[Sync] Move 'sync' target to sync/

Also move related test files.

Move WriteNode::UpdateEntryWithEncryption to nigori_util.h.

Clean up defines and dependencies.  In particular, get rid of SYNC_ENGINE_VERSION_STRING and hard-code the string in the single place it's used.

Rename data_encryption.* to data_encryption_win.* and add a pragma for crypt32.lib.

Clean up exit-time constructor warnings in sync{able,er}_unittest.cc.

Remove some unused files.
