Shawn Webb fc4d195f59 HBSD: Revert "Add AT_USRSTACK{BASE, LIM} AT vectors, and ELF_BSDF_VMNOOVERCOMMIT flag" 
This reverts commit ff41239f58. The way
HardenedBSD calculates usrstack is at odds with how FreeBSD calculates
AT_USRSTACK{BASE, LIM}.

FreeBSD introduced AT_USRSTACK{BASE, LIM} in order to save a few
syscalls on libthr and rtld startup. While syscalls are expensive, I
believe it is acceptable for now.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
