lziprecover: updated to 1.21

Changes in version 1.21:

The options '--dump', '--remove' and '--strip' have been added, mainly as
support for the tarlz archive format: http://www.nongnu.org/lzip/tarlz.html
These options replace '--dump-tdata', '--remove-tdata' and '--strip-tdata',
which are now aliases and will be removed in version 1.22.

  '--dump=[<member_list>][:damaged][:tdata]' dumps the members listed, the
  damaged members (if any), or the trailing data (if any) of one or more
  regular multimember files to standard output.

  '--remove=[<member_list>][:damaged][:tdata]' removes the members listed,
  the damaged members (if any), or the trailing data (if any) from regular
  multimember files in place.

  '--strip=[<member_list>][:damaged][:tdata]' copies one or more regular
  multimember files to standard output, stripping the members listed, the
  damaged members (if any), or the trailing data (if any) from each file.

Detection of forbidden combinations of characters in trailing data has been
improved.

'--split' can now detect trailing data and gaps between members, and save
each gap in its own file. Trailing data (if any) are saved alone in the last
file. (Gaps may contain garbage or may be members with corrupt headers or
trailers).

'--ignore-errors' now makes '--list' show gaps between members, ignoring
format errors.

'--ignore-errors' now makes '--range-decompress' ignore a truncated last
member.

Errors are now also checked when closing the input file in decompression
mode.

Some diagnostic messages have been improved.

'\n' is now printed instead of '\r' when showing progress of merge or repair
if stdout is not a terminal.

Lziprecover now compiles on DOS with DJGPP. (Patch from Robert Riebisch).

The new chapter 'Tarlz', explaining the ways in which lziprecover can
recover and process multimember tar.lz archives, has been added to the
manual.

The configure script now accepts appending options to CXXFLAGS using the
syntax 'CXXFLAGS+=OPTIONS'.

It has been documented in INSTALL the use of
CXXFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW.
