Update to version 2.3.0
Note that this is (mostly) a security fix release.

Changes since last packaged version (2.2.3):
2.3.0
 - modified chroot_helper to parse the config file, to avoid arbitrary
   chroot() (and thus root compromise)
 - numerous documentation updates
 - fix for va_start()/va_end()-related segfault on 64-bit architecture
 - small bit of code cleanup
