build: rename all symbols to use sysprof_ as prefix
As we gain in usage, we need to be more careful about using a prefix that will not collide with other symbols. So version 3 of our ABI will change to using Sysprof/SYSPROF/sysprof as the various prefixes. The soname/api version bump will happen later on this branch so that things are easier to test up until then.
