tests: add tests for poorly behaving HTTP server

I've spent several hours over the past few weeks investigating
networking failures involving hg.mozilla.org. As part of this, it
has become clear that the Mercurial client's error handling when
it encounters network failures is far from robust.

To prove this is true, I've devised a battery of tests simulating
various network failures, notably premature connection closes. To
achieve this, I've implemented an extension that monkeypatches the
built-in HTTP server and hooks in at the socket level and allows
various events to occur based on config options. For example, you
can refuse to accept() a client socket or you can close() the socket
after N bytes have been sent or received. The latter effectively
simulates an unexpected connection drop (and these occur all the
time in the real world).

The new test file launches servers exhibiting various "bad" behaviors
and points a client at them. As the many TODO comments in the test
call attention to, Mercurial often displays unhelpful errors when
network-related failures occur. This makes it difficult for users
to understand what's going on and difficult for server administrators
to pinpoint root causes without packet tracing.

Upcoming patches will attempt to fix these error handling
deficiencies.

"""Extension to make servers behave badly.
This extension is useful for testing Mercurial behavior when various network
events occur.
Various config options in the [badserver] section influence behavior:
closebeforeaccept
If true, close() the server socket when a new connection arrives before
accept() is called. The server will then exit.
closeafteraccept
If true, the server will close() the client socket immediately after
accept().
closeafterrecvbytes
If defined, close the client socket after receiving this many bytes.
closeaftersendbytes
If defined, close the client socket after sending this many bytes.
