libstdc++: Use only public basic_streambuf methods in std::advance overload
std::advance overload for istreambuf_iterator can be implemented using
basic_streambuf public pubseekoff method so that it doesn't have to be
basic_streambuf friend.
libstdc++-v3/ChangeLog:
* include/std/streambuf
(advance(istreambuf_iterator<>&, _Distance)): Remove friend
declaration.
* include/bits/streambuf_iterator.h
(advance(istreambuf_iterator<>&, _Distance)): Re-implement using
streambuf pubseekoff.
*
testsuite/25_algorithms/advance/istreambuf_iterators/char/3.cc: New
test.
Tested under Linux x86_64.
Ok to commit ?
