New subprocess implementation and multiple fixes Changes: * Running processes now uses new implementation that is more resilient against stucked programs and reports output as soon as it happens * opkg-wrapper: added possibility to ignore custom feeds * pkgupdate: consider set root directory when looking for default entry config * Add additional reported states to pkgupdate Cleanups: * dropped base.lua as it is part of distribution not updater it self now Fixes: * Fix l10n and list settings error when there is no relevant section in uci config * Fix root directory to be used as absolute path because otherwise use of this variable broke with changed directory * opkg-wrapper, localrepo: take in consideration root directory * Fixed some warning that were failing tests
