Dual license as both released to public domain or under MIT license

Allow up to 4GiB memory page sizes

Fix an issue where large page sizes in conjunction with many threads waste a lot of memory (previously each heap occupied an entire memory page, now heaps can now share a memory page)

Fixed compilation issue on macOS when ENABLE_PRELOAD is set but not ENABLE_OVERRIDE

New first class heap API allowing explicit heap control and release of entire heap in a single call

Added rpaligned_calloc function for aligned and zero intialized allocations

Fixed natural alignment check in rpaligned_realloc to 16 bytes (check was 32, which is wrong)

Minor performance improvements for all code paths by simplified span handling

Minor performance improvements and for aligned allocations with alignment less or equal to 128 bytes by utilizing natural block alignments

Refactor finalization to be compatible with global scope data causing dynamic allocations and frees, like C++ objects with custom ctors/dtors

Refactor thread and global cache to be array based instead of list based for improved performance and cache size control

Added missing C++ operator overloads with ENABLE_OVERRIDE when using Microsoft C++ runtimes

Fixed issue in pvalloc override that could return less than a memory page in usable size

Added a missing null check in the non-hot allocation code paths
