Brad King 6db713c07f Remove use of include <cmsys/ios/*> and cmsys_ios::*
We no longer need this compatibility layer for the compilers we support.

Roman Donchenko edae40239e cmArchiveWrite: do not store sparse files when using standard tar formats
Sparse files in tars are a GNU extension that libarchive will use if it
detects holes in the input file, even when using the standard pax/paxr
formats. Not all tar implementations can handle sparse files; in particular,
the internal implementation dpkg uses to extract packages can't. To
maximize archive portability, turn this feature off by clearing the
sparseness information from archive entries.

Nils Gladitz d2cc580704 cmake: Teach "-E tar" command a "--format=" option
Allows specifying a libarchive defined archive format currently restricted to
7zip, gnutar, pax, paxr and zip.

The default is "paxr" (pax restricted).

Brad King 0f870234fe Merge branch 'backport-no-global-setlocale' into no-global-setlocale
Resolve conflict in Source/CMakeLists.txt by taking both changes.

Brad King cd408d93fd Add setlocale() calls around use of libarchive APIs (#14934, #15377)
The libarchive APIs use nl_langinfo(CODESET) for iconv so they need the
locale to be set for LC_CTYPE.  However, the rest of CMake does not
define any behavior for non-ASCII character classification/conversion so
we do not want to setlocale() globally.  Add a RAII class to save, set,
and restore the locale around calls to libarchive APIs.

Brad King 3a60c899fc cmake: Teach "-E tar" command a "--mtime=" option
Add an option to set the mtime of entries in a tarball so that one can
create a tarball with a consistent content hash (e.g. MD5) for a given
set of files regardless of their current timestamps on disk.  This will
be useful for submission of tarballs to CDash, which tracks content
hashes to avoid duplication.

Brad King 90f9c42732 cmake: Teach "-E tar" to report file name on failure to read from disk
The libarchive-provided error message does not always include the file
name, so add it to the message ourselves to ensure users know which file
fails.

Clinton Stimpson 71c981a213 Encoding: Fix potential encoding issues with libarchive on Windows.
Because the 8bit string encoding in libarchive can be different than
the 8bit string encoding in CMake, change to call the wide version
of libarchive functions.  They are different if CMake is configured
to use UTF-8 as the internal encoding.

Create helper functions for some libarchive calls to use wstring
internally on platforms supporting it.

If archive_error_string returns NULL, use a placeholder string instead
of crashing.

Clinton Stimpson 5730710c86 Use cmsys::[io]fstream instead of cmsys_ios::[io]fstream.
Also use SystemTools::Fopen() instead of fopen().
This is to eventually support utf-8 filenames.

Brad King a34015d356 cmArchiveWrite: Clear fflags from archive entries
When reading archive entries from disk strip any "fflags" entry headers
that may have been loaded from the filesystem when libarchive is built
with HAVE_STRUCT_STAT_ST_FLAGS (struct stat has 'st_flags').  The local
filesystem flags are not useful for distribution.  Furthermore, GNU tar
does not understand the "SCHILY.fflags" extended header used to store
the flags in the archive.  Use the approach from commit e8558efa
(cmArchiveWrite: Clear xattr and acl from entries, 2011-04-07) to remove
the flags and avoid producing the non-portable extended header.

Eric NOULARD 768cf91831 Do not add the content of a file if it's a symlink.
This wasn't necessary for TAR-like (TGZ, TBZ2, etc...) archive
because for those the size was 0. Either there is an error in
upstream libarchive concerning the size or we should not rely
on size of the entry for adding content.

Johan Björk d78bdb2783 CMake: Write symlinks to directories as files in archives (#12284)
Do not recurse through directory symlinks when adding files.

Recursing through directory symlinks will generate broken archives,
i.e., they will look something like this:
  foo -> bar/bar
  foo/Info <- Shouldn't be in archive.
  bar/bar
  bar/bar/Info

Brad King e8558efa01 cmArchiveWrite: Clear xattr and acl from entries (#11958)
When reading archive entries from disk strip any xattr and acl entry
headers that may have been loaded from the filesystem (e.g. selinux).
These fields are only useful for backup tools and not for packaging and
distribution of software.  Furthermore, the GNU tar 1.15.1 on at least
one Linux distribution treats unknown entry headers as an error rather
than a warning.  Therefore avoiding such fields is necessary for archive
portability.

Eric NOULARD 1a3ad5c615 Add XZ compress support to libarchive-wrapper
This is not needed but it does not cost much to do it for all
potentially supported format in libarchive. XZ and LZMA are not
builtin libarchive and require external lib but if
CMAKE_USE_SYSTEM_LIBARCHIVE is ON then we may get it for free.

Eric NOULARD b50c15915a Add ZIP archive format and LZMA compress support to libarchive-wrapper
This will be needed to use cmArchiveWrire in cmCPackArchiveGenerator
with the same feature set as before. Note that adding zip
support to libarchive-wrapper would also makes it easy to add
a new -E zip command to cmake commands.

Brad King 4663356079 cmArchiveWrite: Fix signed/unsigned again
Some stream libraries return size_t from gcount() and some return
ssize_t.  Add an explicit cast to ios::streamsize for its return value.
Also refactor use of nnext to reduce the use of casts.

Brad King aef672311a cmArchiveWrite: Fix signed/unsigned compare/convert
The libarchive interface accepts size_t but returns ssize_t.  The std
streams interface wants streamsize, which is typically ssize_t.  Since
no one type for our variable matches without conversions, make the
conversions explicit to avoid -Wsign-conversion and -Wsign-compare
warnings.
