Log Message:
Update to xrandr-1.2.3.

pkgsrc changes:
  Link with -lm, since the program uses fabs(). This failed on Linux of all
  platforms. NetBSD happens to have fabs() in libc, but the manpage states
  that -lm should be linked in, so do it for all platforms.

Changes:
  Update COPYING
  Add *current and +preferred to the --verbose output
  When invoked with no option, xrandr dumps existing modes
  Allow the same output to be specified several times on the command line
  Clarify the ability to manipulate multiple outputs in the manpage
  Verify crtc against previous config.
  Always reset other outputs using the best crtc.
  Add xrandr test suite.
  Improved test script.
  Use IDs for mode selection instead of hand-crafted \ 
<w>x<h>@<r> strings.
  More tests for ambiguous xrandr output.
  Some minor issues in test case fixed.
  Be more robust in test case if mode database is borked.
  Add more tests, mostly regarding crtc switching and uncloning.
  Add informational output for known issues.
  Add another test known to fail.
