Russell Senior b6958d257e sed: update to v4.10 ...

update to version v4.10, disable building gnulib-tests to avoid
compilation errors.

Add --disable-xattr to CONFIGURE_ARGS to avoid linking an unneeded
dependency.

Changes in sed since v4.9, from NEWS:

** Bug fixes

  sed 's/a/b/g' (and other global substitutions) now works on input
  lines longer than 2GB. Previously, matches beyond the 2^31 byte offset
  would evoke a "panic" (exit 4).
  [bug present since the beginning]

  'sed --follow-symlinks -i' no longer has a TOCTOU race that could let
  an attacker swap a symlink between resolution and open, causing sed to
  read attacker-chosen content and write it to the original target.
  [bug introduced in sed 4.1e]

  sed no longer falsely matches when back-references are combined with
  optional groups (.?) and the $ anchor.  For example, this no longer
  falsely matches the empty string at beginning of line:
    $ echo ab | sed -E 's/^(.?)(.?).?\2\1$/X/'
    Xab
  [bug present since "the beginning"]

  In --posix mode, sed no longer mishandles backslash escapes (\n,
  \t, \a, etc.) after a named character class like [[:alpha:]].
  For example, 's/^A\n[[:alpha:]]\n*/XXX/' would fail to match the
  trailing newline, treating \n as a literal backslash and an 'n'
  rather than a newline.  This happened when an earlier backslash
  escape in the same regex had already been converted, shifting the
  in-place normalization buffer.
  [bug introduced in sed 4.9]

  sed --debug no longer crashes when a label (":") command is compiled
  before the --debug option is processed, e.g., sed -f<(...) --debug.
  [bug introduced in sed 4.7 with --debug]

  sed no longer rejects the documented GNU extension 'a**' (equivalent
  to 'a*') in Basic Regular Expression (BRE) mode.  Previously, this
  worked only with -E (ERE mode), even though grep has always accepted
  it in BRE mode.
  [bug present since "the beginning"]

  sed no longer rejects "\c[" in regular expressions
  [bug present since the beginning]

  'sed --follow-symlinks -i' no longer mishandles an operand that is a
  short symbolic link to a long symbolic link to a file.
  [bug introduced in sed 4.9]

  Fix some some longstanding but unlikely integer overflows.
  Internally, 'sed' now more often prefers signed integer arithmetic,
  which can be checked automatically via 'gcc -fsanitize=undefined'.

** Changes in behavior

  In the default C locale, diagnostics now quote 'like this' (with
  apostrophes) instead of `like this' (with a grave accent and an
  apostrophe).  This tracks the GNU coding standards.

  'sed --posix' now warns about uses of backslashes in the 's' command
  that are handled by GNU sed but are not portable to other
  implementations.

** Build-related

  builds no longer fail on platforms without the <getopt.h> header or
  getopt_long function.
