[Mono-dev] mono_path_canonicalize strips \\ from network paths on Windows

Some of our customers noticed that our Windows games don't run if
launched from network shares (e.g. \\somecomputer\path\game.exe).
Turns out AppDomain.CreateDomain throws exception when assemblies are
referenced via network path.

When debugging, I noticed that image open functions turn paths like
'\\somecomputer\path' into '\somecomputer\path' (turns double
backslash into a single one). mono_path_canonicalize does this.

In our case, changing this:
	if (dest != lastpos) {
		strcpy (dest, lastpos);
at the end of mono_path_canonicalize into this:
	if (dest != lastpos) {
		/* on Windows, do not strip '\\' from the beginning of network paths */
		#if defined (PLATFORM_WIN32)
		if( dest && dest[0] == G_DIR_SEPARATOR && lastpos && lastpos[0] == 0 )
			strcpy (dest, lastpos);
fixes the issue and makes everything work on network shares.

But as you can see from the code, I obviously don't know what I'm
doing and the same effect can probably be achieved much more
