I would like to provide a way to preview the effects of pathname edits,
but pattern selection has to happen against the unedited path, so it
seems that we have to show people the unedited path to help in
designing selection patterns.
understand which code paths aren't possible.
This commit eliminates 117 false positive bug reports of the form
"allocate memory; error out if pointer is NULL; use pointer".

Don't leak file descriptors in write_entry_backend if archive_write_header
returns ARCHIVE_FAILED.

since they are only tested for zero/nonzero; but it's arguably a bad
idea to set a {-1, 0} variable to 1 (as happens in this code).

In addition to a number of bug fixes and minor changes:
* --numeric-owner (ignore user/group names on create and extract)
* -S (sparsify files on extraction)
* -s (regex filename substitutions)
* Use new libarchive 'linkify' to get correct hardlink handling for
both old and new cpio formats
* Rework 'copy' test to be insensitive to readdir() filename ordering
Most of the credit for this work goes to Joerg Sonnenberger, who
has been duplicating features from NetBSD's 'pax' program.
hardlink table for two reasons: 1. If le->name is set to NULL, the
structure le won't be inserted into the table; 2. Even if le somehow
did manage to get into the table with le->name equal to NULL, we would
die when we dereferenced le->null before we could get to the point of
freeing the entry.
Remove the unnecessary "if (le->name != NULL)" test and just free the
pointer.

running 'tar ""' would print 'No memory' instead of the correct error
message, 'Must specify one of -c, -r, -t, -u, -x' if malloc is set to
System V mode (malloc(0) == NULL).
(in fact, there has never been any way for it to be NULL, going all the
way back to revision 1.1 of this file), so remove the check and
unconditionally free entry.

handling to bsdtar. When writing archives (including copying via the
@archive directive) a line is output to stderr indicating what is being
done (adding or copying), the path, and how far through the file we are;
extracting currently does not report progress within each file, but
this is likely to happen eventually.

Currently if any files are ignored, bsdtar will exit with a non-zero
exit status; this is likely to change in the future, but requires some
API changes in libarchive.

* --format can be used with -r or -u
* -o is a synonym for --format=ustar when used with -c, -r, or -u
Also, fix the erroneous sanity check that suppressed --format with -r or -u.
GNU tar changed -l to match SUSv2 a couple of years ago,
so bsdtar no longer needs to pander to this particular GNUism.
