Issue 2 move folders and use deep path include file names to prevent collisions (#4)
* moving folders and files and adjust server demo build * Fix Makefile for apps/server on Linux * fix unit test source file folders * fix datetime convert UTC functions. Add Code::Blocks project for datetime testing * added some ignore extensions * disable parallel make option * fix build for abort, dcc, and epics apps * fix build for dcc, epics, error, and getevent apps. * Fixed building of all apps * fix the ipv4 to ipv6 router app build * Change indent style from Google to Webkit * make pretty to re-format style * removed common Makefile since we already had one and two was too many * remove scripts from root folder that are no longer maintained or used * remove mercurial EOL and ignore files for git repo * remove .vscodeconfig files from repo * tweak clang-format style * clang-format src and apps with tweaked style * added clang-tidy to fix readability if braces in src * result of make tidy for src and apps * fix clang-tidy mangling * Added code::blocks project for BACnet server simulation * added code::blocks linux project for WhoIs app * update text files for EOL * fix EOL in some files * fixed make win32 apps for older gcc * Removed Borland C++ Makefile in apps. Unable to maintain support for Borland C++ compiler. * created codeblocks project for apps/epics for Windows * fixing ports/xplained to work with new data structure. * fix ports/xplained example for Atmel Studio compile * fix ports/stm32f10x example for gcc Makefile compile * fix ports/stm32f10x example for IAR EWARM compile * fix ports/xplained timer callback * fix ports/bdk_atxx_mspt build with subdirs * fix ports/bdk_atxx_mspt build with subdirs * updated git ignore for IAR build artifacts * updated gitignore for non-tracked files and folders * fixed bdk-atxx4-mstp port for Rowley Crossworks project file * fixed bdk-atxx4-mstp port for GCC AVR Makefile * fixed atmega168 port for IAR AVR and GCC AVR Makefile * fixed at91sam7s port for IAR ARM and GCC ARM Makefile * removed unmaintainable DOS, RTOS32, and atmega8 ports. Updated rx62n (untested). * changed arm7 to uip port
