Running autogen.sh will initialize a working directory if autoconf 2.50+ and
automake are installed.
Due to conflicts with glibc header files:
Renamed byteswap.h -> hbyteswp.h
Renamed features.h -> feature.h
Detect presence of linux/if_tun.h, and use IFF_* constants if available.
Check for presence of sqrtl. It does not exist (for example) on powerpc,
where sizeof(long double) == sizeof(double).
