Avoid reading pass the end of the source buffer when it is not NUL terminated. If this buffer is adjacent to an unmapped page or a version of C with bounds checked is used this may result in a crash. PR: 206178 Submitted by: Alexander Cherepanov

Fix strcasecmp_l() and strncasecmp_l() POSIX 2008 compliance. POSIX.1-2008 specifies that those two functions should be declared by including , not (the latter only has strcoll_l() and strxfrm_l()): http://pubs.opengroup.org/onlinepubs/9699919799/functions/strcasecmp.html Bump __FreeBSD_version for ports that may be using the non-standard reference.

libc man pages: Remove reference to non-existent FreeBSD Security Architecture

libc: Always use our own copy of sys_errlist and sys_nerr (.so only).

2013-08-31T22:32:42Z

This ensures strerror() and friends continue to work correctly even if a (non-PIE) executable linked against an older libc imports sys_errlist (which causes sys_errlist to refer to the executable's copy with a size fixed when that executable was linked). The executable's use of sys_errlist remains broken because it uses the current value of sys_nerr and may access past the bounds of the array. Different from the message "Using sys_errlist from executables is not ABI-stable" on freebsd-arch, this change does not affect the static library. There seems no reason to prevent overriding the error messages in the static library.

Renumber clauses to reduce diffs to other versions
