Subject: [RFC PATCH v2 0/2] ELF: Alternate program property parser

This series is an experimental reimplementation of ELF property parsing
(see NT_GNU_PROPERTY_TYPE_0, [1]) for the ELF loader.

This is intended for comparison / merging with [2] (or could replace it,
if people think this approach is better).

This supersedes RFC v1 [3].

For changes see the individual patches.
