'RELENG_3_0_0_RELEASE'. This commit was manufactured to restore the state of the 3.0-RELEASE image. Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

Delete the XXX comments that refer to spinlock recursion. The malloc/free/

realloc functions check for recursion within the malloc code itself. In a thread-safe library, the single spinlock ensures that no two threads go inside the protected code at the same time. The thread implementation is responsible for ensuring that the spinlock does in fact protect malloc. There was a window of opportunity in which this was not the case. I'll fix that with a commit RSN.

Use 8k pagesize on alpha, not 4k.

Back out part of previous commit (even though it's technically correct).

Our spinlock implementation allows a particular thread to obtain a lock multiple times, but release the lock with a single unlock call. Since we're detecting recursion, we know the lock is already owned by the current thread in a previous call and must not be released in the current call. This is really far too dependent on this particular spinlock implementation, so I've added commented out calls to THREAD_UNLOCK in the appropriate places. We can activate this code when spinlock is taught to count each lock operation.

Correctly back out of free if a recursive call into malloc.c is detected.

Add support for thread lock debug. No impact of the malloc code.
