content_set_buffer now takes a uint8_t* instead of a void* so it can be correctly wrapped automatically

Add null character at the end of the key when storing it in a LinphoneContent (to prevent invalid reads).

Fix const string return values so that wrapper generators know that these strings do not need to be dealloced.

A normal LinphoneContent object will now copy the data from the given buffer when calling linphone_content_set_buffer().
However LinphoneContent objects converted from LinphoneContentPrivate structures do not own its data fields.
