[PATCH v3 04/12] parsemail: Extract building the list of mail references

[Stephen Finucane]

From: Damien Lespiau <damien.lespiau at intel.com>

We'll need to figure out whether the mail we are parsing is the root of
the thread to automatically build series, and we'll need the list of
references for that.
