Subject: [PATCH 2/2] [httpc] Allow binary() header values in request/5

Fix a bug where using a binary() in a header value to request/5 would
cause the application to hang.  Now allow a binary() as a header
value.  Extend error checking of arguments to request/5 and be more
precise with returned errors when arguments have an invalid type.

* Add tests
  * Catch test problem earlier
  * Add new tests for header types and other arguments to request/5
  * Be more precise when checking the error returned

* Code
  * Abstract construction of header-value string for consistency
  * Make checking of headers values and arguments consistent and
    more precise.

* Update documentation
  * Correct types in documentation
  * Use http_string() instead of string() to avoid possible confusion
    due to using a well defined system wide type.
