[arch-projects] [dbscripts] [PATCH 1/2] db-move: Don't store filepaths as a string with whitespace splitting

[Eli Schwartz]

Use arrays via nameref, since makepkg does not support multidimensional
arrays, and assigning to/retrieving from an array variable with an
unknown name requires this.

Requires bash 4.3, requires that architectures never contain chars that
are invalid in a variable name -- which makepkg explicitly requires in
order to support architecture-dependent sources/dependencies, and also
incorporates into linting checks which forbid anything but [[:alnum:]_]
so that's all good.
