merge back from gnulib to glibc

[Bruno Haible]

Hi Paul,

After the changes in the glibc development model [1][2][3], the glibc
people are asking for a more active merge from gnulib back to glibc [4].

Apologies if you read libc-alpha regularly and already saw this.

It would be interesting to report all the glibc bugs that we have found
("grep glibc doc/posix-*/*.texi" reveals numerous issues.) It's a large
work. Is someone keeping a TODO / progress list for this? (config/srclist.txt
so far only deals with the modified source code files.)
