Log Message:
x11/x3270: update to 4.2ga4.

4.1ga14

    The emulators no longer crash or hang when the oia option is used with the \ 
PrintText() action.

Known issues

    Resizing or maximizing the wc3270 window makes bad things happen. Please do \ 
not do this.
    Numeric fields do not allow the + and - characters to be entered if the \ 
numericLock resource is set to true. (Thanks to Roberto Ponti for the report.)
    The emulator will crash if the -port command-line option is used.
    The command-line syntax -set resource=value does not work on x3270.
    The -e command-line option to connect to a local process does not work on x3270.
    Cross-compiles using recent versions of MinGW warnings about printf formats.

Improvements
4.2ga4

    Unified the two ways of running Windows tests under the run_windows_tests.py \ 
script.
    If the host sends a TELNET WONT TN3270E (even if it has never sent WILL \ 
TN3270E) and the emulator is in TN3270E mode, the emulator will cancel TN3270E \ 
mode and send WONT TN3270E. This is not listed as a bug fix because it is a \ 
workaround for a bug on the host side, which should be sending DONT TN3270E.
    Added the retry resource to retry host connections, even if the reconnect \ 
resource is not set to true.
    Added more validations for bad host writes and pop-ups to report them.
