* Back out part of previous commit (even though it's technically correct).alex1998-09-201-1/+17
| | | | | | | | | | | 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.

* Replace memory leaking instances of realloc with non-leaking reallocf.imp1998-09-1622-46/+50
| | | | | | | | | | | In some cases replace if (a == null) a = malloc(x); else a = realloc(a, x); with simple reallocf(a, x). Per ANSI-C, this is guaranteed to be the same thing. I've been running these on my system here w/o ill effects for some time. However, the CTM-express is at part 6 of 34 for the CAM changes, so I've not been able to do a build world with the CAM in the tree with these changes. Shouldn't impact anything, but...

| | | | | | | | | - Fix some style errors I made back in 1995. - Add a new flavor of the err(3) family, which takes an explicit errno argument rather than implicitly examining errno. This will make it easier to use these functions in conjunction with modern library interfaces that return an errno value explicitly.

The compiler should limit itself to functions that are widespread, to ease porting and cross-compilation.

Weak aliases don't work in ELF unless that is the case. (Actually, I'm surprised it worked for a.out.) This should fix the undefined "inet_addr" and related symbols in various applications that fail to include <arpa/inet.h> or <resolv.h> as they are supposed to do.
