httprepo: suppress the `real URL is...' message in safe, common cases.
When the actual and requested URL only differ by trailing slashes,
there is no need to warn. As an example, this easily happens when
accessing repositories on Bitbucket over HTTP(S).
As far as I could tell, there were no existing tests for this
behaviour.

Protocol between inotify clients and server:
Client sending query:
1) send protocol version number
2) send query type (string, 4 letters long)
3) send query parameters:
- For STAT, N+1 \0-separated strings:
1) N different names that need checking
2) 1 string containing all the status types to match
- No parameter needed for DBUG
Server sending query answer:
1) send protocol version number
2) send query type
3) send struct.pack'ed headers describing the length of the content:
e.g. for STAT, receive 9 integers describing the length of the
9 \0-separated string lists to be read:
* one file list for each lmar!?ic status type
* one list containing the directories visited during lookup
