43145: storage/diskmap: remove SortedDiskMapIterator.{Key,Value} r=petermattis a=petermattis
Remove `SortedDiskMapIterator.{Key,Value}` as these accessors are
horribly slow due to performing an allocation on every call. Change the
existing uses of these methods to `Unsafe{Key,Value}` adding copying
when necessary. Most of the use cases were easy to fix, though note that
`diskRowIterator.Row()` contains a TODO because the removal of the
allocation there caused many test failures.
The `PebbleMapIteration` benchmarks still show a regression in
comparison to f5009c8. That regression
is entirely due to Pebble's new memtable sizing heuristics which start
with a small memtable size and dynamically grow the size up to the
configured limit. Adding a knob to disable that behavior for the
purposes of a benchmark does not seem worthwhile.

43214: sql: stop swallowing errors from UncachedPhysicalAccessor.IsValidSchema r=andreimatei a=ajwerner
Before this commit we'd swallow retriable errors during execution. This can
be very problematic as it can lead to lost writes and other general funkiness.
We're opting to not write a test for this specific case as there is ongoing
work to change interfaces to preclude this sort of bug.
Fixes #43067
Fixes #37883 (comment)
