    golang/xenlight: do not negate ret when converting to Error
    Commit 871e51d2d4 changed the sign on the xenlight error types (making
    the values negative, same as the C-generated constants), but failed to
    remove the code changing the sign before casting to Error().  This
    results in error strings like "libxl error: <x>", rather than the
    correct message. Fix all occurrances of this by running:
      gofmt -w -r 'Error(-ret) -> Error(ret)' xenlight.go
    from tools/golang/xenlight.

    golang/xenlight: rename Ctx receivers to ctx
    As a matter of style, it is strange to see capitalized receiver names,
    due to the significance of capitalized symbols in Go (although there is
    in fact nothing special about a capitalized receiver name). Fix this in
    xenlight.go by running:
      gofmt -w -r 'Ctx -> ctx' xenlight.go
    from tools/golang/xenlight. There is no functional change.

    golang/xenlight: use struct pointers in keyed union fields
    Currently, when marshalig Go types with keyed union fields, we assign the
    value of the struct (e.g. DomainBuildInfoTypeUnionHvm) which implements the
    interface of the keyed union field (e.g. DomainBuildInfoTypeUnion).
    As-is, this means that if a populated DomainBuildInfo is marshaled to
    e.g. JSON, unmarshaling back to DomainBuildInfo will fail.
    When the encoding/json is unmarshaling data into a Go type, and
    encounters a JSON object, it basically can either marshal the data into
    an empty interface, a map, or a struct. It cannot, however, marshal data
    into an interface with at least one method defined on it (e.g.
    DomainBuildInfoTypeUnion). Before this check is done, however, the
    decoder will check if the Go type is a pointer, and dereference it if
    so. It will then use the type of this value as the "target" type.
    This means that if the TypeUnion field is populated with a
    DomainBuildInfoTypeUnion, the decoder will see a non-empty interface and
    fail. If the TypeUnion field is populated with a
    *DomainBuildInfoTypeUnionHvm, it dereferences the pointer and sees a
    struct instead, allowing decoding to continue normally.
    Since there does not appear to be a strict need for NOT using pointers
    in these fields, update code generation to set keyed union fields to
    pointers of their implementing structs.

    golang/xenlight: export keyed union interface types
    For structs that have a keyed union, e.g. DomainBuildInfo, the TypeUnion
    field must be exported so that package users can get/set the fields
    within. This means that users are aware of the existence of the
    interface type used in those fields (see [1]), so it is awkward that the
    interface itself is not exported. However, the single method within the
    interface must remain unexported so that users cannot mistakenly "implement"
    those interfaces.
    Since there seems to be no reason to do otherwise, export the keyed
    union interface types.

    golang/xenlight: fix StringList toC conversion
    The current implementation of StringList.toC does not correctly account
    for how libxl_string_list is expected to be laid out in C, which is clear
    when one looks at libxl_string_list_length in libxl.c. In particular,
    StringList.toC does not account for the extra memory that should be
    allocated for the "sentinel" entry. And, when using the "slice trick" to
    create a slice that can address C memory, the unsafe.Pointer conversion
    should be on a C.libxl_string_list, not *C.libxl_string_list.
    Fix these problems by (1) allocating an extra slot in the slice used to
    address the C memory, and explicity set the last entry to nil so the C
    memory will be zeroed out, and (2) dereferencing csl in the
    unsafe.Pointer conversion.
