This seems to be the only place where the result of GetGraphManager() is
not checked for null, at least in JackAPI. Found by llvm scan-build.

When building with MXE, the macro expansion of PRIu64 fails:

../common/JackAPI.cpp: In function 'int jack_uuid_parse(const char*, jack_uuid_t*)':
../common/JackAPI.cpp:2119:24: error: expected ')' before 'PRIu64'
     if (sscanf (b, "%" PRIu64, u) == 1) {

This could be resolved by adding those two lines:

#define __STDC_FORMAT_MACROS 1
#include <inttypes.h>

* [metadata] Metadata properties implementation.

* [metadata] Fixed for shared server metadata-base accessor; alsofixed coding/naming style.

* [metadata] Fixed a tab for space.

* [metadata] Use of Berkeley DB is now truly optional on configure time.

* [metadata] Fixed tabs for spaces, again.

* [metadata] Fixed for shared metadata-base initialization and external clients.

* [metadata] Blind-fix for windows codebase.

* [metadata] Metadata API moved into client-side library only.

* [metadata] Fixed jack_port_uuid() stubbiness, now returning a proper UUID from port index.

* [metadata] Uniform method names.

* [metadata] Fixed PropertyChangeNotify through server async call.
