from the private archive_write structure and fix up all writers to use
the format fields in the base "archive" structure. This error made it
impossible to query the format after setting up a writer because the
write format was stored in an inaccessible place.
"file" is described by multiple "lines" each possibly containing
multiple "keywords." Incorporate some additions from Joerg Sonnenberger
to handle linked files and correctly deal with backing files on disk.

(including pathname, gname, uname) be stored in UTF-8. This usually
doesn't cause problems on FreeBSD because the "C" locale on FreeBSD
can convert any byte to Unicode/wchar_t and from there to UTF-8. In
other locales (including the "C" locale on Linux which is really
ASCII), you can get into trouble with pathnames that cannot be
converted to UTF-8.
Libarchive's pax writer truncated pathnames and other strings at the
first nonconvertible character. (ouch!) Other archivers have worked
around this by storing unconvertible pathnames as raw binary, a
practice which has been sanctioned by the Austin group. However,
libarchive's pax reader would segfault reading headers that weren't
proper UTF-8. (ouch!) Since bsdtar defaults to pax format, this
affects bsdtar rather heavily.
To correctly support the new "hdrcharset" header that is going into
SUS and to handle conversion failures in general, libarchive's pax reader
and writer have been overhauled fairly extensively. They used to do
most of the pax header processing using wchar_t (Unicode); they now do
most of it using char so that common logic applies to either UTF-8 or
"binary" strings.
As a bonus, a number of extraneous conversions to/from wchar_t have
been eliminated, which should speed things up just a tad.

rely on a deprecated value to set the default. This is also
related to a longer-term goal of setting the default block
size based on format and possibly other factors, which makes
it a bad idea to tie this to a published constant.
new interface. Mark the functions that are going away in
libarchive 3.0.
In particular, archive_version_string() now computes the
string rather than assuming that it will be created by the
build infrastructure. Eventually, this will allow some
simplification of the build infrastructure.
* There are now only two public version identifiers: "number" is
a single integer that combines Major/minor/release in a single
value of the form Mmmmrrr. This is easy to compare against for
checking feature support. "string" is a displayable text string
of the form "libarchive M.mm.rr".
* The number is present both as a macro (version of the installed header)
and a function (version of the shared library). The string form
is available only as a function.
* Retain the older version definitions for now, but mark them all
as deprecated, to disappear in libarchive 3.0 (whenever that happens).
* Rework the various deprecation conditionals to use ARCHIVE_VERSION_NUMBER.
An ancillary goal is to reduce the number of @...@ substitutions that
are required. Someday, I might even be able to avoid build-time
processing of archive.h entirely.
Remove the entirely pointless symbolic constant
and sizeof(unsigned char). (The constant
here is doubly wrong, since not only does
it obscure a basic format constant, it was
never intended to be a tar-specific value,
so could conceivably be changed at some point
in the future.)
filename table whose size is less than 65536 bytes.
The original intention was to not consume the filename table, so the
client will have a chance to look at it. To achieve that, the library
call decompressor->read_ahead to read(look ahead) but do not call
decompressor->consume to consume the data, thus a limit was raised
since read_ahead call can only look ahead at most BUFFER_SIZE(65536)
bytes at the moment, and you can not "look any further" before you
consume what you already "saw".
This commit will turn GNU/SVR4 filename table into "archive format
data", i.e., filename table will be consumed by libarchive, so the
65536-bytes limit will be gone, but client can no longer have access
to the content of filename table.
'ar' support test suite is changed accordingly. BSD ar(1) is not
affected by this change since it doesn't look at the filename table.
