Julian Seward 5b1edb07f6 When generating XML output for suppressions, print the suppression
both wrapped up in XML tags (as before) but also in plain text in a
sequence of CDATA blocks.  Normally only one, but in the worst case
the raw data will have ]]> in it, in which case it needs to be split
across two CDATA blocks.

This apparently simple change involved a lot of refactoring of the
suppression printing machinery:

* in the core-tool iface, change "print_extra_suppression_info" (which
  prints any auxiliary info) to "get_extra_suppression_info", which
  parks the text in a caller-supplied buffer.  Adjust tools to match.

* VG_(apply_StackTrace): accept a void* argument, which is passed to
  each invokation of the functional parameter (a poor man's closure
  implementation).

* move PRINTF_CHECK into put_tool_basics.h, where it should have been
  all along

* move private printf-into-an-XArray-of-character functions from
  m_debuginfo into m_xarray, and make them public

* gen_suppression itself: use all the above changes.  Basically we
  always generate the plaintext version into an XArray.  In text mode
  that's just printed.  In XML mode, we print the XMLery as before,
  but the plaintext version is dumped into a CDATA block too.

* update the Protocol 4 specification to match all this.

This still isn't 100% right in the sense that the CDATA block data
needs to be split across multiple blocks if it should ever contain the
CDATA end mark "]]>".  The Protocol 4 spec has this right even though
the implementation currently doesn't.

Fixes #191189.
