Older versions of glibc requires extra feature macros
for function open_memstream.
fmemopen(), open_memstream(), open_wmemstream():
Since glibc 2.10:
_XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
Before glibc 2.10:
_GNU_SOURCE
src/sbus/sssd_dbus_introspect.c: In function 'introspect_begin':
src/sbus/sssd_dbus_introspect.c:82: error: implicit declaration of function 'open_memstream'
src/sbus/sssd_dbus_introspect.c:82: warning: assignment makes pointer from integer without a cast

There was a resource leak in the introspection code. This patch fixes
the leak.

Type safe method handlers allow methods not to have to do tedious
unwrapping and wrapping of DBus method call messages or replies.
Arguments of the following DBus types are supported in type-safe
method handlers. In addition arrays of these are supported.
y: uint8_t
b: bool (but no arrays, yet)
n: int16_t
q: uint16_t
i: int32_t
u: uint32_t
x: int64_t
t: uint64_t
d: double
s: char * (utf8 string)
o: char * (object path)
As an exception, arrays of booleans are not supported, but could be
added later. Other more complex types could be added later if desired.
If a method has other argument types, then it must be marked as having
a raw handler (see below).
Internally each method can have a type specific invoker function which
unpacks the incoming arguments and invokes the method handler with the
correct arguments.
Each method also has a finish which accepts the type-safe out arguments
(ie: return values) and builds the reply message. Like other request
'finish' functions, these free the request talloc context, and are to
be used in place of sbus_request_finish() or friends.
Raw method handlers parse their own method arguments, and prepare their
own reply (ideally using sbus_request_finish() helpers). They can also
do strange things like have variable arguments. To mark a DBus method
as having a raw method handler use the following annotation:
<annotation name="org.freedesktop.sssd.RawHandler" value="true"/>
Raw methods do not have invokers or finish functions.
I've left all of the internal peer to peer communication using raw
method handlers. No code changes here.

Also fixes a warning about uninitialized 'method' as the 'method'
variable was unused and not set previously when introspecting.

This patch generates the introspection data from the sbus interface meta
structure. The generated XML conforms to
http://dbus.freedesktop.org/doc/dbus-specification.html#introspection-format
The XML description of the interface also always includes the
org.freedesktop.DBus.Introspectable interface, which this patch also allows
in the policy settings.
