When booting a Wii game, Dolphin can overwrite certain settings
in the SYSCONF file, such as turning off PAL60 for NTSC games.
Normally, these settings get reverted at the end of emulation, but
this does not happen if Dolphin crashes or force quits in some other
way. (Personally, I have a tendency to use Visual Studio's Stop
Debugging button, which kills the process...)
Dolphin also overwrites certain values in setting.txt when booting
a Wii game. Unlike with SYSCONF, we currently make no effort to
preserve the original values in this file.
This change fixes both of these problems by copying SYSCONF and
setting.txt to the Backup folder when booting a Wii game, and then
copying them back either when launching Dolphin (in case the
previous run of Dolphin crashed) or when ending emulation.
Previously the logging was a in a little bit of a disarray. Some things
were in namespaces, and other things were not.
Given this code will feature a bit of restructuring during the
transition over to fmt, this is a good time to unify it under a single
namespace and also remove functions and types from the global namespace.
Now, all functions and types are under the Common::Log namespace. The
only outliers being, of course, the preprocessor macros.
Continues the migration to using fmt.
Notably, this allows safely converting a map within USBUtils over to
containing string view instances, rather than std::string instances, as
fmt safely handles the formatting of string views.

This also includes another change: DolphinQt will now exit with an
error if you use --batch without specifying a game using any method
(unlike in the past where --batch would be ignored if you didn't
specify a game using --exec, even if you had used --nand-title).
The main reason why I did this was because coding the alternative
(ignoring --batch) would be annoying with render to main involved.
This feature was originally exclusive to the previous iteration of
DolphinQt (the one that was the reason for the current iteration
being named DolphinQt2 initially).

This new setting is like Override Language on NTSC Games, except
instead of only applying to the GameCube language setting,
it also applies to the Wii language setting.

This variable isn't std::moved anywhere and is just read out of into a
string. Instead of making a copy, and then another copy of the data into
a std::string, we can take it by reference, only copying the data once.
This isn't std::moved wholesale into a member variable or further
std::moved into another function, so it's better to take it by const
reference here to avoid unnecessary reallocations of contained
std::string instances.
Moves it closer to where its used, narrowing its visible scope, as well
as preventing unnecessary std::string constructor executions in the
event invalid data is encountered (the continue branch).
std::function is allowed to heap allocate in order to store captured
variables, etc, so std::function isn't a trivial type. We can std::move
here in order to avoid potential reallocating.
While we're at it, make the definition's parameter name match the
declaration's parameter name for consistency.
If the parameter is const, then a move won't actually be able to occur,
making the std::move non-functional. We can remove the const qualifier
to remedy this.
...in addition to the existing function CreateVolume
(renamed from CreateVolumeFromFilename).
Lets code easily add constraints such as not letting the user
select a WAD file when using the disc changing functionality.
Unfortunately, it appears that using libusb's synchronous transfer API
from several threads causes nasty race conditions in event handling and
can lead to deadlocks, despite the fact that libusb's synchronous API
is documented to be perfectly fine to use from several threads (only
the manual polling functionality is supposed to require special
precautions).
Since usbdk was the only real reason for using a single libusb context
and since usbdk (currently) has so many issues with Dolphin, I think
dropping support for it in order to fix other backends is acceptable.
Avoids dragging in IniFile, EXI device and SI device headers in this header which is
quite widely used throughout the codebase.
This also uncovered a few cases where indirect inclusions were being
relied upon, which this also fixes.
