Several examples trim their buffer with an extra LWS_PRE from the end...
actually end should point to end the end of buf without a second LWS_PRE
reservation.

This adds apis that enable usage of compressed backtraces in heap
instrumentation.
A decompressor tool is also provided that emits a textual
call stack suitable for use with addr2line.
VFS needs some small updates... pass in the bound fops as well as the
context fops to the member callbacks. ZIP_FOPS only cared about doing
operations on the platform / context vfs to walk the ZIP file, but other
uses are valid where we are doing operation inside the bound VFS itself.
Also, stash a cx pointer into file ops struct for convenience.
Although many of the examples must be run from the example directory as
cwd, everyone getting started probably wants to try the examples, cmake
knows how to do it, so let's enable it by default.
Add some exports so the api test can inject results into the parser for
live queries, suppressing asking the server but otherwise following the
flow.
Provide two new suspect responses for injection and parsing in ctest.
Add a --cos option to minimal-http-client to force a close after the
connection has started the async dns.
