Add test of httplib.h split into .h + .cc (#1015)

Browse source 
In order to test the split version (.h + .cc via split.py):

- Added a test_split program in the test directory whose main purpose is
  to verify that it works to compile and link the test case code against
  the split httplib.h version.
- Moved types needed for test cases to the “header part” of httplib.h.
  Also added forward declarations of functions needed by test cases.
- Added an include_httplib.cc file which is linked together with test.cc
  to verify that inline keywords have not been forgotten.

The changes to httplib.h just move code around (or add forward
declarations), with one exception: detail::split and
detail::process_client_socket have been converted to non-template
functions (taking an std::function instead of using a type parameter for
the function) and forward-declared instead. This avoids having to move
the templates to the “header part”.
