Subject: opkg_download: decode file:/ URLs
X-Git-Url: https://git.librecmc.org/?p=oweals%2Fopkg-lede.git;a=commitdiff_plain;h=3b417b9f41b4ceb5912d82f867dd5534e5675b5c

opkg_download: decode file:/ URLs

Opkg might receive percent-encoded file:/ URLs from various sources,
e.g. local package lists, user-supplied command line arguments etc.

In order to support such URLs, decode the path component before
trying to invoke file operations on it.
