Brian Anderson d36a8f3f9c collections: Move push/pop to MutableSeq 
Implement for Vec, DList, RingBuf. Add MutableSeq to the prelude.

Since the collections traits are in the prelude most consumers of
these methods will continue to work without change.

/// Represents a Windows path
// Notes for Windows path impl:
// The MAX_PATH is 260, but 253 is the practical limit due to some API bugs
// See http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247.aspx for good information
// about windows paths.
// That same page puts a bunch of restrictions on allowed characters in a path.
// `\foo.txt` means "relative to current drive", but will not be considered to be absolute here
// as `∃P | P.join("\foo.txt") != "\foo.txt"`.
// `C:` is interesting, that means "the current directory on drive C".
// Long absolute paths need to have \\?\ prefix (or, for UNC, \\?\UNC\). I think that can be
// ignored for now, though, and only added in a hypothetical .to_pwstr() function.
// However, if a path is parsed that has \\?\, this needs to be preserved as it disables the
// processing of "." and ".." components and / as a separator.
// Experimentally, \\?\foo is not the same thing as \foo.
// Also, \\foo is not valid either (certainly not equivalent to \foo).
// Similarly, C:\\Users is not equivalent to C:\Users, although C:\Users\\foo is equivalent
// to C:\Users\foo. In fact the command prompt treats C:\\foo\bar as UNC path. But it might be
// best to just ignore that and normalize it to C:\foo\bar.
//
// Based on all this, I think the right approach is to do the following:
// * Require valid utf-8 paths. Windows API may use WCHARs, but we don't, and utf-8 is convertible
// to UTF-16 anyway (though does Windows use UTF-16 or UCS-2? Not sure).
// * Parse the prefixes \\?\UNC\, \\?\, and \\.\ explicitly.
// * If \\?\UNC\, treat following two path components as server\share. Don't error for missing
// server\share.
// * If \\?\, parse disk from following component, if present. Don't error for missing disk.
// * If \\.\, treat rest of path as just regular components. I don't know how . and .. are handled
// here, they probably aren't, but I'm not going to worry about that.
// * Else if starts with \\, treat following two components as server\share. Don't error for missing
// server\share.
// * Otherwise, attempt to parse drive from start of path.
//
// The only error condition imposed here is valid utf-8. All other invalid paths are simply
// preserved by the data structure; let the Windows API error out on them.
