Run all Cbuf_Execute calls in the main thread. This should fix every problem related to (but not only):
* Connecting to server while RUI dialogue is still open.
* Connecting to server while in an active game.
* Running 'weapon_reparse'.
* Fix all compiler error for GameSDK on S0 and S1.
* Remove some unused patterns and globals (launch performance gains of 100ms).
* Remove most duplicate patterns.
* Relocate globals from engine to a more appropriate location.
* Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known).
* Renamed some vars to fit the naming convention used in the SDK.
* Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.
Renamed to EGlobalContext_t and used globally for all context types combined into one (required for rcon messages for example, as we do native and script messages, while also retaining colors).
* Removed some unused signatures.
* Named 2 CBaseFileSystem methods, and applied them to 'MOD_ProcessPakQueue()'.
* Renamed 'qword_1671061C8' to 'g_pMTVFTaskItem'.
* Renamed 'g_pMapVPKCache' to 'g_szMTVFItemName'.
* Only set first byte to 0 in 'g_szMTVFItemName' (actual size is 0x100, not 0x40).
* Use GetVirtualMethodTable for VFTable pointers.
* Pack CClientState to 4 bytes (this aligns it properly in memory).
* Use CClientState members directly for setting m_bRestrictServerCommands/m_bRestrictClientCommands.
Allow searching for multiple occurrences, the main reason for this addition is that some RTTI object locators reference 2 (or more) VFTables, the ConVar class is a good example., where we have 2 separate VFTables, one implementing ConCommandBase (which implements its own IConVar), the other implementing just IConVar for ConVar (2 VMT pointers in one class).
* Use proper types reflecting assembly from the engine in 'CBitRead::Seek' (some values are 64bit, either changed by Respawn or the compiler used by Respawn).
* Confirmed changes made to NETMSG_TYPE_BITS (now 511 instead of 255) and NETMSG_LENGTH_BITS (now 12 which is 511 max instead of 255).
* Confirmed msg HUD types.
* Enforce NET_MIN_MESSAGE on 'SVC_UserMessage::Process'.
* Remove unnecessary padding and add proper symbols where padding was actually used.
* Improve readability.
* Free allocated iterator memory.
* Enforce FCVAR_HIDDEN ConVar's in ImGui console (there are only 17 ConVar's marked 'hidden', and most of these are stryder/platform related stuff. This is usefull for if we ever wish to create a hidden cvar).
Addressed:
* 'Expression: vector subscript out of range' (we only ever ensured capacity upon construction).
* Compiler error as AssertMsg1 is unimplemented, used Assert instead.
This commit breaks the indev branch for the time being (this will be solved very soon).
We no longer mask off dev flags from every commandbase, we only mask them off from the essential ones (map, connect, give, etc..), unless the SDK is launched as dev, then we mask everything off like usual, but this time at initialization and not whenever we encounter a var with this flag.
