x11/x3270: update to suite3270-4.1ga11.

Removed some out-of-date documentation.
https://x3270.miraheze.org/wiki/Main_Page is the most up-to-date.

Improvements:
- Added a macros menu to c3270 and wc3270.
- Corrected support for the macros resource without a qualifying host
  name.
- The entire list of command-line options is now displayed only with the
  --help command-line option, not for every unknown option.
- Added the lineMode resource.
- Added the noTelnetInputMode resource.
- Added the wrap graphic rendition to b3270.
- Added the Pause() action.
- Changed the default for unlockDelay in all emulators from true to
  false. This is a very significant change.
- The overlayPaste resource is now set to true by default.
- GNOME desktop integration is now included.
- wc3270 now does continuous selections in NVT mode, and allows a single
  character to be selected.
- wc3270 no longer moves the cursor for mouse clicks in NVT mode.
- Double-clicking on a URL in x3270 (on most platforms) and in wc3270
  now opens that link in the browser.
- The session file folder is no longer marked as a system file, so
  backup software will not skip it.
- Added the SubjectNames() action and TlsSubjectNames query.
- Added the ability to set an accept host name to the wc3270 Session
  Wizard.
- Switched several actions that return values to explicitly return
  nothing.
- Added the ability to include the OIA in a PrintText() action screen
  image.
- Added the OIA to the screen image displayed by the HTTP server.
- Added validation of keymaps, macros and idle actions at init time.
- Added cursor blink support to wc3270.
- Added the SaveInput() action and RestoreInput() action.
- In b3270, error messages from failed host connection attempts are now
  labeled separately from other errors.
- Added the -subst option to the String() action.

Bug fixes:
- Fixed an issue in b3270 where the cursor would continue to be
  displayed when the host disconnected.
- APL characters were not displayed properly in x3270 in NVT mode, when
  using a 3270 font.
- On MacOS, the ./configure script would skip c3270 if it was not
  enabled explicitly.
- Fixed a number of typos in compiled strings and comments (courtesy of
  Philipp Kern).
- Fixed a c3270 crash seen on NetBSD.
- Fixed an issue with c3270 exiting prematurely, seen on NetBSD.
- Fixed an x3270 install issue (courtesy of Olaf 'Rhialto' Seibert).
- The last screenful of NVT mode text is no longer lost when scrolling
  backwards.
- The programs ar and ranlib are resolved dynamically now when building.
- Numeric fields no longer ignore non-numeric characters and commas,
  when the NumericLock resource is false. When it is true, commas are
  considered valid numeric characters.
- Proxy connections did not initialize TELNET state properly (courtesy
  of Andreas Krebbel).
- When running on Cygwin, child scripts (the Script() action, Execute()
  action and Prompt() action) failed with a bind error.
- When the print dialog was canceled, the PrintText() action and
  ScreenTrace() action would fail silently.
- The emulator would sometimes crash when a pending connection was
  broken.
- Windows error messages are now encoded using the selected code page,
  not the system ANSI code page.
- Fixed several scripting scenarios, such as aborting a Source() action,
  which would leave the keyboard locked.
- The String() action no longer requires an input field to be present in
  order to run.
- Corrected an issue where an empty error message would be displayed for
  a connection failure.
- Corrected a typo in a file transfer message name (courtesy of Philipp
  Kern).
- Added logic to ensure the icon directory exists when installing x3270
  on Linux (courtesy of Philipp Kern).
- Fixed the representation of APL underlined alphabetics in b3270 screen
  updates in NVT mode, and in the output of the Ascii() action.
- Fixed a crash when an action started with a comment (# or !).
- Fixed a version generation bug that prevented the code from building
  on MacOS when SOURCE_DATE_EPOCH was set.
- Corrected usage messages.
