Experimental support for instaling on Mavericks.  Code unchanged, only the installer checks are lifted.
Fix and enhanced generation of version info files.  Now includes also
the build time and a the actual version number.

Added version information to all binaries.  The version strings are
computed once and then inserted into each build product using the
pre-existing versioning infrastructure.
Added version check to prevent user land tools from one implementation
talking to an incompatible kernel space part.

This introduces two new ioctl() command and the necessary changes in
the kernel resident ioctl() handler.  The libzfs is changed to automatically
attempt a version check when opening the control device.
Disabled verbose compiler output.
Changed identifier template from Alblue's (valid) ID to a new invalid one.
Updated file list and fixed some wrong default permissions.
Updated installer texts to list Maverick as supported.
Added back man pages missing from last installer.
Added new install targets:
 - install-sys : install kext into sytem folders
 - install-sys-load : try to load the kext and record the load address for debugging
Added printing of kext version to console at load time.
Disabled debug info in generated package.
