* .h include only the strict minimum for their own parsing * this forces all files to include explicitment their needs and not count on far streched dependencies * this helps Makefile to rebuild only the minimum * according to this rule, most standalone .h are now gone * big app.h is gone * remove seldom __cplusplus, if c++ happens, everything will have to be done properly anyway * all unrequired include were removed * split common/ into common/ (client+arm) and common_arm/ (os+bootloader) * bring zlib to common/ * bring stuff not really/not yet used in common back to armsrc/ or client/ * bring liblua into client/ * bring uart into client/ * move some portions of code around (dbprint, protocols,...) * rename unused files into *_disabled.[ch] to make it explicit * rename soft Uarts between 14a, 14b and iclass, so a standalone could use several without clash * remove PrintAndLogDevice * move deprecated-hid-flasher from client to tools * Makefiles * treat deps in armsrc/ as in client/ * client: stop on warning (-Werror), same as for armsrc/ Tested on: * all standalone modes * Linux
