Also allow flash to be separately enabled via PLATFORM_EXTRAS.
NOTE: this does *NOT* enable the serial number
in the bootrom. Still investigating options there.
* .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
