getusershell: Work around musl bugs. Reported by Bruno Haible in <https://lists.gnu.org/archive/html/bug-gnulib/2024-05/msg00261.html>. * doc/glibc-functions/getusershell.texi: Mention the musl bug. * lib/unistd.in.h (getusershell, setusershell, endusershell): Allow the functions to be declared with the rpl_ prefix. * m4/getusershell.m4 (gl_FUNC_GETUSERSHELL): Prepare functions to be replaced on musl systems. (gl_PREREQ_GETUSERSHELL): New macro. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize REPLACE_GETUSERSHELL. * modules/getusershell (Depends-on): Update module conditions to account for the function being available but replaced by Gnulib. (configure.ac): Likewise. Invoke gl_PREREQ_GETUSERSHELL.
