This patch reduces the max-module-size of the project to 3600, which is
slightly larger than the currently largest module (baring backend.py,
which got a free pass): config.py

In an efford to reduce the module size to something more reasonable, the
next person to hit the wall will find a nice reminder: Please reduce the
maximal module size further when possible.

This is to conform with our style guide.

This setting was added in and becomes necessary with pylint 1.3.

In order to check for the correctness of the accesses to fields of objects,
pylint uses astng, but this is known to fail on some dynamically generated
classes. Still, newer pylint versions are stricter at performing this check, and
therefore fail while testing our codebase. Disable the checking of a few
selected classes that incur in this problem.

Recent versions of pylint require the first parameter of a metaclass to be
"cls". Older versions want "mcs". There's no way to support both by changing the
code, so the configuration file of pylint is changed instead, to have the
current codebase work with both versions.

The test support code is mainly written from scratch, so in order to
ensure to keep the code quality high, enable pylint and PEP8 checks
for it.

Due to some specialities of the test code, a dedicate pylintrc-test file
is created which configures pylint for test code.

Those differences include:
 - lowercase functions are allowed if the first word is test, assert or
   main
 - lowercase methods are allowed if the first word(s) is test, assert,
   runTests, setUp or tearDown
 - R0201 (method could be a function) is disabled

The longest Python files we still have are around 4200 lines long. In
order to prevent future growth, limit the maximum file length (checked
by pylint) to 4500 lines.

For the type system, we want a slightly relaxed rule for constant
naming, so we update the pylint rule. But the old _TPInt and _TNEString
were not clear enough, so we expand them.

While we'll need to update the source files too, at least this change
makes pylint 0.21 not fail on the current source tree.

There seems to be a bug in pylint relating to W0201 (“Attribute '%r'
defined outside __init__”) being re-enabled by simple comments and not
being able to be disabled again.

Until that is fixed, we disable this warning.

R0922, “Abstract class is only referenced 1 times”, cannot be disabled
in the source code, and thus
lib/http/auth.py:HttpServerRequestAuthentication gives this warning
(it's actually also referenced from the tests, but we do not include
them).

Therefore we need to disable it at pylintrc level.

This is a very slow checker, estimated to be O(n²) by its author; so
using it all the time is not good. It can be re-enabled on the command
line via “--disable-checker=”.

We don't get any useful out of this - a git grep is as effective, and
these only pollute the pylint output.

Since the current pylintrc is in now way good for our style, we update
it:

- remove docstring checks, since we have too many cases where a
  docstring doesn't make sense
- relax naming rules to cover more alternatives (but not break the
  naming rules)
- increase many of the limits
