Bug description:Built-in server truncates headers spanning over TCP packets
Description:
------------
The built-in server can truncate headers if they span over a TCP packet
boundary.
Internally, it uses MARK(header_value) (Sets header_value_mark to the
current pointer), then upon reaching the \r\n (in the next packet then,
same buffer), but the \r\n will end up being before the
header_value_mark pointer, thus ending up of never reading the part
before the \r\n in the second packet.
Test script:
---------------
Use a valid header and ensure it's send in two different TCP packets to
built-in server. Begin sending a header value in one packet and finish
it in another. Then dump the header value.
Expected result:
----------------
Header value should be complete.
Actual result:
--------------
The header value is being truncated at the exact packet boundary.
