Some of the original limited features have been developed

[summary]
1. Fix int signed & unsigned: -2147483648 and [2147483648, 4294967295] is not allowed.
2. Fix bigint signed & unsigned: -9223372036854775808 and [9223372036854775808, 18446744073709551615] is not allowed.
3. Like int&bigint, fix unsigned [tinyint, smallint, mediumint] unsupported values except negative data.

fix: change auto_increment.testbak to backup test, the cases in this file test unsigned, this will be opened after we completely support unsigned types #1151

[summary]

tinyint: signed range is -128 to 127, unsigned range is 0 to 127.

smallint: signed range is -32768 to 32767, unsigned range is 0 to 32767.

mediumint: signed range is -8388608 to 8388607, unsigned range is 0 to 8388607.

int/integer: signed range is -2147483647 to 2147483647, unsigned range is 0 to 2147483647.
Note: -2147483648 is not allowed in tianmu engine currently.

bigint: signed range is -9223372036854775806 to 9223372036854775807, unsigned range is 0 to 9223372036854775807.
Note: -9223372036854775807 will be set to null and -9223372036854775808 will ret out of range.

[summary]
add mtr test cases about unsigned/escape/replace into/zerofill

[summary]
The root cause:
before: we used "*reinterpret_cast<int64_t *>(field->ptr)" to store value from longlong, it will make "ptr" little-endian bytes order and will get wrong value when used Field_bit::val_int() to get bit value back. "val_int()" parse data according big-endian bytes order.

after fix: we use "type_conversion_status Field_bit::store(longlong nr, bool unsigned_val)" to store longlong val. Stored in big-endian bytes order.

When do insert ... select .../create ... select/update or delete in primary-secondary synchronization, the function next will be called:
---
 static void do_field_int(Copy_field *copy)
 {
   longlong value= copy->from_field()->val_int();---->here that make the data uncorrect when parsing data stored in little-endian in field->ptr
   copy->to_field()->store(value,
                           MY_TEST(copy->from_field()->flags & UNSIGNED_FLAG));
 }

[summary]
1 fix sql load when varchar column's char length(should be byte length) exceeds input-text byte length;
2 support user varialbe "TIANMU_LOAD_NULL" to customize the export file content;
3 fix the NULL value of exporter when enclosed char is not empty;

Print the specific information of known exceptions to better understand the cause of the problem

Add test cases for ALTER TABLE when exception occurs by inplace algorithm

feat(tianmu): rm some useless comment, bit type judge and add select...where test case on bit types #919

[summary]
1. revert some vars renaming code to keep old style.
2. fix type cast using reinterpret_cast to avoid c-style casting.
3. add more test cases and fix some errors.
4. format code.

[summary]
impl load bit, including empty space and null value, to keep the src code integrity, we add
an bit parse function just like others numeric does.

[summary]
1. impl insert with mode delayed=0/1
2. impl simple select bit data from table

[summary]
1. add support to create table with bit type
2. add support to desc/show fields with bit type table
3. currently we design bit(M) with (1 <= M <= 63), in the future we'll expand prec to 64.

1. Handle the result set error caused by character transfer(#1157)(#1162)
2. Handle the result set problem caused by ESCAPE keyword(#1162)

There is a problem with the judgment condition. You cannot ignore the case where the primary key value is 0

Add test case: when alter table xxx add colmn operation is failed firstly, executing
alter table xxx add colmn by successful case again

Delete the temporary directory to solve the copy problem

Using ulonglong type to accpet unsigned data for mathematics

Add LN(),LOG(),LOG2() mathematical operation test cases to test unsigned type

1.Repair the (ha_tianmu:: index_read) interface
2.Repair the (ha_tianmu:: position) interface
3.Repair the (ha_tianmu::rnd_pos) interface

The tianmu engine only supports primary keys,
and unique constraints and secondary indexes are not supported,
Therefore, only scanning with primary key scenarios is allowed here.
