any memory from BigBuf[]. This is required because FpgaDownloadAndGo() might
allocate, use, and free most of BigBuf[] when decompressing FPGA configs.

fix: fpga_compressor file size check

fix bug in pskdemod return value if no samples...
... caused crash in data psknexwatchdemod if no samples were in the
graphbuffer.
also fixed hf mfu wrbl and rdbl to allow printing of help without a tag

Add PACE replay functionality
This function allows the user to specify APDUs which are sent to a card
supporting the PACE protocol. The response times are measured and
printed.
The code was pulled from the old Google Code repository (branch "epa")
and modified to fit into the new code base.

- fix: better approximation of signal amplitude to avoid false carrier detection (iso14443b.c)

have the time to do so).

also delete *.bin and fpga_compressor when "make clean".
Add target to make fpga_compressor when client is not yet compiled.

Compress the .data section as well (saves another 4KBytes and comes for free)
zlib tuning: prevent fpga_compress from generating fixed code blocks
armsrc/Makefile: replace osimage with fullimage
fpga_compress: interleave (combine) fpga_lf.bit and fpga_hf.bit before compression.
fpga_loader.c: change to unweave fpga_lf and fpga_hf accordingly
prepare fpga_compress, fpga_loader and Makefile to handle more than two FPGA config files
revert removal of fullimage Makefile target. Remove osimage instead.
replaced gzip with an own compressor tool (fpga_compress.c, based on zlib)
This allows to remove the gzip header support and the z_crc32.[ch] files
