d3015ad854 Merge 'Fix NextAwait's next instruction; rename rewind_labels' from Arpit Saxena
Closes #351
NextAwait's next instruction was pointing to RewindAwait earlier which
is not current. The instruction now points to the instruction after
RewindAwait, which will be the loop body. Hence, rename rewind_labels to
scan_loop_body_labels to make it clearer

0597c048fc Better support for BLOBs
- Limbo command line shell supports e.g. `SELECT x'616263';`
- `EXPLAIN SELECT x'616263';` lists the opcode

Missing:

- Command line shell not entirely compatible with SQLite when blobs have
  non-printable characters in the middle (e.g. `SELECT x'610062';`)
- Python bindings not supported (incoming soon)

a8b8c1d2c9 Merge 'Fix clippy ' from Kim Seon Woo
### Changes
- Remove clippy warning messages
- Add `#[allow(clippy...)]` in places where it might be better not to
fix
### TODO
recommended changes by `cargo fmt` on my local and github differs on
`sqlite3/src/lib.rs`. Should check for the reason
=> just upgrade the rust toolchain

Closes #329

Closes #319
1. Allow using a column as the pattern
2. Construct LIKE regexes with `^` and `$` so that eg the string
`'foobar'` does not match the pattern `'fooba'` unless the pattern
specifically has a wildcard
3. Support function expressions as the LIKE pattern

5da38aa11d Merge 'core: fix concat function wrong start_register' from Sonny
## What does PR do?
- fix concat function wrong start_register

## Current behavior
- addr 4 `r[1]=func(r[1..])`
- `r[1]` is target register to store the result, should not be the start reg of the function arguments
- it should be `r[1]=func(r[2..])` where
  - `r[2]` is the start of arguments
  - `r[1]` is target register to store the result

```
