This change makes the dependency on quoted optional
by adding a minimal urldecode function to cowboy.
A protocol option for setting the urldecoding function
has been added to the cowboy_http_protocol module.
The default value for this option is set to be
equivalent to the default settings for quoted.
{fun cowboy_http:urldecode/2, crash}
A note has been added in the README to document
how to use quoted instead of this function.
A field to store this option value has been added
to the state record in the cowboy_http_protocol
module and the http_req record in include/http.hrl
Functions that previously used quoted:from_url/1
has been updated to require an equivalent function
in addition to the previously required arguments.
This change removes a C compiler from the build
requirements of cowboy. It also removes the requirement
to cross compile the code if the target arch/OS
is different from the arch/OS used to build it.
