Bug fixes:

  - Fixed a bug related to object file location in the dependency file (if
    using “-MD” or “-MMD” but not “-MF” and the build directory is not the same
    as the source directory then the object file location in the “.d” file
    would become incorrect). This fixes regression in ccache 3.7.5 introduced
    by the bug fix related to EDG-based compilers. Note that this removes
    support for EDG-based compilers again. (A better fix for this is planned
    for ccache 4.0.)

  - Removed the unify mode since it has bugs and shortcomings that are non-
    trivial or impossible to fix: it doesn’t work with the direct mode, it
    doesn’t handle C++ raw strings correctly, it can give false cache hits for
    “.incbin” directives, it’s turned off when using “-g” and it can make line
    numbers in warning messages and “__LINE__” macros incorrect.

  - mtime and ctime values are now stored in the manifest files only when
    sloppy_file_stat is set. This avoids adding superfluous manifest file
    entries on direct mode cache misses.

  - A “Result:” line is now always printed to the log.

  - The “cache miss” statistics counter will now be updated for read-only cache
    misses, making it consistent with the cache hit case.
