92be5bc8ae [t:5133] properly fix the memory leak introduced earlier today. 
the big idea is that we need to allocate space for a leaf entry and keep it around if we want to create a ULE for it. so now the provisional info holds a pointer to both the le and the ule so the caller can free it later.

fb72102eeb close[t:5134] le_cursor api cleaned up, followed up on a TODO to get rid of the DB parameter from is_key_right (and improved its name too) by using a fake_db in the le_cursor plus the new toku_ft_get_descriptor() api to grab a descriptor reference. refactored some tests to get it all compiling. LE and hot indexer tests pass

5c4b1d60ce close[t:5128] updating a descriptor now has two parts: user API that passes a FT and descriptor, and a low layer API that takes those two plus an explicit descriptor. we use the low layer one for deserialization code that wants to upgrade a descriptor for an FT that is not fully opened yet (and thus whose FT does not have a valid cachefile yet). this seems to be a clean enough solution, since it helps some upgrade code do non-standard stuff. 
most importantly, loader-stress-test3 no longer fails by segfaulting on ft->cf->fd

0a1d95065c [t:4838] the locktree now opens its own ft handle when created to ensure that the ft stays in memory so long as the lock tree is in memory. we use an on_create and on_destroy callback to keep the txn/ft logic out of the locktree. the api for toku_ltm_get_lt is a little hairy now. a better solution may come in the future. for now, the original failing test passes.
