https://ci.nodejs.org/job/node-test-commit-v8-linux/configure echoes
python code into tools and runs it. Move these scripts into tools for
better maintainability.

Once this lands and is back-ported into LTS branches a bunch of shell
code can be deleted from the job.

The ability to pause input processing was added in 8a4a193 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).

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.

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.

MAX_HWM was added in 9208c89 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.
