tf2attributes x64 port (Linux only)

This exists in case Valve happens to kill off x86 servers and we don't yet have a better way to handle addresses.

Requirements

Build SourceMod using alliedmodders/sourcemod/#2159

My fork of Port64 Malifox/port64

• You may need to recompile any plugins previously using the original Port64 include, no code changes needed. I added an optional offset to Port64_GetEntityAddress to remove the additional Port64_Add step and native overhead. I didn't really think I would be porting the entirety of tf2attributes at the time and kind of hoped a more official solution would come along. Not really sure what to do about the additional methods I added to Address64 either in the event Valve deletes x86 servers and people actually need to use this and I made things messier by having a fork.

Notes

The following natives will require changes to be made to the plugin that uses them due to passing an array(Address64):

• TF2Attrib_GetByName
• TF2Attrib_GetByDefIndex
• TF2Attrib_SetDefIndex
• TF2Attrib_GetDefIndex
• TF2Attrib_SetValue
• TF2Attrib_GetValue
• TF2Attrib_SetRefundableCurrency
• TF2Attrib_GetRefundableCurrency

I didn't test the heap-allocated management of non-networked attributes yet.
