Update SDK

[komashchenko]

This fixes issues with CNetworkVar and adds support for CUtlHashMapLarge and MurmurHash3.

[Deathreus]

So much inline stuff, how'd you figure all this out

[psychonic]

What is the issue with CNetworkVar that this is fixing? And is the rest of the change necessary? This looks like a very large amount of code that was potentially not reverse engineered.

We're not interested in being a mirror for leaked code.

Closing this PR for multiple reasons

• File conflicts
• Author failed to mention the origin of the changes
• CSGO is no longer in active development. Not that it's a reason in on itself, but there's little incentive to update an sdk that's already good as-is and incur breakage on legacy tools.
• It's unclear how updating CNetworkVar will benefit the maintenance of SourceMod/Extensions or Metamod/Plugins
