glibc 2.23 --- Starting soft/slush freeze

[Adhemerval Zanella]

Hi all,

At stated in a previous message we are now in soft/slushy freeze mode. 
Please do not commit new features other than the ones already reviewed.
If your new feature still needs review and was not listed in the releases 
wiki as a blocker feature [2] it is unfortunately too late. Please defer 
to glibc 2.23 when it opens.

Documentation changes and bug fixes are OK.
