c70796b9fb add a capnp annotation for creating name spaces 
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.

6661fc9d2d Fix code generation for nested unions. 
When a union is nested inside another union, it must be enclosed in a struct
so that its "which" member is not overlapping with its other members.

9153fc39c4 Add an annotation to typedef structs and enums. 
A new annotation 'typedefto' allows you to make a typedef in the generated
code for structs and enums (but not union 'which' enums).

b995a09c03 Add an annotation to skip including header files generated from specific 
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.

e13c143c99 Fix bug where enums were treated interchangeably with uint16_t. 
ANSI C makes no guarantee about the size of an enum, only that it will be the
minimum required integer type that can hold all the given values. Treating
enums as interchangeable with uint16_t data caused undefined behavoiur on
platforms where enums were always at least 32 bits.

aa1f31d401 Silence empty struct warning 
Last but not least, -Wpedantic warns about empty structs.  With this,
-Wpedantic build is now clean of warnings on gcc 5.4.0 and clang 4.0.

b0810da2c3 Silence warning on unused struct parameter 
When generating code for an empty struct, the read_/write_ functions
would print warnings about the unused "s" pointer.  Silence these.

We need the unnamed struct/union support, this is user-facing API.
So, silence the -Wpedantic warning.
