[PATCH 0/9] Misc memory leak fixes

[Peter Hutterer]

The test case was:
  valgrind --leak-check=full --show-reachable=yes Xvfb
forcing two server regenerations by running xterm against it 3 times. 

Before:
==31654== LEAK SUMMARY:
==31654==    definitely lost: 3,720 bytes in 11 blocks
==31654==    indirectly lost: 287,964 bytes in 2,273 blocks
==31654==      possibly lost: 0 bytes in 0 blocks
==31654==    still reachable: 136,104 bytes in 1,733 blocks
==31654==         suppressed: 0 bytes in 0 blocks

After:
==13190== LEAK SUMMARY:
==13190==    definitely lost: 960 bytes in 8 blocks
==13190==    indirectly lost: 123,552 bytes in 572 blocks
==13190==      possibly lost: 0 bytes in 0 blocks
==13190==    still reachable: 27,724 bytes in 77 blocks
==13190==         suppressed: 0 bytes in 0 blocks

The majority of the indirectly lost are in glx, but afaict they are false
positives:
==13190== 61,344 bytes in 284 blocks are indirectly lost in loss record 52
of 54
