Fixes #4586.

Make tools/install.py work with python 2.5

2.5 is still fairly widespread and does not include a json lib as
standard. Most python folk will have simplejson if they are in that
boat.

In general it seems a bit tricky to solve this perfectly...

Reject negative offsets in SlowBuffer::MakeFastBuffer(), it allows
the creation of buffers that point to arbitrary addresses.

Reported by Trevor Norris.

This test starts two clustered HTTP servers on the same port.
It expects the first cluster to succeed and the second cluster
to fail with EADDRINUSE.

Reapplies commit cacd3ae, accidentally reverted in a2851b6.

This reverts commit 45024e7.

It's making test/simple/test-tls-check-server-identity.js fail:

  AssertionError: Test#4 failed: { host: 'b.a.com',
    cert: { subject: { CN: '*.a.com' } },
    result: false }
      at <omitted>/test/simple/test-tls-check-server-identity.js:201:10

This reverts commit 30e2370.

Works properly with b4b750b
