Refine binary size and fix several minor issues (#104)

Browse Source 
* 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
