[PATCH v1 0/3] Add _FORTIFY_SOURCE support for inet_ntop

[Frédéric Bérat]

Hi,

This patchset enables inet_ntop fortification.

This builds with and without fortification, and all checks passed on x86_64.

Fred.

Changes since v0:
 - Rebased on master
 - Fixed extra new line in "Prepare inet_ntop to be fortified", and amended the
   commit message.
 - Fixed missing end of comment in "Add missing guards in include/arpa/inet.h"
 - In "Add _FORTIFY_SOURCE support for inet_ntop":
   - Fixed commit message referring to the manual.
   - Initializing inputs in the inet+ntop fortify test.
   - Extended the comment around inet-fortified-decl.h inclusion to explain why
     it is needed unguarded there.
   - Reverted spurious white space change
   - Add missing spaces before '(' in inet-fortified.h
