MAX_HWM was added in 9208c890 where the highwatermark was changed to
always increase in steps of highest power of 2 to prevent increasing
hwm excessivly in tiny amounts.

Why a limit was added on the highwatermark is unclear but breaks
existing usage where a larger read size is used. The invariant for
read(n) is that a buffer of size n is always returned. Considering
a maximum ceiling on the buffer size breaks this invariant.

This PR significantly increases the limit to make it less likely to
break the previous invariant and also documents the limit.

This will allow us to lint for use of `hostname` in prose without
flagging `hostname` in code within headers. This also allows us to
remove backslash escaping for `[` and `]` inside of header code, which
makes the bare markdown more readable.

Allow use of <code> in header elements without styling side effects. We
can add styling later if desired. The goal here is to allow code to be
set off in markdown without needing to escape characters and do lint
exceptions for terms. This is probably a win in terms of accessibility
too although it would be moreso if we had some visual differentiation
for <code> inside of headers. As mentioned above, that can always be
added at a later time.

The ability to pause input processing was added in 8a4a1931 but
introduced a session memory accounting mismatch leading to potential
NGHTTP2_ENHANCE_YOUR_CALM errors.

After pausing
(https://github.com/nodejs/node/blob/f36331c1bfa4c4c202346b05dc3bd672f653e4df/src/node_http2.cc#L871),
the early return on line 873 skips the
DecrementCurrentSessionMemory(stream_buf_.len) call below (line 878).

When we later finished processing the input chunk
(https://github.com/nodejs/node/blob/f36331c1bfa4c4c202346b05dc3bd672f653e4df/src/node_http2.cc#L1858),
we were calling DecrementCurrentSessionMemory(stream_buf_offset_) [line
1875] which was a no-op since we just set stream_buf_offset_ to 0 [line
1873].

The correct amount to decrement by is still stream_buf_.len, since
that's the amount we skipped previously (line 878).

If there’s a lot of data waiting on a given stream, send
it out early, if possible. This helps trigger the backpressure
mechanism introduced in 8a4a1931 at a better time.

This is an approach to address the issue linked below. Previously,
when `.write()` and `.flush()` calls to a zlib stream were interleaved
synchronously (i.e. without waiting for these operations to finish),
multiple flush calls would have been coalesced into a single flushing
operation.

This patch changes behaviour so that each `.flush()` all corresponds
to one flushing operation on the underlying zlib resource, and the
order of operations is as if the `.flush()` call were a `.write()`
call.

One test had to be removed because it specifically tested the previous
behaviour.

As a drive-by fix, this also makes sure that all flush callbacks are
called. Previously, that was not the case.
