Reimplement frwlock

1

This pull request contains a rewrite of the fair readers-writers lock (frwlock). The old code had bugs (if a spurious wakeup occured from a pthread_cond_wait, the code would fail.) The...

need a way for an application to determine if supermalloc is loaded

TokuDB looks to see if mallctl is loaded. Should we provide that function, or a different one?

When we go to the global data structure to get objects, we should go ahead and fetch all the free objects out of a folio, since it's the same amount...

gap near 128 bytes and 256 bytes

There's a gap near 128 for unaligned malloc. We don't use 128 since it's a power of two, so if you allocate 113 bytes, you get 160 bytes, which is...

Linux libc provides 8-byte-aligned data. It would be good if there was a mode in which supermalloc provided 8-byte aligned data. Right now we have sizes such as 10, 12,...

We put in some nontrivial code. Need to make sure that all the error paths actually work. Here's the call chain. We want to make sure that all these functions,...
