Because no localdisk means either s3 or google is the primary,
and none of them support efficient replication.
1) Added a dummy synchandler constructor for when config has "idle"
2) Set "idle" for synchandler config when no localdisk
3) fixed corresponding tests
Also:
- added error (and test) when no localdisk and both s3 and google
in config
- added s3 + mysql test

-pkg/server/share.go handles share(d) blobs.
-pkg/blobserver/gethandler no longer deals with share blobs
and has been rewritten like the other handlers (no more auth
in there).
-client and signhandler changed accordingly.
-serverconfig: auth moved up in makeCamliHandler
-share parameter added to the user level and low level config.
-share URL is now http(s)://host[:port]/[prefix/]share/sha1-xxxx.
