fix 'hf iclass' (#879)

Browse source 
* add loooong timeout for UPDATE command
* add flags FLAG_ICLASS_READER_INIT and FLAG_ICLASS_READER_CLEARTRACE
* don't overwrite trace buffer during 'hf iclass dump'
* fix long waiting time when start_time==0 in TransmitTo15693Tag()
* remove some additional debug prints
* refactoring: move helper functions from protocols.c to cmdhficlass.c
* add 'h' and '1' options to 'hf iclass reader' (from RRG repository)
* use correct key when only CreditKey is given in 'hf iclass dump'
* separate select_and_auth
* DropField() on errors
* dump last block in 'hf iclass dump'
* display correct memory size (number of blocks) in 'hf iclass reader' and dump
* more whitespace fixes
