c9c1c323cd* mpqapi FStreamWrapper: Fix silly bugs
* mpqapi cleanup
1. Do not rely on stream positions for getting the initial file size.
2. Remove most `seek` calls that were unnecessary.
3. Replace magic numbers with constants.
4. A class to manage archive lifetime and all associated data.
* Revert "Revert "mpqapi: Log all fstream calls""
This reverts commit e08007670f.
* mpqapi: Fix saves on Amiga
Works around https://github.com/bebbo/libnix/issues/30
* mpqapi: Fix logging format specifiers
This fixes fstream logging on Amiga
* mpqapi: Do not ResizeFile unless it was modified
* Add tests for file_util
* mpqapi: Replace malloc/free with new[]/delete[]
* mpqapi: Keep track of size instead of using tellp
This reduces log noise and reliance on `tellp`.
* mpqapi: Refactor mpqapi_write_file_contents
* mpqapi: Ensure we don't seekp beyond EOF on Amiga
* mpqapi: Minor fixes
* mpqapi: Fix FSTREAM_CHECK on Windows
* mpqapi: Remove undefined methods from header
