Bug fixes:

  - Fixed entry_size field for result entries. This bug affected the
    recompression feature (“-X”/“--recompress”) in ccache 4.5.

  - The actual compression level is now once again stored in the cache entry
    header.

  - Corrected error handling for non-constructible secondary storage backends.
    For instance, this avoids a crash when a Redis server can't be reached.
