fill that buffer directly.
Commit 479884288c unintentionally caused the movie window to linger in
the background after a movie was played, which causes a crash when the
window is used later, because part of its state has been cleared.
Use window::track to detect its termination in the usual way, and
eliminate the special logic that tried to track the window by deferring
its deletion. This causes the window to close at the proper time,
thereby avoiding a later crash.
Fixes: 479884288c ("Always delegate to window_create for send_creation_events")
Callers only ever test for whether the movie was skipped, and never
distinguish between a movie that ran to completion versus a movie that
the user interrupted. Combine these two statuses into one value, and
eliminate the logic in RunMovie that picked which of the two to return.
It existed to support the freestanding mve player, which has not been
maintained in years. Even there, the support can be retained by
aligning the name of the function among the source files. mve_main.c
would need to be converted to C++ to enable full support.
