C++ Network Library Code

Added copyright for Boost compliance and removed unnecessary include.

Fixing http_test_server.hpp to remove double patching result (oops).
Fixing http_test_server.hpp to not define the server_child member variable inline.
Fixing signedness comparison bug(s) in localhost_tests.cpp that show up with GCC.

Patch from Kim Grasman to mark expected failures from localhost_tests.cpp and factoring out http_test_server implementation to its own file.

1 line commit that allows the cgi app to return the headers requested by a client.

Note: This also suffers from bugs in implementation. Notably, the use of a default content-type header for the request.

Fixing bug which causes infinite loop in processing user-provided headers in http::client::create_request.

Changes:
- http/impl/request.hpp: moving uri parsing out of constructor and into a 'uri' member function of the request object
- http/client.hpp: support for resolved endpoint caching and HTTP 300..307 redirection
- http/response.hpp: adding proper copy constructor
- http_1_0_test.cpp: adding tests for resolved endpoint caching and 300->307 redirection

First commit of MIME header. Not even tested to compile (sorry!). For everyone's comments and suggestions.
