thread fix, debug output

parcelUnitTest.py:
- changed generateTestData to generate a variable number of files
- increased the size & number of test files generated

crypto.cpp:
- added some debug output

debug_output:
- fixed output of address in print_bytes

files.cpp/h:
- Added routines to handle whether the peer and auth are finished and
the encryption is verified
- whitespace

parcel.cpp/h:
- added flag for master to xfer_t struct
- added a few waits for encryption to verify
- fixed crypto length to what it should be for 128 (might want to make
this detect encryption type)

- commented out some debug output

udpipe.h:
- added flag for master to rs_args and thread_args structs

udpipe_client/server.cpp:
- pass along flag for master
