Move name memoization out of variables
memoizeFullName was added to variables, rules and pools as an
optimization to prevent recomputing the full name repeatedly,
but the storage of variables, rules and pools are generally global
and not tied to the Context. When running multiple tests in
parallel there will be multiple Context objects all trying to
update the memoized names on the global variables, causing a data
race.
Package names were previously memoized via a pkgNames map stored
on the Context. Expand pkgNames to a nameTracker object that
contains maps for packages, variables, rules and pools, and replace
calls to fullName with calls through nameTracker.
Test: context_test.go
