stlink-org#1216 refactoring of common.c

File divided to some parts. Functions with "flash" in names extracted to common_flash.c, with "option" extracted to option.c etc.
Removed unnecessary headers.
Removed one single function which was used nowhere.
And so on.
Project built under Windows and seems to be working.
