Fix deprecations

v0.8.0: fix missing gc-roots (#169)

* fix missing gc-roots

since calling `pointer()` explicitly discards gc-rooting
need to ensure that there is a memory barrier that uses the value
after we know for certain we are done with the value

note that a better pattern is usually to use `Ref` to make gc-safe interior pointers

* fix v0.7 compatibility with macrocall __source__ argument

* fix v0.6 compatibility with JLD00 and JLDArchive tests

* make JLD00-formatted files readable on v0.6

* Rebase fixes

* Fix tests
