byLine and byLineCopy should be safe

std.stdio.File.byLine:

Should be @safe as the internally used buffer is GC allocated, thus unexpected mutation of an escaped line is possible, but cannot cause a memory corruption.

@safe function 'foo' cannot call @system function 'std.stdio.File.byLine!(char, char).byLine'
@safe function 'foo' cannot call @system destructor 'std.stdio.File.ByLine!(char, char).ByLine.~this'

---

std.stdio.File.byLineCopy:

obviously

@safe function 'foo' cannot call @system function 'std.stdio.File.byLineCopy!(char, immutable(char)).byLineCopy'
@safe function 'foo' cannot call @system destructor 'std.stdio.File.ByLineCopy!(immutable(char), char).ByLineCopy.~this'

I think #9035 might take care of this, but it still is WIP and lacks testcases is only a small step in that direction AFAICT.
