ECB algorithm, block_encryption_mode does not take effect, it only takes effect when init vector is provided.
Solved: 192/256 supports calculation without init vector
For other algorithms, an error should be reported when there is no init vector
Initialization Vector. The default value for the block_encryption_mode system variable is aes-128-ecb, or ECB mode, which does not require an initialization vector. The alternative permitted block encryption modes CBC, CFB1, CFB8, CFB128, and OFB all require an initialization vector.

Note: This fix does not support smooth upgrades. during upgrade process, query may report error: funciton not found
Result of select bitmap_to_string(bitmap_or(to_bitmap(1), null)) should be 1 instead of null.
This PR fix logic of bitmap_or and bitmap_or_count.
Other count related funcitons should also be checked and fix, they will be fixed in another PR.
1. change PipelineTaskState to enum class
2. remove some row-based code on FoldConstantExecutor::_get_result
3. reduce memcpy on minmax runtime filter function(Now we can guarantee that the input data is aligned)
4. add Wunused-template check, and remove some unused function, change some static function to inline function.
remove duplicate type definition in function context
remove unused method in function context
not need stale state in vexpr context because vexpr is stateless and function context saves state and they are cloned.
remove useless slot_size in all tuple or slot descriptor.
remove doris_udf namespace, it is useless.
remove some unused macro definitions.
init v_conjuncts in vscanner, not need write the same code in every scanner.
using unique ptr to manage function context since it could only belong to a single expr context.

use StringRef instead of string_view operator == for vectorized impl for array_contains function.
- test data: 10,000,000 rows with a ARRAY<STRING> column. There are 10 elements, average length 11 chars, in the array column in each row.
- test SQL: `select count() from test_like_array where array_contains(s_arr, 'xxxxxxxx');`
- test result: 0.76 sec vs. 0.52 sec, 30% time reduced
add a defer in fold constant to close.
add more type when call _get_result function in fold constant.3.
fix in can't handle null. eg:select 1 in (2, NULL, 1);
in java udf jni_ctx will be nullptr, so call close will be core dump.
Describe your changes.
1、support stream load with json, csv format for map
2、fix olap convertor when compaction action in map column which has null
3、support select outToFile for map
4、add some regression-test
Introduced a new function non_nullable to BE, which can extract concrete data column from a nullable column. If the input argument is already not a nullable column, raise an error.
Issue Number: close#16351
Dynamic schema table is a special type of table, it's schema change with loading procedure.Now we implemented this feature mainly for semi-structure data such as JSON, since JSON is schema self-described we could extract schema info from the original documents and inference the final type infomation.This speical table could reduce manual schema change operation and easily import semi-structure data and extends it's schema automatically.
This commit support:
1、Insert + select for struct/map type
2、Json stream load for struct type
3、m[key] function for map type
How to use:
Set the fe config to create table for struct and map type
1、admin set frontend config("enable_struct_type" = "true");
2、admin set frontend config("enable_map_type" = "true");
