This requires linking to the TBB library on Linux, where libstdc++
and libc++ don't provide an implementation.

================
In this first stage, the plugins to be sorted are parsed and their record IDs
(which are FormIDs for all games apart from Morrowind) are stored. Parsing is
multithreaded by dividing the plugins into buckets with roughly equal total file
sizes, and loading each bucket's plugins in a separate thread. The number of
buckets created is equal to the number of concurrent threads that are
hardware-supported (e.g. a dual-core CPU without hyperthreading may report that
it supports two threads).
When parsing plugins, all subrecords are skipped over for efficiency, apart from
the subrecords of the ``TES4`` header record.

Loading plugin data also involves loading any metadata that the plugin may have
in the masterlist and userlist.
