There's nothing going on with behavior here that would prevent these
from being const qualified.
Also better communicates that this function isn't intended to modify the
given resource pack.
Mesa (llvmpipe) only reports 4x MSAA, and doesn't report 2x (or 1x, but we implicitly add that). The old logic did not handle this correctly, causing selecting 4x to fail and fall back to None.
This also removes VideoUtils::GetAvailableAntialiasingModes, and thus VideoUtils entirely, as its only other function was removed in 1f74653501fec1dd059705f8a3eff1edb259d4d9.
Before, Settings::SetDebugModeEnabled was used; this calls SetBaseOrCurrent() which will usually permanently change the base configuration setting for the debugger to true. Thus, the debugger would remain active even if the --debugger command line option was removed. Now, it remains active only for the current run, like other command-line options.
Note that SetBaseOrCurrent is also used by the "Show Debugging UI" option under Options -> Interface; this means that if the debugger is turned off (or off and then back on) by the user while --debugger is specified, this will be reset to whatever the base configuration had when Dolphin is closed and reopened. This behavior is consistent with the rest of the UI.
To my understanding, the --debugger option is something from 5.0 stable/DolphinWx where there was no way to toggle the debug UI in the settings (and the command-line option was the only way of enabling it). It's less useful nowadays.
This reverts commit fb265b610de08df5509e56beeb3dbff68f7d4396.
The optimization in that commit is safe when the executor thread is
writing and the GUI thread is reading, but I had failed to take into
account that it's unsafe when the GUI thread is writing and the executor
thread is reading. (The native UpdateAdditionalMetadata function loops
through m_cached_files, which is unsafe if another thread is adding
elements to m_cached_files simultaneously.)
Losing out on this optimization isn't too bad, because
719930bb390ed0020b99a7942289d83218e99d69 makes it very unlikely that
both threads will want the lock at the same time.
walking the zip prevents minizip from re-reading the same
data repeatedly from the actual backing filesystem.
also improves most usages of minizip to allow for >4GB,
files altho we probably don't need it
