4.15.0: Dubliner

Releasing shadow 4.15.0: Dubliner

• libshadow:
  • Use utmpx instead of utmp. This fixes a regression introduced in
    4.14.0.
  • Fix build error (parameter name omitted).
• Build system:
  • Link correctly with libdl.
  • Install pam configs for chpasswd(8) and newusers(8) when using
    ./configure --with-libpam --disable-account-tools-setuid.
  • Merge libshadow and libmisc into a single libshadow. This fixes
    problems in the linker, which were reported at least in Gentoo.
  • Fix build with musl libc.
  • Support out of tree builds
• useradd(8):
  • Set proper SELinux labels for def_usrtemplate
