Additionally, this resolves the remaining GPLv2 only licensed files by relicensing them to GPLv2.0-or-later.

Guest logs are not very useful, as they are intended for use by the game developers during development. As such, they provide little meaning to be logged by yuzu and tend to overwhelm the log output at times.

Transition to PascalCase for result names.

Avoids unnecessary default construction of an entry in cases where no
entry exists before overwriting the created entry.

We can perform the lookup and then do the contains check by checking the
end iterator. The benefit of this is that if we *do* find an entry, then
we aren't hashing into the map again to find it.

We can also get rid of an unused std::vector temporary while we're at
it.

Resolves a trivial warning with clang.

Fixes assertion on Bloodstained Ritual of the Night.

We would over read sometimes, this is fixed by checking if the top bit is set in the first iteration. We also lock the loop off to be only the max size of the type we can fit. Finally we changed an incorrect print of "DEBUG" to "TRACE" to reflect the proper log severity
