#### Description <!-- Describe your changes in detail --> Previously, to remove a parameter from a header it was needed to create a complex method on the configuration file for each header/parameter. This modification moves this complexity to the 'pv_headers' module.

Two new functions: * pvh_header_param_exists * pvh_remove_header_param

Both functions take as parameters the name of the header and the name of the parameter.

It returns '-1' if the combination header/parameter: - is not found (pvh_header_param_exists) - couldn't be removed (pvh_remove_header_param).

Examples (proxy configuration):

if (pvh_header_param_exists("Supported", "100rel")) { // "100rel" is present on the "Supported" header }

if (pvh_remove_header_param("Supported", "100rel")) { // "100rel" removed from header "Supported" } You can view, comment on, or merge this pull request online at:
