[PATCH 0/1] MR366: loader: Refactor argv/envp/auxv management.

[Jinoh Kang (＠iamahuman)]

Collect scattered variables holding stack addresses (e.g. pargc, argv,
envp, auxv) in one place.

This facilitates modifying stack values (e.g. removing argv[0],
switching stacks due to address conflict with reserved regions) without
leaving pointer variables stale.
