Removing "using" delclarations that import names from the STL library.

Removing "using" delclarations that import names from the STL library.

This is as per the the coding guidelines for blink, which disallows
importing names from the STL library through the "using" declarations.

Thanks for the cleanup, but please delete the extra blank lines from the top of
the file rather than just clearing the line.

The correct way to define customized versions of std::swap is to define them as
swap and then use "using std::swap".  Collection libraries like STL and WTF
should use swap unqualified. This way ADL gets the right version.  See for
example the first answer to
http://stackoverflow.com/questions/6380862/how-to-provide-a-swap-function-for...

So does the style guide ban the use of "using std::swap" too?  It looks like it.

unfortunate, since it's the correct way to do it.
