cacheset: Fix -Wdeprecated-copy warnings

2020-02-26T17:59:39Z

Remove the operator= from Container_iterator, as it was basically just the default anyway, and add copy constructors to *Interface that match their operator=. Tried adding copy constructor to Container_iterator, but that only made things worse.

Fix various compiler warnings

Parse records including empty tag names correctly

2020-02-26T17:12:18Z

No sensible file should include these, but even insensible files do not gain unfair advantages with it as this parser does not deal with security critical files before they haven't passed other checks like signatures or hashsums. The problem is that the parser accepts and parses empty tag names correctly, but does not store the data parsed which will effect later passes over the data resulting e.g. in the following tag containing the name and value of the previous (empty) tag, its own tagname and its own value or a crash due to an attempt to access invalid memory depending on who passes over the data and what is done with it. This commit fixes both, the incidient of the crash reported by Anatoly Trosinenko who reproduced it via apt-sortpkgs: | $ cat /tmp/Packages-null | 0: | PACKAGE:0 | | : | PACKAGE: | | PACKAGE:: | $ apt-sortpkgs /tmp/Packages-null and the deeper parsing issue shown by the included testcase.
