7ecd43080c Improve naming of global variables 
Now, the output_* variables contain paths to files to be created by the
compiler and the cached_* variables contain paths to files in the cache
directory.

5ea294ef76 Force new hash sums 
All hash sums will from now on be different from those calculated by ccache
2.4, instead of only hash sums for compressed files. This makes hash sums for
compressed and uncompressed files equal again, which reopens for conversion
between compressed and uncompressed files, should the need arise.

3eaee4c2a7 Bail out on profiling flags 
GCCs options -fprofile-generate and -fprofile-use are used for profile guided
optimization. It depends on the ability to locate the profile data files
(.gcda) after running the executable with the training data. However, ccache
prevents the compiler from finding the correct profile data file. Therefore the
following patch disables the caching when one of the -fprofile-generate
-fprofile-use flags is found.

42273c937f Let compressed files get different hash sums than uncompressed 
This is to avoid problems when older ccache versions (without compression
support) access the cache.

9bd32895fd Also store preprocessor standard error output in .stderr file

63a505fe79 Fix statistics and cache cleanup for files generated by direct mode 
The statistics counters "files in cache" and "cache size" now only include
object files. It's not worth the effort to keep track of the .manifest, .d and
.stderr files since the cache size is dominated by the object files, and it's
unlikely that anyone is bothered by du(1) having a different opinion (which
also was the case before anyway). Consequently, the "max file" and "max cache
size" settings now specify thresholds for object files count and size.

befbba943b Rewrite include directory option arguments into relative to get better hit rate 
A secondary effect is that paths in the standard error output produced by the
compiler will be normalized.
