IVP/VPhysics changes

[RaphaelIT7]

IVP still has some issues, and some improvements could be made.
If you find any, please report them here, including crashes and such.
If you want any changes/have ideas for improvements, feel free to suggest them.

How to test

Linux

you can normally install holylib BUT the ghostinj.dll is required for the IVP replacement to work.
Additionally you have to add -holylib_replaceivp to the command line.

Windows

1. you need to rename the holylib dll to vphysics.dll
2. rename the vphysics.dll inside garrysmod to vphysics_orig.dll
3. Now place the renamed holylib dll into the bin/win64 directory where the original vphysic.dll was renamed.

General (Both 32x & 64x)

• Fix ragdolls being completely broken
• Raise MAX_ALLICATION to solve crashes when hitting allocations limit (See 3396614)

64x Only issues

• Fix Objects having wrong material flags?
• Fix Object impact sounds being all the same?

64x Linux

• Fix a crash related to CVPhysicsParse

IVP Bugs

• When a lot of objects collide with each other and a lot of friction is created objects can enter a freezed state without being freezed.

Linux64 was fixed with f6dce94
Its more of a workaround as we fallback to the original vphysics dll for this specific function:
IVPhysicsKeyParser *CPhysicsCollision::VPhysicsKeyParserCreate( vcollide_t *pVCollide )
since its 64x only and something in our IVPhysicsKeyParser seems to be broken.

This workaround also seem to have fixed all other 64x Issues.
I feel like our IVPhysicsKeyParser class is very broken.

I think this is very cool, but i don't understand what the purpose of this is. Optimize vphysics? Fix crashes with it?

[RaphaelIT7]

Mainly to fix crashes and maybe even some bug fixes or some features related to IVP.
Also 64x currently has Facepunch/garrysmod-issues#5968 which may also be solved for servers using this until Rubat updates vphysics.

@RaphaelIT7: By the way the issue does exist in most Valve's multiplayer games such as TF2, CSS and HL2:DM. These game are currently the most up to update Source 1 games as recently updated with the 20th anniversary of HL2.

In the issue there is a test map + source for reproduction that runs on every game we have tested. Apparently it has something to do with the map containing long but thin geometry too.
