https://github.com/matrix-org/synapse/issues/2187 contains a report of a port
failing due to nul characters somewhere in the search table. Let's try dropping
the offending rows.

When fetching the list of tables from the postgres database during the
db port, it is assumed that the tables are in the public schema. This is
not always the case, so lets just rely on postgres to determine the
default schema to use.

This is what I get for not proofreading

This also fixes a bug where the port script would explode when it
encountered the newly added boolean column
`public_room_list_stream.visibility`

Replace the bash/perl gen_password script with a python one, and write a note
on how to use it.

Seperate scripts/ into scripts/ and scripts-dev/, where scripts/* are automatically added to the package
