Fix httpd config option 'erl_script_nocache'

This fixes the usage of the httpd configuration option
'erl_script_nocache', which got ignored before.

Attention: Before, the option 'script_nocache' also changed the
behavior for mod_esi, now it only affects mod_cgi.
inets: added simple testcase for option erl_script_nocache
Test nocache option of mod_cgi and mod_esi

Tests that the nocache options work and can be used independently from
each other. This was broken before c8ef69c.

Fix {stream, {self, once}} in httpc

Previously the only difference between {stream, self} and {stream,
{self, once}} was an extra Pid in the stream_start message due to a
bug in httpc_handler. It was immediately sending a bunch of messages
till the end instead of waiting for httpc:stream_next/1 being called.
Remove http_chunk:decode/4 as it is no longer used

http_chunk:decode/4, the side-effecting chunk decoder, was only used
by httpc_handler:handle_http_body/2 but now it's completely unused.

Conflicts:

	lib/inets/src/http_client/httpc_handler.erl
inets: httpc make httpc_cancel_request/[1,2] asynchronous

inets: httpc - Remove dead error handling code

Some error handling is only relevant for functions that
end up in gen_server:call and not in gen_server:cast.
