1. elfloader for shared object example: TencentOS-tiny\examples\elfloader_shared_object keil: TencentOS-tiny\board\TencentOS_tiny_EVB_MX_Plus\KEIL\elfloader_shared_object 2. elfloader for relocatable object: example: TencentOS-tiny\examples\elfloader_relocatable_object keil: TencentOS-tiny\board\TencentOS_tiny_EVB_MX_Plus\KEIL\elfloader_relocatable_object 3. TODO: - add icache/dcache flush when module is loaded - support more relocation type in elfloader_arch_relocate
