Stream: preread phase.

In this phase, head of a stream is read and analysed before proceeding to the
content phase.  Amount of data read is controlled by the module implementing
the phase, but not more than defined by the "preread_buffer_size" directive.
The time spent on processing preread is controlled by the "preread_timeout"
directive.

The typical preread phase module will parse the beginning of a stream and set
variable that may be used by the content phase, for example to make routing
decision.
