Cleanup code style.
Move ActionReplay code->INI saving into ActionReplay namespace.
Threadsafety Cleanup: ActionReplay is accessed from the Host, Emu
and CPU Threads so the internal storage needs to be protected by a
lock to prevent vectors/strings being deleted/moved while in use by
the CPU Thread.
UI Consistency: Make ARCodes behave like Gecko Codes - only apply
changes when Apply is pressed. Save changes to INI from CheatsWindow.
ISOProperties/CheatsWindow now synchronize with each other.
ISOProperties loads codes using ActionReplay::LoadCodes which actually applies
the codes to the global state. If a game is running then that games receives
all the codes (and ACTIVE status) from the second game being shown in
ISOProperties which is not desirable.
Donkey Kong Country Returns is writing new data to some files in /tmp
when loading each level. But the savestate code was opening the files
a second time and reading some old and stale data out.
As of #3798, dolphin now correctly restores that stale data to /tmp,
which broke DKCR (and probally countless other games).
This PR closes all file handles before saving and loading savestates,
which flushes the data out and pervents this issue. (old savestates
are corrupted and will still cause crashes if loaded)
On master, when polling the 1st in-game controller, Dolphin would poll all the 1st local controllers. With the 1st commit, each client waits its turn, which would dramatically increase the lag.
Now with this commit, it even polls all local controllers at once, so it should have even less latency than master in a few setups. Like one player with 3 controllers and the 2nd one with just one controller.
This fixes issues with setups like:
Player 1 uses port 1 and player 2 uses port 3, or
player 1 uses port 2 and player 2 uses port 3, so nobody uses port 1
Also swaps the byte order from RGBA->BGRA to match GL/D3D12, and what
the read handler is expecting.
Depth reads will now return the minimum depth of all samples, instead of
the average of all samples.
Using glMapBufferRange to read back the contents of the SSBO is extremely
slow on NVIDIA drivers. This is more noticeable at higher internal
resolutions. Using glGetBufferSubData instead does not seem to exhibit
this slowdown.
