f2068f2c89 fix regression in xous-names blocking connect 
The `libstd` implementation has a bug where it was going through
a vector and mutating it by removing items from the vector,
but not updating the indices.

This fix goes through the vector in reverse order, so that removed
items don't affect the position of the next items in iteration order.

This seems to make the blocking connect much more stable.

5185b2ee07 xous-ticktimer: overhaul condvars 
The previous condvar implementation was unsound, and didn't do the right
thing. Overhaul condvars so that they now pass the libstd tests.

As part of this, function calls were added to free the mutex and condvar
objects that may have been allocated.

511f77f897 ticktimer: only allow RecalculateSleep from ourselves 
Rewrite the RecalculateSleep opcode handler so that it will only be
processed if sent by our own process.

As part of this rewrite, use the new `let else` pattern.

1a60fe4aad fix bugs in key invalidation/eviction logic 
1. track evictions as separate from cleanliness. not clean means
the data is dirty and needs writing back. eviction simply means
the data needs be re-retrieved from disk.

2. actually fill the data when we do a sync -- previously
we only copied the old data into the new page but then forgot
to allocate the data and assign it to the cache (oops)

3. sync the small pools after doing a remove inside the update()
command to make sure we've met invariants for future calls
to cache fills

so many corner cases, i'm going around in circles....

5d926294be only invalidate the key entry if it is within the current range of interest 
previously, we were invalidating at the first instance of
encountering the key; instead we should only invalidate once
we've processed it in our range of interest.
