Item Ordering:
Fixes having an issue number are sorted by their number, ascending.
There is no ordering by add/update/fix/scode/docs/design.
Other fixed issues are added to the end of the list, chronologically.
They eventually become mixed with the numbered issues (i.e., numbered
issues do not "pop up" wrt. others).

When writing an HTTP/2 response via sendfile (only enabled when

</fix>
<fix>
Modify the HTTP/2 connector not to sent small updates for stream flow
control windows to the user agent as, depending on how the user agent is
written, this may trigger small writes from the user agent that in turn
trigger the overhead protection. Small updates for stream flow control
windows are now combined with subsequent flow control window updates for
that stream to ensure that all stream flow control window updates sent
from Tomcat are larger than <code>overheadWindowUpdateThreshold</code>.
(markt)

<add>
Add additional debug logging to track the current state of the HTTP/2
overhead count that Tomcat uses to detect and close potentially
malicious connections. (markt)
</add>
<update>
Many HTTP/2 requests from browsers will trigger one overhead frame and
one non-overhead frame. Change the overhead calculation so that a
non-overhead frame reduces the current overhead count by 2 rather than
1. This means that, over time, the overhead count for a well-behaved
connection will trend downwards. (markt)
</update>
<update>
Change the initial HTTP/2 overhead count from <code>-10</code> to
<code>-10 * overheadCountFactor</code>. This means that, regardless of
the value chosen for <code>overheadCountFactor</code>, when a connection
opens 10 overhead frames in a row will be required to trigger the
overhead protection. (markt)
</update>
<update>
Increase the default <code>overheadCountFactor</code> from
<code>1</code> to <code>10</code> and change the reduction in overhead
count for a non-overhead frame from <code>-2</code> to <code>-20</code>.
This allows for a larger range (0-20) to be used for
<code>overheadCountFactor</code> providing for finer-grained control.
