* libhideip version 0.2
Renamed PATH_SEP to LHIP_PATH_SEP to avoid conflicts.

2008-12-23
* libhideip version 0.1
Intercepting the following functions: gethostbyaddr, gethostbyaddr_r,
gethostbyname, gethostbyname_r, gethostbyname2, gethostbyname2_r,
gethostent, gethostent_r, getipnodebyaddr, getipnodebyname,
getifaddrs, getnameinfo, getaddrinfo, socket, recvmsg, sendmsg,
gethostname (lhip_net.c), execve, system (lhip_exec.c), ioctl
(lhip_ioctl.c), uname (lhip_uname.c), fopen64, freopen64, open64,
openat64, fopen, freopen, open, openat (lhip_opens.c).
All these functions could either directly or indirectly (opening
files) lead to discovering the local public IP address (not the
"127.0.0.1" address, but the external addresses of the machine's
network interfaces). Support for banning programs is added - the
banned programs get the original results, not hidden.
Compiles on OpenBSD.
