Subject: wl_array: Set data to invalid address after free
Explicitly set the data member to an invalid memory address during
wl_array_release, such that re-using a freed wl_array without re-initializing
causes a crash. In addition, this pointer assignment makes wl_array_release
testable.
Define a constant for the invalid memory address, and add documentation about
this behavior, starting at libwayland version 1.13.
