* 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.

* 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
