Attribute lists are represented as associative lists in Lua. Pure
associative lists are awkward to work with. A metatable is attached to
attribute lists, allowing to access and use the associative list as if
the attributes were stored in as normal key-value pair in table.
Note that this changes the way `pairs` works on attribute lists. Instead
of producing integer keys and two-element tables, the resulting iterator
function now returns the key and value of those pairs. Use `ipairs` to
get the old behavior.
Warning: the new iteration mechanism only works if pandoc has been
compiled with Lua 5.2 or later (current default: 5.3).
The `pandoc.Attr` function is altered to allow passing attributes as
key-values in a normal table. This is more convenient than having to
construct the associative list which is used internally.

even for chapter sections in epubs.
This causes problems because writers aren't set up to
expect these.
This fixes the most immediate problem in #4076.
It would be good to think more about how to propagate
the information that top-level headers are chapters
from the reader to the writer.
The `text` module is preloaded in lua. The module contains some UTF-8
aware string functions, implemented in Haskell. The module is loaded on
request only, e.g.:
text = require 'text'
function Str (s)
s.text = text.upper(s.text)
return s
end
+ Added new `HasSyntaxExtensions` typeclass for `ReaderOptions` and `WriterOptions`.
+ Reimplemented `isEnabled` function from `Options.hs` to accept both `ReaderOptions`
and `WriterOptions`.
+ Replaced `enabled` from `CommonMark.hs` with new `isEnabled`.
This fixes a bug where pandoc would stop parsing a URI with an
empty attribute: for example, `&a=&b=` wolud stop at `a`.
(The uri parser tries to guess which punctuation characters
are part of the URI and which might be punctuation after it.)
Closes#4068.
Refactored some code from Text.Pandoc.Lua.PandocModule
into new internal module Text.Pandoc.Lua.Filter.
Add `walk_inline` and `walk_block` in pandoc lua module.
