APL\360 2741 patch for commadpt.c

driver mods for APL\360 December 2012 MHP <ikj1234i at yahoo dot com>

- circumvention for several race conditions
- new "eol" parameter specifies a byte value (ASCII), default 0x0D,
  which when received marks the end of the input line
- new "prepend" and "append" parameters to specify zero to four
  bytes to be prepended and appended (respectively) to input lines
  that have been received from terminals before being sent to the
  mainframe OS.  Typical use is to add Circle D and C around each
  input transmission (2741's for APL\360).  Bytes must be specified in
  S/370 channel format, not in ASCII.
- new terminal type "rxvt4apl" with 8-bit and character translation
  support for rxvt4apl in 2741 mode. Use the following conf definition entry
  0402 2703 dial=in lport=57413 lnctl=ibm1 term=rxvt4apl skip=5EDE code=ebcd
     iskip=0D0A prepend=16 append=5B1F eol=0A binary=yes crlf=yes sendcr=yes
       [all on a single line]
- negotiation to telnet binary mode when using rxvt4apl ("binary" parameter)
- send CR back to terminal when input line received ("sendcr" parameter)
- option to map 2741 NL to TTY CRLF sequence ("crlf" parameter)
- increase Hercules MAX_ARGS
