libXmu-1.2.1-160000.3.2

- Update to version 1.2.1
  * test: Add missing setjmp()
  * test: Add prototype for Xmureallocarray to silence warning

- Update to version 1.2.0
  * This release raises the minimum version of libXt required to 1.1.0
    (released in 2011), and for those builders who need to regenerate
    the autoconf files, raises the minimum version of autoconf required
    to 2.70 (released in 2020).

- Update to version 1.1.4
  This release includes two notable changes to XmuConvertStandardSelection():
  1) It no longer supports XA_IP_ADDRESS, which only supported IPv4 addresses
  and simply provided the output of gethostbyname() on the local hostname.
  2) XA_OWNER_OS no longer reports "BSD" for any Unix-like OS (including Linux)
  that it hadn't been coded to handle, instead relying on uname() where
  available to provide the OS name.
  The lack of bug reports about the previously misleading output for these
  suggests they're not widely used, with codesearch.debian.net only finding
  matches in libXmu and the rust bindings to libXmu, and not any consumers
  of these interfaces.

- Update to version 1.1.3
  * This minor maintenance release includes some small bug fixes,
    build configuration improvements and janitorial cleanups.
