This fixes tons of warnings with clang from a recent xcode version on
macOS (and possibly other systems) complaining that an instantiation
of _singleton is required but no definition is available.
If the themepath was defined but the wwwroot.zip file was not in
that path, looking for it failed as it never reached the part of the
code using SearchMan to look for it.
This means that when using SDL 1.2 we use SDL_net 1.2, but when
using SDL 2 we now use SLD_net 2 as well. Both versions work
properly and there is not code change needed in ScummVM.
This change is because SDL_net depends on SDL, and using
SDL_net 1.2 with SDL 2 means we can end up needing to link with
both the SDL and SDL2 libraries.
Reader now reads headers into stream, and some checks are added there
and in UploadFileClientHandler, so if headers are too long, they are
treated as bad request.
Now if there is no "rootpath" specified, it's not even listed by
FilesPageHandler and ListAjaxHandler. And, of course, not available to
use anywhere else.
Paths containing '../' are forbidden to use in Files Manager. There is
also a special inner black list of paths which are not used and a check
that specified path is under "savepath" or "rootpath" (from "cloud"
domain).
StorageWizardDialog now runs LocalWebserver in "minimal mode" for
security reasons. In this mode server uses only those handlers which
state to support it.
There are two handlers which support minimal mode: IndexPageHandler
(which handles `code` requests needed by StorageWizardDialog) and
ResourceHandler (which provides inner resources like `style.css` or
`logo.png` from `wwwroot.zip` archive).
It now redirects user on success not only when file was the last field
in the content, but also when it was uploaded already and Handler worked
further to search for more files.
It now hides code fields not just when built with SDL_Net, but also when
LocalWebserver's using default port.
So that's why NETWORKING_LOCALWEBSERVER_ENABLE_PORT_OVERRIDE is defined
in localwebserver.h now.
It's enabled only when NETWORKING_LOCALWEBSERVER_ENABLE_PORT_OVERRIDE is
defined.
It's not defined, because override means we have to reconfigure our
redirect links somehow to use the override port.
