Bug 571373 - Move typelib docs from typelib-format.txt into girepository.h

Browse Source 
typelib-format.txt was growing out of date; a good solution to this is
to move it closer to the code it's documenting.  By doing this we also
gain the ability to use gtk-doc on it.

/**
* SECTION:gtypelib
* @short_description: Layout and accessors for typelib
* @stability: Stable
*
* The "typelib" is a binary, readonly, memory-mappable database
* containing reflective information about a GObject library.
*
* The format of GObject typelib is strongly influenced by the Mozilla XPCOM
* format.
*
* Some of the differences to XPCOM include:
* - Type information is stored not quite as compactly (XPCOM stores it inline
* in function descriptions in variable-sized blobs of 1 to n bytes. We store
* 16 bits of type information for each parameter, which is enough to encode
* simple types inline. Complex (e.g. recursive) types are stored out of line
* in a separate list of types.
* - String and complex type data is stored outside of typelib entry blobs,
* references are stored as offsets relative to the start of the typelib.
* One possibility is to store the strings and types in a pools at the end
* of the typelib.
*
* The typelib has the following general format.
*
* typelib ::= header, directory, blobs, annotations
*
* directory ::= list of entries
*
* entry ::= blob type, name, namespace, offset
* blob ::= function|callback|struct|boxed|enum|flags|object|interface|constant|errordomain|union
* annotations ::= list of annotations, sorted by offset
* annotation ::= offset, key, value
*
* Details
*
* We describe the fragments that make up the typelib in the form of C structs
* (although some fall short of being valid C structs since they contain multiple
* flexible arrays).

- shrink directory entries to 12 bytes
- merge struct and boxed blobs
- split interface blobs into enum, object and interface blobs
- add an 'unregistered' flag to struct and enum blobs
- add a 'wraps_vfunc' flag to function blobs and link them to
the vfuncs they wrap
- restrict value blobs to only occur inside enums and flags again
- add constant blobs, allow them toplevel, in interfaces and in objects
- rename 'receiver_owns_value' and 'receiver_owns_container' to
'transfer_ownership' and 'transfer_container_ownership'
- add a 'struct_offset' field to virtual function and field blobs
- add 'dipper' and 'optional' flags to arg blobs
- add a 'true_stops_emit' flag to signal blobs
- add variable blob sizes to header
- store offsets to signature blobs instead of including them directly
- change the type offset to be measured in words rather than bytes
