821ec9843c Fix win32 build
The types size_t and ssize_t are defined on Windows (in MSYS2), so there
is no need to typedef SIZE_T and SSIZE_T.

Exit code is "unsigned long" both on Windows 32 and 64 bits.

See <https://github.com/Genymobile/scrcpy/issues/46#issuecomment-373603596>.

1038bad385 Make it work over tcpip
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>

To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.

Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.

Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.

Fixes <https://github.com/Genymobile/scrcpy/issues/5>.

221a7d0826 Clean up the server from temporary folder
The server is copied to /data/local/tmp/scrcpy-server.jar and executed
on the device.

As soon as we are connected, we can unlink (rm) it from /data/local/tmp,
to keep the device clean.

9b056f5091 Replace SDL_net by custom implementation
SDL_net is not very suitable for scrcpy.

For example, SDLNet_TCP_Accept() is non-blocking, so we have to wrap it
by calling many SDL_Net-specific functions to make it blocking.

But above all, SDLNet_TCP_Open() is a server socket only when no IP is
provided; otherwise, it's a client socket. Therefore, it is not possible
to create a server socket bound to localhost, so it accepts connections
from anywhere.

This is a problem for scrcpy, because on start, the application listens
for nearly 1 second until it accepts the first connection, supposedly
from the device. If someone on the local network manages to connect to
the server socket first, then they can stream arbitrary H.264 video.
This may be troublesome, for example during a public presentation ;-)

Provide our own simplified API (net.h) instead, implemented for the
different platforms.

28c5cc030b Move server-related code to server.c
The file server.c already existed, but exposed a low-level API. Make it
higher-level, so that scrcpy.c does not handle server details directly.

Only include SDL_stdinc.h for SDL_bool, not the whole SDL.h.
