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. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@10822
