Enable AoT and wamr-sdk, and change arguments of call wasm API (#157)

* Implement memory profiler, optimize memory usage, modify code indent

* Implement memory.grow and limit heap space base offset to 1G; modify iwasm build type to Release and 64 bit by default

* Add a new extension library: connection

* Fix bug of reading magic number and version in big endian platform

* Re-org platform APIs: move most platform APIs from iwasm to shared-lib

* Enhance wasm loader to fix some security issues

* Fix issue about illegal load of EXC_RETURN into PC on stm32 board

* Updates that let a restricted version of the interpreter run in SGX

* Enable native/app address validation and conversion for wasm app

* Remove wasm_application_exectue_* APIs from wasm_export.h which makes confused

* Refine binary size and fix several minor issues

Optimize interpreter LOAD/STORE opcodes to decrease the binary size
Fix issues when using iwasm library: _bh_log undefined, bh_memory.h not found
Remove unused _stdin/_stdout/_stderr global variables resolve in libc wrapper
Add macros of global heap size, stack size, heap size for Zephyr main.c
Clear compile warning of wasm_application.c

* Add more strict security checks for libc wrapper API's

* Use one libc wrapper copy for sgx and other platforms; remove bh_printf macro for other platform header files

* Enhance security of libc strcpy/sprintf wrapper function

* Fix issue of call native for x86_64/arm/mips, add module inst parameter for native wrapper functions

* Remove get_module_inst() and fix issue of call native

* Refine wgl lib: remove module_inst parameter from widget functions; move function index check to runtime instantiate

* Refine interpreter call native process, refine memory boudary check

* Fix issues of invokeNative function of arm/mips/general version

* Add a switch to build simple sample without gui support

* Add BUILD_TARGET setting in makefile to replace cpu compiler flags in source code

* Re-org shared lib header files, remove unused info; fix compile issues of vxworks

* Add build target general

* Remove unused files

* Update license header

* test push

* Restore file
