* feat: mkl-dnn initialize

* fix: structure of building

* fix: public final static

* fix: delete the dependencies of environments

* fix: skip tests

* add update dnn wrappers

* fix: dynamic load iomp5

* feat linear supports and some fix

* add more wrapper

* add lrn api

* fix: add bn and softmax

* fix: some fixes

* fix: mkl-dnn build

* feat: add get format api

* fix: add getSize

* feat: aligned memory

* add conv fuse relu api

* fix: add aligned storage

* add concat api

* fix: mkl envs for lib mkldnn

* fix: add mkl add method with 2 ptrs

* fix: update to Release

* fix: batch norm infer mode

* fix: update 0.5.0 -> 0.6.0

* add free (intel-analytics#5)

* feat: affinity for java thread

* fix: update core branch

* fix: delete the memset constant value for debug, and add affinity

* feat: add mkl-dnn fusion

* fix: memory format enum consistent with dnn

* feat: add auto format

* refactor: delete the MemoryFormat in MklDnn

* Memory should load MKLDnn (intel-analytics#6)

* refactor: move enums to seprate classes (intel-analytics#7)

* feat: add GetShape and GetFormat api

* fix: delete printf

* fix a bug

* add sum

* refactor: change name
