file: use 64bit indexing for block size #296

Gottox · 2024-09-05T11:52:46Z

This patch changes the block size and block compression functions to use 64bit indexing. From reading the specs, I came to the conclusion that the block size table can be larger than 4Gi entries. (to be exact, I believe that the worst case block table is:

UINT64_MAX (max file size) / 4096 (minimal block size)

While we don't support files that large yet, we lay the foundation to support them in the future.
