Adds a modified options parser (shamefully pulled from Scudo, which shamefully pulled it from sanitizer-common) to GWP-ASan. This allows customers (Android) to parse options strings in a common way. Depends on D94117. AOSP side of these patches is staged at: - sepolicy (sysprops should only be settable by the shell, in both root and unrooted conditions): https://android-review.googlesource.com/c/platform/system/sepolicy/+/1517238 - zygote updates: https://android-review.googlesource.com/c/platform/frameworks/base/+/1515009 - bionic changes to add `gwp_asan.<process_name>` system property, and GWP_ASAN_OPTIONS environment variable: https://android-review.googlesource.com/c/platform/bionic/+/1514989 Reviewed By: eugenis Differential Revision: https://reviews.llvm.org/D92696
