fix hf mf sim (issue #412) (#419)
* move to separate files mifaresim.[ch]
* check CRC of commands
* don't execute commands without successfull authentication
* ensure correct timing of REQA, WUPA, ANTICOL and SELECT responses
* trace reader commands immediately, only fix start time after tag response. Decreases time to be ready for next reader command.
* remove iso14443-4 remnants
* trace raw reader commands instead of decrypted ones
* some refactoring
* fix hf mf sim
* timing: decrease time to get ready for new reader commands

Check keys in hf mf nested and hf mf chk (#414)
Improve hf mf chk and hf mf nested
* hf mf chk. added interrupt of procedure by usb
* extract mifare default keys into separate module
* arm side multisector `hf mf chk`
* hf mf nested. change key search procedure
* hf mf nested. added key check after we have found a key.
* small fix hf list f
* hf mf chk. add timeout (arm side) and some tweaks.
* Fix typo in hf mf csave help
* Fix gcc 7 warning: '~' on an expression of type bool [-Wbool-operation], use logical ! not instead of ~
* Fix gcc 7 warning: ‘memset’ used with length equal to number of elements without multiplication by element size [-Wmemset-elt-size]
* Fix gcc 7 warning: warning: duplicate ‘const’ declaration specifier [-Wduplicate-decl-specifier]
* adjust LFSim to download lf fpga prior to setting emulation buffer to prevent buffer overwrite condition if you are coming from HF fpga.
* fix lf sim big buff overwrite with fpga download. Move fix to the buffer download cmd.

Indala fixes - set accurate preamble and start of.. (#385)

also adjust 224 bit demod and clone to output and input in PSK2 instead
of PSK1 as this appears to be most common for this format.

- Check button press when there is NOFIELD, so we can exit also without FIELD
- struct nonces_t is moved to include/mifare.h so client and arm has the same definition

adjust lf simulation - fix one bug + attempt... (#369)
... to speed up the loops waiting for carrier signal to go high or low
by only checking for a halt (button press or usbpol) every 1000th loop

some users were experiencing modulating reactions to be too slow.
add fsk cleaning / demod tool fsktonrz
- used old fskdemod for HID and adjusted it to build the tone tables for any fsk model detected or given. using the tone tables we are able to convert the fsk to clear strong NRZ/ASK even with very weak fsk waves.
- also fixed a small textual bug in `lf search u` output
- also added more graph clearing code to help ensure the demod overlay doesn't show when it shouldn't...
- and improved strong NRZ clock detection.
- fixed bugs in places it used old static values instead of dynamic read values. and removed redundant items.

Refactoring uart interface (#341)
* uart: Major cleanups
- Adds documentation to the uart API.
- Fixes a buffer overflow issue in `uart_receive`, where the maximum parameter was ignored.
- Splits the maximum length and bytes recieved variables in `uart_receive`.
- Downsizes the receive buffer to the minimum required, saving 16MiB of RAM at runtime.
- Refactors the POSIX and Win32 implementations of uart into separate files.
- Removes the unused `uart_{get,set}_parity` functions, which were not implemented on Win32.
endless loop in reader if no tag was found
button press on pm3 did not cancel.
led_b was left on in some cases
also moved 14b detection to last in hf search to help speed up the
command for the other tags. 14b is slow (does multiple tests)
Thanks to @Fl0-0 and @pwpiwi for their idenfication of some of the
issues.
EM410x bruteforcing changes: Load the whole file at once, pause delay as parameter, stop the execution on key press and EM410x conversion to signal function.
