MINOR: init: extract args parsing to their own function

The cmdline argument parsing was performed quite late, which prevents
from retrieving elements that can be used to initialize the pools and
certain sensitive areas. The goal is to improve this by parsing command
line arguments right after the early init stage. This is possible
because the cmdline parser already does very little beyond retrieving
config elements that are used later.

Doing so requires to move the parser code to a separate function and
to externalize a few variables out of the function as they're used
later in the boot process, in the original function.

This patch creates init_args() but doesn't move it upfront yet, it's
still executed just before init(), which essentially corresponds to
what was done before (only the trash buffers, ACLs and Lua were
initialized earlier and are not needed for this).

The rest is not modified and as expected no change is observed.

Note that the diff doesn't to justice to the change as it makes it
look like the early init() code was moved to a new function after
the function was renamed, while in fact it's clearly the parser
itself which moved.
