namespace std in libstdc++

[Martin von Loewis <martin@mira.isdn.cs.tu-berlin.de>]

This patch adds 'namespace std' to several places in libstdc++. It is
only a minimal change:
- std is enabled for STL, which already provides this as a configuration
  option.
- std is added to stdexcept, like the exceptions used by the language
  runtime (e.g. std::bad_alloc).
- std qualification is added to places where it was missing.

With current egcs, these changes are not noticable unless g++ is
invoked with -fnew-abi. As this option suggests, enabling it really
results in binary incompatibility, as the mangling for std:: qualified
types will be different.

I'm aware that std scoping is missing in many more places, but I hope
that will be provided in the upcoming rewrite of libstdc++.

	* stdexcept: Conditionally wrap into namespace std.
	* stl/stl_config.h: Likewise, for gcc 2.8 or better.

	* stdexcepti.cc (__out_of_range, __length_error): Qualify standard
	exception classes with std::.

	* bastring.h: Qualify iterator templates with std::.
