Add <initializer_list> to stdc++.h and ruminations on aggregation headers

[Ed Smith-Rowland <3dw4rd at verizon dot net>]

All,

I was looking at Bjarne Stroustrups proposal n2905.pdf for aggregation 
headers and looking at our own in precomp.

His std-all is basically our stdc++.h except that the latter doesn't 
have <initializer_list>.  I know it really is in there but I thought it 
might be nice to put it in there explicitly for forms sake.  See the 
patch and changelog.

Also attached are simple implementations of std-all and std-checked to 
play with and some toy drivers.

In particular, is there anything we could add to std-checked that 
libstdc++ checks?
Maybe if someone, say, includes <vector> and then includes <std-checked> 
we should yell because (unless they threw the debug flag on the command 
line) they won't get the range checking.

We could add an ext-all.

Naturally, these would be candidates for user pch.

Of course these aggregation headers are not in the std yet ;-).  These 
are just to think about.

But the patchlet adding <initializer_list> to stdc++.h is bootstrapped 
and regtested on powerpc-apple-darwin7.9.0.

// ./bin/bin/g++ -std=c++0x -o std_checked std_checked.cpp

// LD_LIBRARY_PATH=bin/lib64 ./std_checked

#include "std-checked"

int
main( void )
{
    std::vector<int> v(5);
    std::cout << "v[5] = " << v[5] << std::endl;
    return 0;
}

// ./bin/bin/g++ -std=c++0x -o std_all std_all.cpp

#include "std-all"

int
main( void )
{
    std::vector<int> v(5);
    std::cout << "v[5] = " << v[5] << std::endl;
    return 0;
}
