util: don't log low-level I/O calls for HTTP peer

`hg debugwireproto` is useful for testing HTTP interactions. Possibly
more useful than `get-with-headers.py`. But one thing that makes it
annoying for mid-level tests is that it logs all API calls, such
as readline(). This makes output - especially headers - overly
verbose.

This commit teaches our file and socket observers to not log API
calls on functions dealing with data.

We change the behavior of `hg debugwireproto` to enable this mode
by default. --debug can be added to restore the previous behavior.

As the test changes demonstrate, this makes tests much easier to
read. As a bonus, it also removes some required (glob) over lengths
in system call results.

One thing that's lacking is knowing which side sent data. But we can
fix this in a follow-up once it becomes a problem.
