1754e014f5 std.heap.SmpAllocator: rotate on free sometimes 
* slab length reduced to 64K
* track freelist length with u8s
* on free(), rotate if freelist length exceeds max_freelist_len

Prevents memory leakage in the scenario where one thread only allocates
and another thread only frees.

8626191549 std.heap.GeneralPurposeAllocator: fix slot_counts calculation 
In larger small buckets, the comptime logic that computed slot count did
not verify that the number it produced was valid. Now it verifies it,
which made this bug into a compile error. Then I fixed the bug by
introducing a "minimum slots per bucket" declaration.

36e9b0f026 std.mem.Allocator: keep the undefined memset 
Reversal on the decision: the Allocator interface is the correct place
for the memset to undefined because it allows Allocator implementations
to bypass the interface and use a backing allocator directly, skipping
the performance penalty of memsetting the entire allocation, which may
be very large, as well as having valuable zeroes on them.

f1717777a2 std.heap: delete LoggingAllocator and friends 
I don't think these belong in std, at least not in their current form.

If someone wants to add these back I'd like to review the patch before
it lands.
