core/linux: Move I/O completion to io_uring
...
Move the Completion::complete() call to the io_uring machinery. We still
essentially do synchronous I/O because of the call to submit_and_wait()
in pread(), but let's take one step at a time...

core: Switch to using Arc<Completion>
...
We need to be able to leak a reference for io_uring so switch to
Arc<Completion> in the code.

core: Split page reading into I/O and parsing
...
In preparation for actually making page reads async, split page reading
into two parts: I/O submission with `begin_read_btree_page()` and
parsing with `finish_read_btree_page()`. Also wire up completion to
perform the read parsing.
Next step is to move the Completion.complete() call somewhere in the I/O
layer and make sure we return from the VM correctly if page is under
I/O.

core: Populate page contents lazily
...
We need to be able to allocate a new page and insert it into a page
cache without contents for asynchronoous I/O. Let's do that by making
`contents` optional in Page. (We perhaps ought to rename it to
`inner`...)

Fix full table scans
...
A full table scan missed some of the last rows because we don't consider
sibling pages when there is no parent.
