gabor@google.com 60bd8015f2 Speed up Snappy uncompression, new Logger interface. - Removed one copy of an uncompressed block contents changing the signature of Snappy_Uncompress() so it uncompresses into a flat array instead of a std::string. Speeds up readrandom ~10%. - Instead of a combination of Env/WritableFile, we now have a Logger interface that can be easily overridden applications that want to supply their own logging. - Separated out the gcc and Sun Studio parts of atomic_pointer.h so we can use 'asm', 'volatile' keywords for Sun Studio. git-svn-id: https://leveldb.googlecode.com/svn/trunk@39 62dab493-f737-651d-591e-8d6aee1b9529		vor 13 Jahren
