Sometimes the textual error message returned by archive_error_string()
does not reveal enough useful information, add also the error code from
archive_errno().

Add where missing. Replace occurrences of Q_DECL_OVERRIDE macro,
building IFW requires a C++11 compatible compiler so the language
specifier is preferred.

This fixes losing executable bits of files in Zip archives when
extracted. Zip archives store file metadata in two ways, partial
metadata per-entry and full metadata at the end of archive. IFW's read
implementation previously did only streaming without support for seeking
archives, which is required to obtain full metadata - meaning the
partial metadata was used instead by libarchive's Zip reader. The
extracted entries between the two metadata types are not consistent.
This change also enables usage of archive formats that cannot be
accurately handled with a streaming model, like 7zip which needs to read
key data from the end of the file before reading file data from the
beginning.

libarchive is a multi-format archive and compression library
written in C and licensed under the new BSD license. Usage of
libarchive brings in support for additional archive formats
(in addition to 7z) with the installer framework, like zip and
tar, with several available compression methods like gzip, bzip2
and xz.
libarchive will coexist as a supported archive format handler
with the LZMA SDK currently used in the framework, which will
continue to be used for handling the 7-Zip file format.
This change introduces classes for handling archive operations
using both libraries, removes most calls to the old Lib7z facade
and migrates the code base to use the new handling methods.
