[tor-dev] Logging [Enhancement]

[grarpamp]

- An FYI, found while grokking, thanks.
- These various log entries could really have their format normalized sometime.
- If it's going to tell us why it's giving up in one case, it should
do so in all cases.
- The fingerprints should be printed instead of the ambigous router names.
- Eliminate personal pronouns 'We'.
- Remove 'Have'.
- Shorten seconds to sec.
- Change 'get a connection' to 'build a circuit'
- Remove quoting, parenthesis, etc. Or create, and consistently use,
parseable entries.

We tried for 15 seconds to connect to '[scrubbed]' using exit
'Unnamed'. Retrying on a new circuit.
Have tried resolving or connecting to address '[scrubbed]' at 3
different places. Giving up.
Tried for 123 seconds to get a connection to [scrubbed]:80. Giving up.
Tried for 120 seconds to get a connection to [scrubbed]:80. Giving up.
(waiting for circuit)
Tried for 120 seconds to get a connection to [scrubbed]:0. Giving up.
