The iucvtty_read_msg() now receives the entire message header.
Perform message header checks for specific message types where the
payload length is clearly defined. Also this needs to be done prior
starting the message chunk processing because the message datalen
field will be adjusted based on the read chunks.

If iucvtty_read_data() receives message data and reads less than
MSG_DATA_OFFSET, out-of-bound reads will happen.
Correct and improve the receiving path by always reading the entire
message header. Also improve the "residual" message data handling by
replacing and processing every message now as chunk.

Improve handling of TERM environment processing by validating
the received terminal name. If the terminal name is not valid,
a message will be displayed and the default terminal will be used.
