Brooks Davis 1235d276b7 lib{c,sys}: stop exposing errno symbol ... Officially since C11 (and in reality FreeBSD since 3.0 with commit 1b46cb523d) errno has been defined to be a macro. Rename the symbol to __libsys_errno and move it to FBSDprivate_1.0 and confine it entierly to libsys for use by libthr. Add a FBSD_1.0 compat symbol for existing binaries that were incorrectly linked to the errno symbol during libc.so.7's lifetime. This deliberately breaks linking software that directly links to errno. Such software is broken and will fail in surprising ways if it becomes threaded (e.g., if it triggers loading of a pam or nss module that uses threads.)
