====================
Task local data bug fixes and improvement

This patchset fixed three task local data bugs, improved the
memory allocation code, and dropped unnecessary TLD_READ_ONCE. Please
find the detail in each patch's commit msg.

One thing worth mentioning is that Patch 3 allows us to renable task
local data selftests as the library now always calls aligned_alloc()
with size matching alignment under default configuration.

v1 -> v2
 - Fix potential memory leak
 - Drop TLD_READ_ONCE()
