Bug#881860: transition: glibc 2.25

Severity: normal

Dear release team,

I would like to get a transition slot for glibc 2.25. It is available
in experimental for more than two months, and there is no known
regression. It is currently available in experimental and has been built
successfully on all official architectures. For the debian-ports
architectures the situation is not good as it this version has never
been built successfully on alpha and powerpcspe. That said that can be
fixed later and I don't think we should block the transition on that.

As the glibc is using symbol versioning, there is no soname change. That
said a few packages are using libc internal symbols and have to be
rebuilt for this transition:
 - apitrace
 - bro
 - dante
 - libnih
 - libnss-db
 - p11-kit
 - unscd

Here is the corresponding ben file:
  title = "glibc";
  is_affected = .depends ~ /libc[0-9.]* \(<</;
  is_good = .depends ~ /libc[0-9.]* \(<< 2.26\)/;
  is_bad = .depends ~ /libc[0-9.]* \(<< 2.25\)/;

In addition a few new symbols have been added that might prevent a few
other packages to migrate to testing until glibc migrates if they pick
up the new symbols. Most of them are libm.so to add support for
TS 18661-1:2014 math functions, but are currently unlikely to be picked
up by some packages. On the libc.so side, the explicit_bzero,
gententropy and getrandom might be picked up by a few packages.

Thanks for considering,
Aurelien
