* Fix runtime error when IndexedTableJoinMatcher matches long selector to unique string index.
The issue arises when matching against a long selector on the left-hand side to a string
typed Index on the right-hand side, and when that Index also returns true from areKeysUnique.
In this case, IndexedTableJoinMatcher would generate a ConditionMatcher that implements
matchSingleRow by calling findUniqueLong on the Index. This is inappropriate because the Index
is actually string typed. The fix is to check the type of the Index before deciding how to
implement the ConditionMatcher.
The patch adds "testMatchSingleRowToUniqueStringIndex" to IndexedTableJoinMatcherTest, which
explores this case.
* Update tests.
* Granularity: Introduce primitive-typed bucketStart, increment methods.
Saves creation of unnecessary DateTime objects in timestamp_floor and
timestamp_ceil expressions.
* Fix style.
* Amp up the test coverage.
They all use Long.compare, but they don't need to. Changing to
regular comparisons simplifies the code and also removes branches.
(Internally, Long.compare has two branches.)
* Vectorized theta sketch aggregator.
Also a refactoring of BufferAggregator and VectorAggregator such that
they share a common interface, BaseBufferAggregator. This allows
implementing both in the same file with an abstract + dual subclass
structure.
* Rework implementation to use composition instead of inheritance.
* Rework things to enable working properly for both complex types and
regular types.
Involved finally moving makeVectorProcessor from DimensionHandlerUtils
into ColumnProcessors and harmonizing the two things.
* Add missing method.
* Style and name changes.
* Fix issues from inspections.
* Fix style issue.
* Retain order of AND, OR filter children.
If we retain the order, it enables short-circuiting. People can put a
more selective filter earlier in the list and lower the chance that
later filters will need to be evaluated.
Short-circuiting was working before #9608, which switched to unordered
sets to solve a different problem. This patch tries to solve that
problem a different way.
This patch moves filter simplification logic from "optimize" to
"toFilter", because that allows the code to be shared with Filters.and
and Filters.or. The simplification has become more complicated and so
it's useful to share it.
This patch also removes code from CalciteCnfHelper that is no longer
necessary because Filters.and and Filters.or are now doing the work.

* OrFilter: Properly handle child matchers that return the original mask.
This happens when a child matcher is literally true (for example,
BooleanVectorValueMatcher). In this case, OrFilter would throw this
exception from its call to removeAll while processing the next filter:
java.lang.IllegalStateException: 'other' must be a different instance from 'this'
Also update the javadocs for VectorValueMatcher to call out that the
returned object may be the same as the input mask.
* Fix style.
No existing code relies on being able to call these methods in this way.
The new tests exhaustively test all vectors up to size 7, and also test
behavior the run-on-self behavior that has been adjusted by this patch.

* RowBasedIndexedTable: Add specialized index types for long keys.
Two new index types are added:
1) Use an int-array-based index in cases where the difference between
the min and max values isn't too large, and keys are unique.
2) Use a Long2ObjectOpenHashMap (instead of the prior Java HashMap) in
all other cases.
In addition:
1) RowBasedIndexBuilder, a new class, is responsible for picking which
index implementation to use.
2) The IndexedTable.Index interface is extended to support using
unboxed primitives in the unique-long-keys case, and callers are
updated to use the new functionality.
Other key types continue to use indexes backed by Java HashMaps.
