When some of the same messages are redefined anywhere in a Go project,
the protobuf package panics (see
https://github.com/golang/protobuf/issues/178).

Since this package is internal, there is no way to work around it, as
one cannot use it directly, but also cannot define the same messages.

There is no downside in making the package accessible.

When opening the wallet, ask for passphrase as well as for the PIN
and return the relevant error (PIN/passphrase required). Open must then
be called again with either PIN or passphrase to advance the process.

This also updates the console bridge to support passphrase authentication.

* accounts/abi: fix name styling when unpacking abi fields w/ underscores

ABI fields with underscores that are being unpacked
into structs expect structs with following form:

int_one -> Int_one

whereas in abigen the generated structs are camelcased

int_one -> IntOne

so updated the unpack method to expect camelcased structs as well.

* fix slice unpack bug in accounts/abi

argument type and name were reversed
