[roll] Roll fuchsia [kernel][phys] Enable ubsan runtime for phys environments This allows the normal ubsan variant to be chosen by variant selection in phys environments, including phys32 and efi. When enabled, this supercedes ubsan-trap and provides a minimal ubsan runtime (via //src/lib/ubsan-custom, shared code also now used by the kernel proper's ubsan runtime). The extra checks enabled for kernel code in ubsan builds beyond `-fsanitize=undefined` are also enabled for ubsan builds in the phys environments. Other than those additional checks, selecting the ubsan variant for a phys program doesn't add increased safety / checking compared to the ubsan-trap configuration used in all other builds; but it makes the failure modes much more comprehensible. This comes at the cost of some additional code size in the paths taken only for crashes, and much more substantial additional data size in the instrumented phys binaries. The "kubsan" shortcut alias now applies ubsan to all the main phys code as well as other kernel code.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
