RFR: 8153490: Cannot setBytes() if incoming buffer's length is bigger than number of elements we want to insert.

[Mitsuru Kariya]

Fix `SerialBlob.setBytes(long pos, byte[] bytes, int offset, int length)` in the following cases:

1. `pos - 1 + bytes.length - offset > this.length() && pos - 1 + length <= this.length()`
   The original implementation throws `ArrayIndexOutOfBoundsException` but this case should end successfully.
   (test31)

2. `pos - 1 + length > this.length()`
   The original implementation throws `ArrayIndexOutOfBoundsException` but this case should end successfully. *1
   (test32)

3. `pos == this.length() + 1`
   The original implementation throws `SerialException` but this case should end successfully. *2
   (test33)

Additionally, fix `SerialClob.setString(long pos, String str, int offset, int length)` in the following cases:

1. `offset > str.length()`
   The original implementaion throws `StringIndexOutOfBoundsException` but this case should throw `SerialException`.
   (test39)

2. `pos - 1 + str.length() - offset > this.length() && pos - 1 + length <= this.length()`
   The original implementation throws `ArrayIndexOutOfBoundsException` but this case should end successfully.
   (test32)

3. `pos - 1 + length > this.length()`
   The original implementaion throws `SerialException` but this case should end successfully. *3
   (test40)

4. `pos == this.length() + 1`
   The original implementaion throws `SerialException` but this case should end successfully. *4
   (test41)

The javadoc has also been modified according to the above.

*1 The documentation of `Blob.setBytes()` says, "If the end of the Blob value is reached while writing the array of bytes, then the length of the Blob value will be increased to accommodate the extra bytes."

*2 The documentation of `Blob.setBytes()` says, "If the value specified for pos is greater than the length+1 of the BLOB value then the behavior is undefined."
   So, it should work correctly when pos == length+1 of the BLOB value.

*3 The documentation of `Clob.setString()` says, "If the end of the Clob value is eached while writing the given string, then the length of the Clob value will be increased to accommodate the extra characters."

*4 The documentation of `Clob.setString()` says, "If the value specified for pos is greater than the length+1 of the CLOB value then the behavior is undefined."
   So, it should work correctly when pos == length+1 of the CLOB value.
