kernel-symbol: delay symbol filtering until lookup
...
We don't want to avoid adding the symbols to the index table, or we will
get the wrong addresses.
So instead, add them, and then ignore the symbols upon lookup.

We should be betting a context change as part of the stack, so ignore it
if we didn't get a user context.

kallsyms: make SpKallsyms more testable
...
This allows us to pass in the file to read from, and adds a quick test
case to view the parsed output. It also fixes a base-10 vs base-16
mistake in parsing addresses.

elf: only resolve addresses in none/user address context
...
This ensures that we only try to resolve addresses for ELFs when we know
we're inside of the userspace address context.

We only want to resolve a symbol if we're inside the kernel context.
Otherwise, it wont be accurate.

We might need access to the address context when resolving symbols so that
we know if the address range applies to us.

lib: query /proc/kallsyms and/or daemon for symbols
...
If we have a system where we can read kallsyms without elevated
privilledges do that. Otherwise, query the sysprod daemon to get the
available kernel symbols.
