* make uart_communication(), storeCommand() and getCommand() static in comms.c
* move receiver thread creation and respective mutexes to comms.c
* add mutex and signal for tx buffer
* use comms.c for flasher as well
* remove comm functions from client/proxmark3.h
* this completes isolating all USB communication related functions in comms.c
* don't assume a port to be defined by a name. Change parameter in OpenProxmark() to void*
* comms.c: set sp and serial_port_name to NULL when offline
* this should fix crashes reported in issue #497
* don't allow receiver thread to write directly into arbitrary main thread's memory
* instead use cmdBuffer[] for CMD_DOWNLOADED_RAW_ADC_SAMPLES_125K as well
* add timeout and warning options to GetFromBigBuf(), same as in WaitForResponseTimeoutW()
* move GetFromBigBuf() from data.c to comms.c
* remove data.c and data.h
* copy functionality from `hf 14a reader` to `hf 14a info`
* added command `hf 14a reader` with simple anticollision-select procedure.
* add parameters to `hf 14a reader`. may start and end acting as reader
* Improve 'Magic' Mifare tags detection
* Magic Mifare tags detection and version printing
* Magic s50/1k tag halt error correction for cload and csave
* hf mf c* commands for gen1b
* Use |= for bitwise operation
* gen1b: don't issue wipe command and don't expect response from WUPC1 magic command after a SELECT_UID: old UID display works in hf mf csetuid
* hf mf cgetsc compatibility for 4k
* hf mf csave compatibility for 4k
* hf mf cload compatibility for 4k, suppress halt errors messages for debug level 2
* Revert to MF_DBG_ERROR level in mifare_classic_halt() and don't issue the halt command for gen1b
* Improve 'Magic' Mifare tags generation detection & hf mf c* commands magic 4k compatibility
* Fix compile errors with MacOS
- _POSIX_C_SOURCE must not be defined for num_CPU()
* separate util_posix.c require changes in tools directory as well
* remove unnecessary self-include
- cleanup some header files and respective #includes
- rearrange functions (definition before first use)
- use SCNxxx instead of PRIxxx macros in scanf()
- use stdbool true/false instead of self defined TRUE/FALSE
- hf 14a reader now exits gracefully in case of proprietary anticollision sequence
- changed miller decoder to handle Topaz 8 data bits/no parity frames from reader
- started to implement hf list topaz
