This allows us to set an explicit stack size (overriding the system default
and the global hint an app might have set), and remove all the macro salsa
for dealing with _beginthreadex and such, as internal threads always set those
to NULL anyhow.
I've taken some guesses on reasonable (and tiny!) stack sizes for our
internal threads, but some of these might turn out to be too small in
practice and need an increase. Most of them are simple functions, though.
We now only raise the magic exception that names the thread when
IsDebuggerPresent() returns true. In such a case, Visual Studio will
catch the exception, set the thread name, and let the debugged process
continue normally. If the debugger isn't running, we don't raise an exception
at all.
Setting the name is a debugger trick; if the debugger isn't running, the name
won't be set if attached later in any case, so this doesn't lose functionality.
This lets this code work without assembly code, on win32 and win64, and
across various compilers.
The only "gotcha" is that if you have something attached that looks like a
debugger but doesn't respect this magic exception trick, the process will
likely crash, but that's probably a deficiency of the attached program.
Fixes Bugzilla #2089.
WinRT 8.0 (Phone and non-Phone) didn't offer an API to set an already-created
thread's priority. WinRT 8.1 offered this API, along with several other
Win32 thread functions that were previously unavailable (in WinRT).
This change makes WinRT 8.1+ platforms use SDL's Win32 backend.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().
