We were using a second std::vector as a buffer to convert another
std::vector's data into a byte sequence, however we can just use
pointers to the original data and use them directly with WriteBuffer,
which avoids copying the data at all into a separate std::vector.

We simply cast the pointers to u8* (which is allowed by the standard,
given std::uint8_t is an alias for unsigned char on platforms that we
support).

Prevents implicit conversions.

Gets rid of relying on indirect inclusions.

Previously we were just copying the data whole-sale, even if the length
was less than the total data size. This effectively makes the
actual_data vector useless, which is likely not intended.

Instead, amend this to only copy the given length amount of data.

At the same time, we can avoid zeroing out the data before using it by
passing iterators to the constructor instead of a size.

game_list: Make ContainsAllWords an internally linked non-member function

* Virtual Filesystem

* Fix delete bug and documentate

* Review fixes + other stuff

* Fix puyo regression

This was introduced within 4f81bc4e, and
considering there's no comment indicating that this is intentional, this
is very likely a bug.

Without these, this would perform concatenation, which is definitely not
what we want here.

Avoids pointless copies

This makes it a compilation error to construct additional instances of
the System class directly, preventing accidental wasteful constructions
over and over.

This would result in a lot of allocations and related object
construction, just to toss it all away immediately after the call.

These are definitely not intentional, and it was intended that all of
these should have been accessing the static function GetInstance()
through the name itself, not constructed instances.

Previously, we were on 4.1.0, which was a major version behind.

Previously this wouldn't compile, since no such function named
SaveStructDebugInfo() exists.

Touchscreen Support

This function actually depends on no internal class state, so it doesn't
even need to be a part of the class interface.

 game_list: Make containsAllWords a const member function 

Telemetry: Minor changes

game_list: Remove unnecessary QString initialization in KeyReleaseEater

astc: Minor changes

We can just take the value parameter by value which allows both moving
into it, and copies at the same time, depending on the calling code.

These operators don't modify internal class state, so they can be made
const member functions. While we're at it, drop the unnecessary inline
keywords. Member functions that are defined in the class declaration are
already inline by default.

Implement buffer cropping and default to handheld mode

This provides the equivalent behavior, but without as much boilerplate.
While we're at it, explicitly default the move constructor, since we
have a move-assignment operator defined.
