storeDirSwapLog()

void storeDirSwapLog	(	const StoreEntry *	e,
		int	op
	)

An entry written to the swap log MUST have the following properties.

1. It MUST be a public key. It does no good to log a public ADD, change the key, then log a private DEL. So we need to log a DEL before we change a key from public to private.
2. It MUST have a valid (> -1) swap_filen.

storeDirWriteCleanLogs

Writes a "clean" swap log file from in-memory metadata. This is a rewrite of the original function to troll each StoreDir and write the logs, and flush at the end of the run. Thanks goes to Eric Stern, since this solution came out of his COSS code.
