Summary: Currently, the Scudo Hardened Allocator only gets its flags via the SCUDO_OPTIONS environment variable. With this patch, we offer the opportunity for programs to define their own options via __scudo_default_options() which behaves like __asan_default_options() (weak symbol). A relevant test has been added as well, and the documentation updated accordingly. I also used this patch as an opportunity to rename a few variables to comply with the LLVM naming scheme, and replaced a use of Report with dieWithMessage for consistency (and to avoid a callback).
