7133de94bb inline: keep track of lines ahead 
Needed for attributes, as they cannot be parsed without backtracking.
Potentially we have to parse for attributes until the end of the block
before we can know if it is invalid attributes and we should instead
parse for other inline events.

86ee4ee520 lex: rm lex::Kind::Whitespace 
Whitespace tokens do not necessarily create new events but they work as
a delimiter for words with attributes and affect some container
delimiters. Now when we can read the source from inline, we can instead
inspect for whitespace when needed.

Removing the whitespace token allows the lexer to continue a lot longer
without stopping. E.g. a typical line in a paragraph with no special
characters can turn into a single token.

1e5e56c463 only assert in debug builds 
these are primarily used to detect bugs during e.g. fuzzing.

most of these asserts have negligible impact on performance, but if they
are not debug asserts it is not obvious that they dont affect
performance of release builds

336927faef html: avoid peek of next event 
Try to make rendering of each event independent.

The only case where we need to peek is when a backref link should be
added to the last paragraph within a footnote.

Before, when exiting a paragraph, we would peek and add the link before
emitting the close tag if the next event is a the footnote end.

Now, the paragraph end event skips emitting a paragraph close tag if it
is within a footnote. The next event will then always close the
paragraph, and if it is a footnote end, it will add the backref link
before closing.
