The SIGABRT handler can no longer invoke abort() recursively.

The size of a slab entry is now calculated inside a single local function, rather than calculated differently in different parts of stdlib_slab.c. This change made it easier to simplify the implementation.
7207c96a6f
Made the slab allocator work with libunix.a again.

Fixed to make use of the aligned slab address when verifying that the slab node is present in the slab. The requested slab size is now properly rounded up to a power of 2 and will always be limited to a valid range.

Fixed the MemoryNode padding, which was short of a 32 bit word.

If the memory management system constructor fails, it now prints some diagnostic debug output.
71708e84ce
The memory debugging code now places the the damage detection areas which bracket the allocation area so that the originally requested allocation size is used, not the rounded-up size. Debug output in memory node checking no longer counts the non-breaking space character as unprintable.
3d70b18c23
Simplified how the slab allocator, the memory pool or AllocMem() are being used. Added robust integer overflow detection. Allocation sizes are now padded to a multiple of MEM_BLOCKSIZE. Repaired how the plain AllocMem() allocations are managed. alloca() cleanup is disabled during the stdlib_memory_exit destructor's work. The stdlib_memory_init constructor is more robust and now insists that exec.library V39+ uses memory pools.

Updated to properly use the MemoryNode changes.
b9463f442b
Added notes on calloc() being safe to use under certain circumstances if the number of elements or the element size happens to be 0. In effect, malloc() will decide what is going to happen.

If alloca() would end up returning a NULL pointer, it now invokes the default alloca trap function, which calls abort(). You can override this, if you need to.
6197531c90
Added integer overflow checking for the element_size and count parameters.
b94937ff38
Fixed the bug which broke both fgets() and gets(): copying data from the FILE buffer failed to bump the destination string pointer. Also added an abort check in order to avoid turning the memcpy() operation into an uninterruptable sequence.
2cb54d48a9
Added the common function which both fputs() and puts() share now.
a7389454bb
fputs() and puts() now share the same common code. Added abort checks in order to avoid turning the memcpy() operations into an uninterruptable sequence.
45d118101a
Added assertion test for the buffer alignment padding size.

The inner loop of the read operation already fills the buffer as far as it can go. No need to drop into "continue;".
