* pop3d/extra.c (pop3_readline) : Since the length of the string

is known, we can use memcpy() and friends for string manipulations.
memXXX() functions are builtin in GNU C (gcc) and are much faster
then the strXXX() counterparts. Small change in the loop to take
advantage of this.

* pop3d/quit.c : The rfc1939 insist that after a QUIT, we must
release any resources and close the connection:
"Whether the removal was successful or not, the server
then releases any exclusive-access lock on the maildrop
and closes the TCP connection."  This was not done if error
occured while expunging, no we will close the connection and
notify the client of the error(ERR_FILE).
