core, lib, modules: restructured source code tree

- new folder src/ to hold the source code for main project applications
- main.c is in src/
- all core files are subfolder are in src/core/
- modules are in src/modules/
- libs are in src/lib/
- application Makefiles are in src/
- application binary is built in src/ (src/kamailio)
