Perform StartupMessage length validation
...
PG provides a maximum size for a StartupMessage:
https://doxygen.postgresql.org/pqcomm_8h.html#a4c50c668c551887ac3a49872130349e3
Limiting the size ensures a malicious user doesn't send an
overwhelmingly large StartupMessage which could DOS a Go binary that
uses pgproto3.

Extend handling of unexpected EOF to the backend
...
In the original issue [1] and commit [2], support for unexpected EOF was
added to the frontend to detect when a connection was closed abruptly.
Additionally, this allows us to differentiate normal io.EOF errors with
unexpected errors in the backend.

Add support for identifying authentication messages
...
The pgprotocol overloads 'p' messages with PasswordMessage,
SASLInitialResponse, SASLResponse, and GSSResponse. This patch allows
contextual identification of the message by setting the authType in the
frontend and then setting this value in the backend when a
AuthenticationResponseMessage is received.

Fix reading interrupted messages
...
When an message is received and a timeout occurs after reading the
header but before reading the entire body the connection state could
be corrupted due to the header being consumed. The next read would
consider the body of the previous message as the header for the next.
