Improve logging for bluetooth_SDP_*AttributeRequest tests.
Add more logging statements and clarify error messages,
especially for the most frequent errors seen in the lab.
No functional changes to the behavior of the test.
ServiceSearchAttributeRequest:
- Split the giant and-ed line and make each sub-test fail instead of
returning False
- Add in the test name to failures
- Alter the current retry method to handle errors instead of bool
SDP tests:
- Split initial device reset into two sections which fail
independantly
- Set self.interactive before anything else, to avoid problems
if the later things fail
- Change output to hex instead of decimal where it makes sense
Client side code:
- Catch btsocket errors and timeouts and log more context info
- Add logging messages to low-level failures
- Check if adapter variable is None before using it
TEST=ran all bluetooth tests on a wificell and saw them pass
