Changes: - Improve table vs. array detection - Improve packing +-inf - Add multiple pack/unpack support - Add cmsgpack.safe module variant - Add local build infrastructure for easier testing - Add user-controlled unpack support limiting returned objects - Add Lua 5.3 compatibility - Remove an unnecessary malloc - Use Lua memory allocator instead of malloc for buffer creation Issues involved: - closes antirez#16 - allow multi pack/unpack by default - closes antirez#10 - unpack one/limit API added - closes antirez#13 and closes antirez#20 - use Lua allocator - closes antirez#15 - (included in antirez#16) - ignores antirez#22 because it's confusing - closes antirez#23 - fixed elsewhere - closes antirez#26 - extracted some useful parts from a difficult commit - closes antirez#28 - we started tagging versions again recently - closes antirez#27 - that failure case works for me now I merged commits with original author information where possible, but each commit required manual cleanup of one or more of: formatting fixes (no tabs, please), commit message fixes (more details please), extracting contents from a single 300 line commit with 5 different logical changes merged together, and general correctness checking after merging with newer code. As of this commit, all tests pass on Lua 5.1.5 and Lua 5.3-work2.

lua_newtable function is equivalent to lua_createtable(L, 0, 0).
The rehashing will cost too much time. The benchmark show the preallocate is faster ~30% than original version on random data.
