[patch] Unqualified calls to std::copy() in bits/vector.tcc

[Jonathan Wakely <cow at compsoc dot man dot ac dot uk>]

Our std::vector contains a few unqualified calls to std::copy().

This causes problems for Boost's Meta-Programming Library (where "copy"
is a functor) due to 3.4's improved ADL (see core DR 218, PR 17365 and
PR 17045 for related cases).

This isn't technically a regression, since these calls were always
unqualified until 3.4.0 but qualifications should probably have been
added to these calls along with all the others. It could be argued that
since previous versions didn't have correct ADL no conflicts arose, so
this is a regression.

Tested on i386/FreeBSD. Is this OK for mainline? and 3.4?

	include/bits/vector.tcc: Qualify all calls to std::copy().

I'm going on holiday so won't be able to commit this myself after today.
If it's approved then someone else might want to commit it sooner.

I think there are also a couple of unqualified calls in rope (lines 188
and 215) but I won't have time to check that properly before I go away.
