transports: Resize socket send buffer if needed

This was originally added in openbmc/pldm to make the socket send buffer
big enough to send a message if the message is longer than the current
send buffer size.

When you call set_sock_opt with buffer size X, given that X is within a
certain range, the send buffer is actually set to 2*X. get_sock_opt
returns the 2*X value, not X. So add in some helper functions.
