- fix: ensure that FpgaDownloadAndGo() is always called before requesting

Browse source 
any memory from BigBuf[]. This is required because FpgaDownloadAndGo() might
  allocate, use, and free most of BigBuf[] when decompressing FPGA configs.
- cleanup: remove rests of deprecated "end of trace markers" (0x44)
