Unconditionally passing arbitrary numbers as flags turns out to be a
bad idea, because some of the "unused" values have historically had
side-effects internal to libdiscount. Detect whether the known flags
work by rendering short Markdown snippets the first time we htmlize,
checking whether each known flag is both necessary and sufficient.

An empty coder name used to detect the format implicitly, but has been
interpreted as a literal part of the filename since ImageMagick 6.9.8-3.
In newer versions, there does not seem to be any way to indicate that
a filename containing ':' is to be taken literally without first
knowing the decoder to use.

This is a minimal version of what we should in principle do here,
which is to escape the error message in whatever way is correct for
embedding plain text in the surrounding wiki markup language.
This implementation approximates that by assuming that HTML entities,
alphanumerics and common punctuation characters are passed through the
markup language unaltered, but punctuation characters might be
misinterpreted.

The Discount package in Debian historically enabled fenced code blocks,
PHP Markdown Extra-style definition lists, and an expanded character
set for tag names. Since Discount 2.2.0 those are runtime settings, so
enable them. Unfortunately Text::Markdown::Discount doesn't yet expose
the necessary constants:

The IDANCHOR option was historically also enabled in Debian, but is not
enabled here because ikiwiki does not enable the TOC option, and
IDANCHOR does nothing without TOC.
Closes: #888055
