ADD: found some new default keys
ADD: changed alot of memorys buffers to use constant values. like usbbuffer sizes, tracelogs, etc etc
ADD: all changes Peter filmoore has in his pull request.
The user may specify a delay between PACE nonce requests. Using no delay between subsequent issues of the USB command may lead to errors in the USB communication.
Until test results show that the delay can be fixed or left out completely the user has to test what value is safe to use.
This fixes errors "Read only 40 instead of requested 64 bytes!" (if the correct delay is used, e.g. 3 seconds for 16 byte nonces).
-new files armsrc/epa.[ch] for ePA (electronic "Personalausweis") related functions
-Offers elementary functions (EPA_PACE_MSE_Set_AT etc.)
-Also offers one new USB command: EPA_PACE_Collect_Nonce
-created new command subtree in client: client/hfepa.[ch] ("hf epa")

-more to come
