e2f34232a2 refactor html mouse action
This reduces the source complexity of the html_mouse_action()
 previously this was a single function of several thousand
 lines with over 30 local variables allocated on the stack.

Variables are now mostly held in a single static structure which
 drasticaly reduces the size of stack frame required and improves
 lookup locality.

The generated code does cause two additional function calls as the
 compiler avoids inlining the sub functions. The optimiser seems to
 produce somewhat better code within the sub functions.

In the final analysis there appears to be no significant performance
 loss or gain with this change, just more readable source.

JS: Add concept of js_closethread
In order to better model content close vs destroy, add the concept

JS: Move ownership of jsthread from browser to htmlc
Since it makes more sense for the htmlc to be responsible for
when the JS thread gets destroyed, move its lifetime from the
responsibility of the browser window to the html content.

Dukky: Add refcounting to threads
In order to cope with threads which manage to navigate entirely
while executing (sadly possible) we need to handle the possibility
that a thread is destroyed by the browser but still needs to live
until it returns from whatever exec it was doing at the time.

JS: Split concept of JS context into heap and thread
In preparation for proper splitting of Javascript support into
heaps and threads, this renames the types and corrects the no-js
builds to still work.  At this time no substantive change in
semantics exists, and the duktape build won't work.

fs_backing_store: Remove cache on failure to init
If we fail to init the control file for reasons other than it
not being found, we blow away the cache in its entirety and then
try again.  We warn if the removal fails, but carry on regardless
since right now the worst that'll happen is that we'll end up
with more on disk than we know about in the cache.

fetch: Bump last_msg rather than always assigning it
If we are aborting a cURL fetch then it's possible entry to
cURL to clean up could cause a PROGRESS message to happen which
we need to not reset last_msg for, otherwise we spuriously attempt
to send an ERROR message during abort which is not a safe time for
our message callback to be used.

curl: Implement SSL chain cache in cURL fetcher
Because cURL can do connection caching behind the scenes, we
need to have a cache for the SSL certificate chains which we
send onward on first header back from cURL.

This uses the new hashmap implementation to mean that we cache
chains on a hostname:port basis.

0c34d06494 Keep the complete certificate chain from a fetch
Instead of extracting information from the X509 certificate chain in
the fetcher the entire chain is propagated in Distinguished Encoding
Rules (DER) format.

This allows all the information contained in a certificate chain to be
retained which can subsequently be presented to the user
