Adam Sawicki d3a85f0dc3 Refactored virtual allocator. (COMPATIBILITY BREAKING!) Added TLSF algoritym. 
Refactored virtual allocator: Added type VmaVirtualAllocation, member VmaVirtualAllocationInfo::offset, changed parameters of vmaVirtualAllocate, vmaVirtualFree, vmaSetVirtualAllocationUserData, vmaGetVirtualAllocationInfo.

Added TLSF algorithm: Added VMA_POOL_CREATE_TLSF_ALGORITHM_BIT, VMA_VIRTUAL_BLOCK_CREATE_TLSF_ALGORITHM_BIT.

Some internal refactoring.

Improved documentation: Grouped API elements into Doxygen modules.

Code mostly by @medranSolus.
