This adds support for counter cookies in org lists. Such cookies are
used to override the item counter in ordered lists. In org it is
possible to set the counter at any list item, but since Pandoc AST does
not support this, we restrict the usage to setting an offset for the
entire ordered list, by using the cookie in the first list item.
Note that even though unordered lists do not have counters, Org Mode
still parses such cookies in unordered lists and suppresses them in the
output, so we do the same.
Also, even though org-list-allow-alphabetical is disabled in Emacs by
default, for some reason alphabetical cookies are always parsed and used
in Org Mode regardlessly of whether this option is enabled or the list
style is decimal, so we do the same.
E.g.
2. test
3. test
Is parsed as an ordered list starting at 1, as before. This also
conforms to Org Mode behaviour.
1. [@2] test
2. test
Is now parsed as an ordered list starting at 2, so that it conforms to
Org Mode behaviour.
Note that when parsing
1. [@2] test
2. [@9] test
the second cookie is silenced and the entire list starts at 2. This is
because the current Pandoc AST does not support expressing a change in
the counter at a specific item.

This commit adds copyright notices everywhere via haddock module

been removed.

Closes#4592.
Emphasis was not parsed when it followed directly after some block types
(e.g., lists).
The org reader uses a wrapper for the `parseFromString` function to
handle org-specific state. The last position of a character allowed
before emphasis was reset incorrectly in this wrapper. Emphasized text
was not recognized when placed directly behind a block which the reader
parses using `parseFromString`.
Fixes: #4784
The org reader test file had grown large, to the point that editor
performance was negatively affected in some cases. The tests are spread
over multiple submodules, and re-combined into a tasty TestTree in the
main org reader test file.
