9cb14b5166 Inherit only specific handles on Windows
To be able to communicate with a child process via stdin, stdout and
stderr, the CreateProcess() parameter bInheritHandles must be set to
TRUE. But this causes *all* handles to be inherited, including sockets.

As a result, the server socket was inherited by the process running adb
to execute the server on the device, so it could not be closed properly,
causing other scrcpy instances to fail.

To fix the issue, use an extended API to explicitly set the HANDLEs to
inherit:

52cebe1597 Fix Windows sc_pipe function names
The implementation name was incorrect (it was harmless, because they are
not used on Windows).

eaf4afaad9 Add command execution with redirection
Expose command execution with pipes to stdin, stdout and stderr.

This will allow to read the result of adb commands.

30e619d37f Replace SDL_strdup() by strdup()
The functions SDL_malloc(), SDL_free() and SDL_strdup() were used only
because strdup() was not available everywhere.

Now that it is available, use the native version of these functions.

6a50231698 Expose a single process_wait()
There were two versions: process_wait() and process_wait_noclose().

Expose a single version with a flag (it was already implemented that way
internally).

b8edcf52b0 Simplify process_wait()
The function process_wait() returned a bool (true if the process
terminated successfully) and provided the exit code via an output
parameter exit_code.

But the returned value was always equivalent to exit_code == 0, so just
return the exit code instead.

d580ee30f1 Separate process wait and close
On Linux, waitpid() both waits for the process to terminate and reaps it
(closes its handle). On Windows, these actions are separated into
WaitForSingleObject() and CloseHandle().

Expose these actions separately, so that it is possible to send a signal
to a process while waiting for its termination without race condition.

This allows to wait for server termination normally, but kill the
process without race condition if it is not terminated after some delay.
