Fix issue in clang where args were inverted last to first due to the way
c++ implements function calls.
The function make_tuple, being a function, has undefined ordering of
resolution of the values of its parameters `Ps(init)` and would vary
between compilers. Namely clang would resolve them in order and msvc
would resolve them in reverse order.
This normally would not matter except for the fact that init maintains
a mutable state which is affected my the order of operations:
init.ordinal is a counter and also defines where in memory a value is
stored.
The C++ standard doesn't define an order of resolution of parameters in
a function but it will define an order in a brace-initializer.
Switching make_tuple for a brace-initializer enforces an order which is
the same between all compilers (tested gcc, clang and msvc).
Prior code was written to decrement ordinal due to the reverse
traversal.
This has been switched to incrementing thanks to the in-order
traversal.
shm_unlink(name) is the proper way to close a shared memory in linux.
Prior to this, xenia was creating and not cleaning up shared memory handle
which would accumulate in /dev/shm. shm_unlink is the proper way of doing
this.
Add filename to CloseFileMappingHandle signature.
Add simple test to open and close.
CreateFileMappingHandle now takes shared memory name without a prefix.
The doc of shm_open recommends not using slashes and prefixing with "/".
The prefixing has been moved to the os implementation layer.
Invocations of CreateFileMappingHandle were all using "Local\\" so these
prefixes were removed.
Document research about viz queries.
v2: Remove viz status unions and move comments to register definitions.
Add contributors to TODOs.
v3: Comment out unused variables.
Add TODO for correctly dropping draw calls with memexport.
Register comment formatting.
Add suspend count to thread implementation.
Increment suspend count on suspend and decrement on resume.
Wait on suspend count to be decremented to 0.
Return suspend count on suspend and on resume before incr/decr.
Fix naming of resume suspend count to make clear that suspend count is
before incr/decr.
Add test.
