Parsed statements are not CQL statements so we shouldn't inherit from the
latter although commit 485620a ("cql3: Fix cql_statement and parsed_statement
confusion") claims otherwise.
This is needed to convert classes such as UpdateStatement.ParsedInsert.

Tell all waiters that something bad happened and they should all go away.
Can be used only once; waiters should clean up and there must not be any
new waiters.
Run the build command directly in docker, using a shell function, instead
of opening a shell. Forward the user/group IDs so the build artifacts belong
to the user, not root.
When size > align, we simply call the small allocator with the provided size,
but that does not guarantee any alignment above the default.
Round the allocation size to the nearest power of two in that case, to
guarantee alignment.
rss_bits should be equal to the number of bits HW used in its RSS calculation.
Use dev_info.max_rx_queues if dev_info.reta_size is not available.

Library-imposed smart pointers, such as std::exception_ptr, may free on
a cpu other than the one they were allocated on. Unfortunately it is
impossible to wrap std::exception_ptr, since it interacts directly with the
stack unwinder.
Fix by allowing cross-cpu frees. It's a slow path, so do not abuse.
Calling state.get() will throw the exception instead of calling the function,
thus denying the called function the chance to deal with the exception.
Fix by constructing the future directly from state.
Currently we require that memory be freed on the same cpu it was allocated.
This does not impose difficulties on the user code, since our code is already
smp-unsafe, and so must use message-passing to run the destructor on the
origin cpu, so memory is naturally freed there as well.
However, library code does not run under our assumptions, specifically
std::exception_ptr, which we do transport across cores.
To support this use case, add low-performance support for cross-cpu frees,
using an atomic singly linked list per core.
It only supports -help at the moment. It is quite annoying to see:
$ ./httpd -h
terminate called after throwing an instance of
'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::program_options::unknown_option> >'
what(): unrecognised option '-h'
Aborted
Support both -h and --help.
Import CQL namespaces in the antlr-generated header file to avoid having
to use fully qualified names in the grammar file. This is considered bad
practice because of naming conflicts but we can contain it by
introducing wrappers for the main parser entry point.
