* [BREAK] add possibility to download and use multiply

Translation files, configurable with Acquire::Translation (Closes: #444222, #448216, #550564) * Ignore :qualifiers after package name in build dependencies for now as long we don't understand them (Closes: #558103) * apt-pkg/contrib/mmap.{cc,h}: - extend it to have a growable flag - unused now but maybe... * apt-pkg/pkgcache.h: - use long instead of short for {Ver,Desc}File size, patch from Víctor Manuel Jáquez Leal, thanks! (Closes: #538917) * apt-pkg/acquire-item.cc: - allow also to skip the last patch if target is reached, thanks Bernhard R. Link! (Closes: #545699) * ftparchive/writer.{cc,h}: - add APT::FTPArchive::AlwaysStat to disable the too aggressive caching if versions are build multiply times (not recommend) Patch by Christoph Goehre, thanks! (Closes: #463260)
