B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a structure (thus breaking BeOS binary compatibility), containing a counter which is incremented whenever a thread has to wait for the spinlock. * Added macros for spinlock initialization and access and changed code using spinlocks accordingly. This breaks compilation for BeOS -- the macros should be defined in the respective compatibility wrappers. * Added generic syscall to get the spinlock counters for the thread and the team spinlocks. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25752 a95241bf-73f2-0310-859d-f6bbb57e9c96
