ssh: limit the size of the internal packet queue while waiting for KEX

In the SSH protocol, clients and servers execute the key exchange to
generate one-time session keys used for encryption and authentication.
The key exchange is performed initially after the connection is
established and then periodically after a configurable amount of data.
While a key exchange is in progress, we add the received packets to an
internal queue until we receive SSH_MSG_KEXINIT from the other side.
This can result in high memory usage if the other party is slow to
respond to the SSH_MSG_KEXINIT packet, or memory exhaustion if a
malicious client never responds to an SSH_MSG_KEXINIT packet during a
large file transfer.
We now limit the internal queue to 64 packets: this means 2MB with the
typical 32KB packet size.
When the internal queue is full we block further writes until the
pending key exchange is completed or there is a read or write error.

Thanks to Yuichi Watanabe for reporting this issue.
