Same behavior, but allows us to avoid a now-unnecessary zero
initialization.

The general pattern is to mark mutexes as mutable when it comes to
matters of constness, given the mutex acts as a transient member of a
data structure.

C++20 deprecates capturing the this pointer via the '=' capture.
Instead, we replace it or extend the capture specification.

We were performing an int < size_t comparison. We can just correct the
type of the induction variable.

I made a review comment about this in the PR that this was introduced
in (#3955, commit 71c47792), but it
seems to have been missed.

We shouldn't be using this pragma here because it's MSVC specific. This
causes warnings on other compilers.

The test it's surrounding is *extremely* dubious, but for the sake of
silencing warnings on other compilers, we can mark "placebo" as volatile
and be on with it.

file_sys/mode: Make use of DECLARE_ENUM_FLAG_OPERATORS with Mode

Allows some implementations to completely avoid unnecessarily zeroing
out the internal buffer.

More compact code.

Allows for more compact code.

Same behavior, minus a hand-rolled operator.

Top level const will always be ignored in this case, so it can be
removed.

While we're at it, we can avoid a redundant map lookup.

* ipc: Allow all trivially copyable objects to be passed directly into WriteBuffer

With the support of C++20, we can use concepts to deduce if a type is an STL container or not.

* More agressive concept for stl containers

* Add -fconcepts

* Move to common namespace

* Add Common::IsBaseOf

Oddly enough the scan that feeds the manual content provider is hardcoded to scan 2 nested directories deep.
This effectively rendered the scan subdirectories setting useless as the manual content provider cannot find any games located more than 2 nested directories deep.
Furthermore, this behavior causes game files to be picked up by the manual content provider even if scan subdirectories is disabled.

FIx this by utilizing the behavior described when populating the game list for populating the content provider.
