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.

Throwing an exception may allocate memory, which we don't want to do
in the syscall thread pool (only reactor threads support allocation, for now).
Move the conversion of negative syscall results to exceptions to a separate
task, running in the reactor thread, to avoid this.
Convert Cql.g to produce C++. To make things compile, convert the
useStatement grammar rule. Also add an ugly sed hack in configure.py to
support "#if 0" in the grammar file.
This patch also disables -Werror and enables -fpermissive for
antlr-generated code which attempts to convert a const pointer to a
non-const pointer without a cast:

Add UUID::to_sstring() method, analogous to the Java UUID.toString(),
and I verified that it generates the same output as the original Java
method.

[avi: make it build, using sprint() instead of sprintf()]
The Functions class wants to store functions in a map and hand them out later,
so we need a shared_ptr.
(could have had a map of name -> function factory, maybe one day)
Cassandra's ParsedStatement does not implement CqlStatement. Classes
such as UseStatement extend ParsedStatement and implement CqlStatement
which causes JVM to dispatch methods such as usesFunction to
ParsedStatement.
This doesn't happen in C++, of course, which leaves classes such as
use_statement abstract and thus uninstantiable.

This patch includes a helper function that executes a function for each entry
in a directory. It is future based and can include in the future, future-based
code to asychronously read, for instance, an sstable.
At the moment, it only scan all keyspaces and make sure they appear in the
keyspaces hash.
Both the database and keyspace classes gain a populate<T> factory that returns a
populated database. At this point, the names found are just listed, but not really
stored anywhere.

I am currently unable to use core/file.hh in a fresh include file. Type
conflicts arise, which probably don't happen in other existing files because
of existing includes that end up getting the environment all right beforehand.
