When working with integer constants, it is convenient to use #define
macros for the constants, as opposed to a variable of constant type.
This patch adds a '#define CONSTANT (value)' definition to the
generated header files. The name of the constant is in
SCREAMING_SNAKE_CASE, converted from the regular camelCase.

This patch adds the 'const' keyword to constant definitions generated
by the compiler. Previously the compiler generated constants like
this:
foo.h
======
extern int foo;
foo.c
======
int foo = 5;
With this patch, the generated code looks like:
foo.h
======
extern const int foo;
foo.c
======
const int foo = 5;

This patch adds an annotation for creating name spaces within
capnproto files with the C-language code generator.
Use the annotation like this:
using C = import "/c.capnp";
$C.namespace("sample_namespace_");
The string passed into the namespace annotation is prepended to the
name of all the struct's in the schema file.

This patch modifies the code generator to only generate C-language
`#include <imported_schema.h>` lines for imports that are actually used.
Imagine this transitive import scenario: schema A imports a definition
from schema B. However, the definition imported from schema B was
itself imported from schema C.
In this case, the code generated for schema A need not include the
header file for schema B, as it only needs definitions from schema C.

schema files.
Some schema files (eg. those that only decalare annotations) do not actually
result in any generated C code. They do not need to have a corresponding
include directive for C files generated from schemas that include them. This
introduces a "donotinclude" annotation that takes the Cap'n Proto ID (a
UInt64) of any such files and skips generating the include directive for them.
