CMD_SPIFFS_DOWNLOAD read the whole file into BigBuf first. BigBuf_calloc()
takes a uint16_t while the size is a uint32_t, so a 64K file allocated zero
bytes and anything larger wrapped to a short buffer the file was then read
straight past the end of. rdv40_spiffs_read_stream() opens the file once and
hands out one frame at a time, so the size never reaches the allocator, and the
SPIFFS path now honours start_index. Verified with an 80K round trip: upload,
download, byte identical.
The same BigBuf_calloc(filesize) wrap was in copy_in_spiffs(); it now copies in
SPIFFS_WRITE_CHUNK_SIZE chunks.
Separately, every flash failure was invisible. SPIFFS_CHECK_RES() only treats a
negative result as an error and the HAL hooks returned 128/129/130, so SPIFFS
saw success. The erase path was worst: Flash_Erase4k() only reports that the
command was sent, both Flash_CheckBusy() results were discarded, and
'return (SPIFFS_OK == erased)' yields 1 on failure. A flash dump from a device
that hit this showed one block written without being erased - its object index
header held '0x14000 & 0x10000', and the filename ANDed away to empty. Erases
are now read back and retried, and the HAL returns real SPIFFS error codes.
Flash_Write() returned len unconditionally even after a rejected page, which
also defeated the 'res == payload->len' check in CMD_FLASHMEM_WRITE.
Feedback, so none of this is silent again: CMD_SPIFFS_WRITE answers with the
SPIFFS result, the client aborts on the first refusal and names the byte it
stopped at, dl_it() checks the terminator status, and both transfer directions
print inline progress.

* .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
