stream_context_create silently ignores invalid options

[aliber4079]

Description

for example
$context=stream_context_create([ 'ssl' => [ 'verify_peername' => FALSE, ] ]);
the property verify_peername should be verify_peer_name but $context is not FALSE and no error is reported

I think it's reasonable feature request. The question is if it should be deprecation (next minor) and then error (next major) or just warning or notice...

[Girgias]

The standard approach would be to add a warning and promote it to throwing a ValueError at a later date.
