Moved the typedef of BinaryPacketProtocol into defs.h on the general principle that it's just the kind of thing that ought to go there; also removed the declaration of pq_base_init from ssh.h on the grounds that there's never been any such function! (At least, not in public source control - it existed in an early draft of commit 6e24b7d58.)

|
|
* to, such as opaque structure types and their associated typedefs,

|
* or macros that are used by other headers.
