dropbear: added 0.47
Note from upstream author about 0.47 and fix for older: This release also fixes a potential security issue, which may allow authenticated users to run arbitrary code as the server user. I'm unsure exactly how likely it is to be exploitable, but anyone who's running a multi-user server is advised to upgrade.
