The attached patch contains a couple of fixes in the existing probes

- Fixed compilation errors on OS X for probes that use typedefs
Could you explain what these errors are about? I don't see any errors
on my machine.
In the current probes.d, the following probe definitions are commented
out because they cause compilation errors on OS X.
* probe lock__wait__start(unsigned int, LOCKMODE);
* probe lock__wait__done(unsigned int, LOCKMODE);
* probe buffer__read__start(BlockNumber, Oid, Oid, Oid, bool);
* probe buffer__read__done(BlockNumber, Oid, Oid, Oid, bool, bool);
The problem was fixed by making the changes below. probes.d is
preprocessed with cpp and as such only macros get expanded.
From:
typedef unsigned int LocalTransactionId;
typedef int LWLockId;
typedef int LWLockMode;
typedef int LOCKMODE;
typedef unsigned int BlockNumber;
typedef unsigned int Oid;
typedef int ForkNumber;
To:
#define LocalTransactionId unsigned int
#define LWLockId int
#define LWLockMode int
#define LOCKMODE int
#define BlockNumber unsigned int
#define Oid unsigned int
#define ForkNumber int
