dispatch: try and identify third-party extensions as sources of tracebacks Extension authors should explicitly declare their supported hg versions and include a buglink attribute in their extension. In the event that a traceback occurs, we'll identify the least-recently-tested extensionas the most likely source of the defect and suggest the user disable that extension. Packagers should make every effort to ship hg versions from exact tags, or with as few modifications as possible so that the versioning can work appropriately.

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
