* 'httpclient' of git://github.com/whoopdedo/dokuwiki:
  Adjust unit test to reflect desired behavior of max_bodysize
  Avoid timeout when content-length is 0
  Limit size of reads when max_bodysize is set or content-length is present
  Skip over chunk extensions that nobody uses because RFC2616 says so
  HTTPClient will read up to max_bodysize if it can
  Validate the size of a chunk before reading from the socket
  Efficiently wait on sockets
  HTTP headers are already parsed, there is no need for regexp
  Utility function for writing to a socket
  Unit test for HTTPClient chunked encoding
  Utility functions for reading from a socket.
  Raise an exception on socket errors.
  Correct handling of chunked transfer encoding. (FS#2535)
  Avoid strict warnings about unset array keys.
  Reference static variable through 'self::' as you're supposed to.
