This patch removes the creating of an additional writeback_fid for opened files. The patch addresses problems when files were opened write-only or getattr on files with dirty caches. This patch also incorporates information about cache behavior in the fid for every file. This allows us to reflect cache behavior from mount flags, open mode, and information from the server to inform readahead and writeback behavior. This includes adding support for a 9p semantic that qid.version==0 is used to mark a file as non-cachable which is important for synthetic files. This may have a side-effect of not supporting caching on certain legacy file servers that do not properly set qid.version. There is also now a mount flag which can disable the qid.version behavior.
