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.

* [enhancement](stream load pipe) using queryid or load id to identify stream load pipe instead of fragment instance id
NewLoadStreamMgr already has pipe and other info. Do not need save the pipe into fragment state. and FragmentState should be more clear.
But this pr will change the behaviour of BE.
I will pick the pr to doris 1.2.3 and add the load id to FE support. The user could upgrade from 1.2.3 to 2.x

This CL mainly changes:
Support specifying csv schema manually in s3/hdfs table valued function
s3 (
'URI' = 'https://bucket1/inventory.dat',
'ACCESS_KEY'= 'ak',
'SECRET_KEY' = 'sk',
'FORMAT' = 'csv',
'column_separator' = '|',
'csv_schema' = 'k1:int;k2:int;k3:int;k4:decimal(38,10)',
'use_path_style'='true'
)
Add new session variable dry_run_query
If set to true, the real query result will not be returned, instead, it will only return the number of returned rows.
mysql> select * from bigtable;
+--------------+
| ReturnedRows |
+--------------+
| 10000000 |
+--------------+
This can avoid large result set transmission time and focus on real execution time of query engine.
For debug and analysis purpose.

This pr implements the list default partition referred in related #15507.
It's similar as GreenPlum's default's partition which would store all data not satisfying prior partition key's
constraints and optimizer wouldn't filter default partition which means default partition would be scanned
each time you try to select data from one table with default partition.
User could either create one table with default partition or alter add one default partition.
```sql
PARTITION LIST(key) {
PARTITION p1 values in (xx,xx),
PARTITION DEFAULT
}
ALTER TABLE XXX ADD PARTITION DEFAULT
```
We don't support automatically migrate data inside default partition which meets newly added partition key's
constraint to newly add partition when alter add new partition. User should select default partition using new
constraints as predicate and insert them to new partition.
```sql
insert into tbl select * from tbl partition default where partition_key=xx;
```
sub_bitmap return type should be ALWAYS_NULLABLE, not depend on children.
For example
sub_bitmap(bitmap_empty(), 1, 2) return NULL, but all children are not null.
mainly include:
- brpc service adds two types of thread pools. The number of "light" and "heavy" thread pools is different
Classify the interfaces of be. Those related to data transmission are classified as heavy interfaces and others as light interfaces
- Add some monitoring to the thread pool, including the queue size and the number of active threads. Use these
- indicators to guide the configuration of the number of threads
Support specifying AccessControllerFactory when creating catalog
create catalog hive properties(
...
"access_controller.class" = "org.apache.doris.mysql.privilege.RangerAccessControllerFactory",
"access_controller.properties.prop1" = "xxx",
"access_controller.properties.prop2" = "yyy",
...
)
So that user can specified their own access controller, such as RangerAccessController
Add interface to check column level privilege
A new method of CatalogAccessController: checkColsPriv(),
for checking column level privileges.
TODO:
Support grant column level privileges statements in Doris
Add TestExternalCatalog/Database/Table/ScanNode
These classes are used for FE unit test. In unit test you can
create catalog test1 properties(
"type" = "test"
"catalog_provider.class" = "org.apache.doris.datasource.ColumnPrivTest$MockedCatalogProvider"
"access_controller.class" = "org.apache.doris.mysql.privilege.TestAccessControllerFactory",
"access_controller.properties.key1" = "val1",
"access_controller.properties.key2" = "val2"
);
To create a test catalog, and specify catalog_provider to mock database/table/schema metadata
Set roles in current user identity in connection context
The roles can be used for authorization in access controller.
The background is described in this issue: #15723,
where users used Apache Druid to satisfy such lambada requirements before.
We will not make Doris dropping data not belonged to current time window automatically like Druid,
which is not flexible. We demand a ability to support mutable/immutable partition, the PR works this way:
1. Support mutable property for a partition.
2. The mutable property of a partition is passed from FE to BE in a load procedure
3. If a record's partition is immutable, we mark this row as "un selected" which will not be included in computation of 'max_filter_ratio',
so that data write to immutable partition will be neglected and not cause load failure.
Use Example:
1. Add immutable partition or modify an partition to be immutable:
- alter table test_tbl add [temporary] partition xxx values less than ('xxx') ('mutable' = 'true');
- alter table test_tbl modify partition xx set ('mutable' = 'false');
2. Write 5 records into table, two of then belongs to immutable partition
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.
Now we use a thrift message per fragment instance. However, there are many same messages between instances in a fragment. So this PR aims to extract the same messages and we only need to send thrift message once for a fragment
Hive 1.x may write orc file with internal column name (_col0, _col1, _col2...).
This will cause query result be NULL because column name in orc file doesn't match
with column name in Doris table schema. This pr is to support query Hive orc files with internal column names.
For now, we haven't see any problem in Parquet file, will send new pr to fix parquet if any problem show up in the future.
Use FE cluster token to auth stream load.
This auth is only open for be, and fe auth still only support http basic auth.
I will use this auth for mysql load to build a no-auth stream load from fe to be.
And this will avoid double auth in mysql load.
More information to see the design doc.
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");

When the argument of truncate function is float type, it can match both truncate(DECIMALV3) and truncate(DOUBLE), if the match is truncate(DECIMALV3), the precision is lost when converting float to DECIMALV3(38, 0).
Here I modify it to match truncate(DOUBLE) for now, maybe we still need to solve the problem of losing precision when converting float to DECIMALV3.
both update status and open_vectorized_internal will call send_report and stop report thread. move update_status code to open method and remove unnecessary send_report and stop_report_thread.

Support set skip line number for stream load to load csv file.
Usage `-H skip_lines:number`:
```
curl --location-trusted -u root: -T test.csv -H skip_lines:5 -XPUT http://127.0.0.1:8030/api/testDb/testTbl/_stream_load
```
Skip line number also can be used in mysql load as below:
```sql
LOAD DATA
LOCAL
INFILE '${mysql_load_skip_lines}'
INTO TABLE ${tableName}
COLUMNS TERMINATED BY ','
IGNORE 2 LINES
PROPERTIES ("auth" = "root:");
```
