Fix compiler-rt build on FreeBSD 10.1

[emaste]

Summary

We have to #define _WANT_RTENTRY to get struct rtentry, and add headers that it depends on.

[emaste]

SIOCADDRT and SIOCDELRT also do not exist in FreeBSD 10.1

    Garbage collect long time obsoleted (or never used) stuff from routing API.

Adding eugenis just in case. The change looks fine to me.

lib/sanitizer_common/sanitizer_platform_limits_posix.cc

Could you move this below

#if SANITIZER_LINUX || SANITIZER_FREEBSD || SANITIZER_MAC

line?

lib/sanitizer_common/sanitizer_platform_limits_posix.cc

Nest it inside the block at line 23? Sure.

LGTM
