8deaec122e [analyzer] Update Fuchsia checker to catch releasing unowned handles.
Certain Fuchsia functions may return handles that are not owned by the
current closure. This adds a check in order to determine when these
handles are released.

3ce78f54ed [analyzer] Ignore annotations if func is inlined.
When we annotating a function header so that it could be used by other
TU, we also need to make sure the function is parsed correctly within
the same TU. So if we can find the function's implementation,
ignore the annotations, otherwise, false positive would occur.
Move the escape by value case to post call and do not escape the handle
if the function is inlined and we have analyzed the handle.

914f6c4ff8 [StaticAnalyzer] Support struct annotations in FuchsiaHandleChecker
Support adding handle annotations to sturucture that contains
handles. All the handles referenced by the structure (direct
value or ptr) would be treated as containing the
release/use/acquire annotations directly.
