* \brief Base for directing lib{xml2,xslt} log into standard libqb backend
*
* This macro implements the core of what can be needed for directing
* libxml2 or libxslt error messaging into standard, preconfigured
* libqb-backed log stream.
*
* It's a bit unfortunate that libxml2 (and more sparsely, also libxslt)
* emits a single message by chunks (location is emitted separatedly from
* the message itself), so we have to take the effort to combine these
* chunks back to single message. Whether to do this or not is driven
* with \p dechunk toggle.
*
* The form of a macro was chosen for implicit deriving of __FILE__, etc.
* and also because static dechunking buffer should be differentiated per
* library (here we assume different functions referring to this macro
* will not ever be using both at once), preferably also per-library
* context of use to avoid clashes altogether.
*
* Note that we cannot use qb_logt, because callsite data have to be known
* at the moment of compilation, which it is not always the case -- xml_log
* (and unfortunately there's no clear explanation of the fail to compile).
*
* Also note that there's no explicit guard against said libraries producing
* never-newline-terminated chunks (which would just keep consuming memory),
* as it's quite improbable. Termination of the program in between the
* same-message chunks will raise a flag with valgrind and the likes, though.
*
* And lastly, regarding how dechunking combines with other non-message
* parameters -- for \p priority, most important running specification
* wins (possibly elevated to LOG_ERR in case of nonconformance with the
* newline-termination "protocol"), \p dechunk is expected to always be
* on once it was at the start, and the rest (\p postemit and \p prefix)
* are picked directly from the last chunk entry finalizing the message
* (also reasonable to always have it the same with all related entries).
*
* \param[in] priority Syslog priority for the message to be logged
* \param[in] dechunk Whether to dechunk new-line terminated message
* \param[in] postemit Code to be executed once message is sent out
* \param[in] prefix How to prefix the message or NULL for raw passing
* \param[in] fmt Format string as with printf-like functions
* \param[in] ap Variable argument list to supplement \p fmt format string

* \brief Indicators of which XML characters to escape
*
* XML allows the escaping of special characters by replacing them with entity
* references (for example, <tt>"""</tt>) or character references (for
* example, <tt>" "</tt>).
*
* The special characters <tt>'&'</tt> (except as the beginning of an entity
* reference) and <tt>'<'</tt> are not allowed in their literal forms in XML
* character data. Character data is non-markup text (for example, the content
* of a text node). <tt>'>'</tt> is allowed under most circumstances; we escape
* it for safety and symmetry.
*
* For more details, see the "Character Data and Markup" section of the XML
* spec, currently section 2.4:
* https://www.w3.org/TR/xml/#dt-markup
*
* Attribute values are handled specially.
* * If an attribute value is delimited by single quotes, then single quotes
* must be escaped within the value.
* * Similarly, if an attribute value is delimited by double quotes, then double
* quotes must be escaped within the value.
* * A conformant XML processor replaces a literal whitespace character (tab,
* newline, carriage return, space) in an attribute value with a space
* (\c '#x20') character. However, a reference to a whitespace character (for
* example, \c "
" for \c '\n') does not get replaced.
* * For more details, see the "Attribute-Value Normalization" section of the
* XML spec, currently section 3.3.3. Note that the default attribute type
* is CDATA; we don't deal with NMTOKENS, etc.:
* https://www.w3.org/TR/xml/#AVNormalize
*
* Pacemaker always delimits attribute values with double quotes, so there's no
* need to escape single quotes.
*
* Newlines and tabs should be escaped in attribute values when XML is
* serialized to text, so that future parsing preserves them rather than
* normalizing them to spaces.
*
* We always escape carriage returns, so that they're not converted to spaces
* during attribute-value normalization and because displaying them as literals
* is messy.
