cleanup request size limiting for TeeInput users

WAvoid mucking with Unicorn::TeeInput, since other apps may
depend on that class, so we subclass it as Rainbows::TeeInput
and modify as necessary in worker processes.

For Revactor, remove the special-cased
Rainbows::Revactor::TeeInput class and instead emulate
readpartial for Revactor sockets instead.

+  # while providing rewindable semantics through a File/StringIO
+  # backing store.  On the first pass, the input is only read on demand
+  # so your Rack application can use input notification (upload progress
+  # and like).  This should fully conform to the Rack::InputWrapper
+  # specification on the public API.  This class is intended to be a
+  # strict interpretation of Rack::InputWrapper functionality and will
+  # not support any deviations from it.
