There's no need to use the "A" version of GetModuleFileName on GDK; it returns
a UTF-8 string directly on this platform, but we can still use the UTF-16 "W"
version and cut down on code duplication.
This code runs once and caches the results, so we can take the one-time string
conversion overhead.
(cherry picked from commit 6b780c5ff9)
core/unix had a more-limited copy of filesystem/unix's implementation, called
SDL_GetExeName(). Replace that with a real implementation in filesystem, and
allow each platform to implement it as appropriate.
Implemented for Unix and Windows; most implementations are currently FIXME
stubs at the moment.
Reference Issue #15692.
(cherry picked from commit 7d29ce8e31)
Now apps can have persistent files available during SDL_main()/SDL_AppInit()
and don't have to mess with Emscripten-specific code to prepare the filesystem
for use.

It SDL_SYS_EnumerateDirectory was changing the path string and passing it to
the callback, causing chaos in the glob handler, which expected the original
string to pass through.
Fixes#15057.
(cherry picked from commit a3b0403412)
Full paths are used as-is, relative paths are prepended with SDL_GetAndroidInternalStoragePath(), and operations fall back to the asset system as appropriate.
This is consistent with the behavior of opening files on Android.
...so the backends don't have to do it.
Also added a stern warning about `org` being omitted, but leaving it as
allowed so as not to break existing apps (more than they are already broken,
at least).
Fixes#13322.
This specifically affects SDL_EnumerateDirectory and SDL_GetPathInfo. Android
assets are read-only, so no need to do this for things like
SDL_CreateDirectory, etc, and the POSIX SDL_CopyFile() uses SDL_IOStream
behind the scenes, which already supports Android assets.
Fixes#13050.
The surrounding code in all of these instances expects the Unicode
variants. Previously, this code mixed Unicode and ANSI/ASCII calls if
`UNICODE` was undefined, which caused type and logic errors. Explicitly
spelling out the W removes any reliance on that macro.
Note that SDL_FlushIO() doesn't make promises about file data sync but that
is intended to be changed in the IOStream code in a later commit.
Fixes#10886.
