httppeer: wrap HTTPResponse.read() globally...
httppeer: wrap HTTPResponse.read() globally There were a handful of places in the code where HTTPResponse.read() was called with no explicit error handling or with inconsistent error handling. In order to eliminate this class of bug, we globally swap out HTTPResponse.read() with a unified error handler. I initially attempted to fix all call sites. However, after going down that rabbit hole, I figured it was best to just change read() to do what we want. This appears to be a worthwhile change, as the tests demonstrate many of our uncaught exceptions go away. To better represent this class of failure, we introduce a new error type. The main benefit over IOError is it can hold a hint. I'm receptive to tweaking its name or inheritance.

#require killdaemons serve zstd
Client version is embedded in HTTP request and is effectively dynamic. Pin the
version so behavior is deterministic.
$ cat > fakeversion.py << EOF

$ hg init server0
$ cd server0
$ touch foo
$ hg -q commit -A -m initial
Also disable compression because zstd is optional and causes output to vary
and because debugging partial responses is hard when compression is involved

Failure to accept() socket should result in connection related error message

So ensure the process is dead.)
