The GitHub Super Linter is a more robust and better supported
tool than the current GitHub Actions we are using.

Added the GitHub Super Linter badge to the README.
Also updated the pre-commit framework and added
more documentation on pre-commit.
Added one more pre-commit check: check-executables-have-shebangs
Added one extra check for merge conflicts to our
GitHub Actions.
EditorConfig and Markdown linting.
Minor grammar and spelling fixes.
Update linter.yml
- define `MRB_TT_RATIONAL`
- change object structure (`struct RRational`)
- add memory management for `MRB_TT_RATIONAL`
- avoid operator overloading as much as possible
- implement division overloading in C
- as a result, performance improved a lot
Add new pool value type `IREP_TT_BIGINT` and generate integer overflow
error in the VM. In the future, `mruby` will support `Bignum` for
integers bigger than `mrb_int` (probably using `mpz`).
Normally a single spell checker can't find all the mistakes or check all types of code.
These mistakes were found by another spell checker inside my editor with a more manual sift / find.
We have introduced following new instructions.
* `OP_LAMBDA16`
* `OP_BLOCK16`
* `OP_METHOD16`
* `OP_EXEC16`
Each instruction uses 16 bits operand for `reps` index. Since new
instructions are added, `mruby/c` VM should be updated.
Due to new instructions, dump format compatibility is lost, we have
increased `RITE_BINARY_MAJOR_VER`.
In addition, we have decreased the size of `refcnt` in `mrb_irep` from
`uint32_t` to `uint16_t`, which is reasonably big enough.
The `init_SYMBOLS()` function implicitly defined in `MRB_PRESYM_DEFINE_VAR_AND_INITER()` requires some familiarity when trying to find it from the caller.
By introducing `MRB_PRESYM_INIT_SYMBOLS()`, it is possible to find directly from the identifier.
Because a structure that is an element of `presym_table` has padding, split
it into individual arrays for name and length.
#### Result (64-bit CPU with full-core gembox)
| | mruby | libmruby.a |
|--------|------------|------------|
| Before | 1,087,444B | 1,476,872B |
| After | 1,079,340B | 1,469,784B |
Instead of including `mruby/presym.h` everywhere, we provided the
fallback `mruby/presym.inc` under `include/mruby` directory, and specify
`-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`.
So even when someone drops `-I<build-dir>/include` in compiler options,
it just compiles without failure.
`calc_crc_16_ccitt()` consumes a lot of clock cycles in programs like
`mrbtest` which loads a lot of dumped binary. Error detection for flaky
channels should be done in the higher level.
Note: `mruby/c` should be updated to support this change.
This enhances self-containment.
- Changed the `mrb_callinfo::pc` field to point to itself.
Previously it indicated the return destination of the previous call level.
`mrb_callinfo::pc` will now hold the address to its own `proc->body.irep->iseq`.
- Removed `mrb_callinfo::err` field.
This is because `mrb_callinfo::pc - 1` is semantically the same as the previous `err`.
- The `pc0` and `pc_save` variables in `mrb_vm_exec()` are no longer needed and have been deleted.
- It removes the argument because `cipush()` doesn't need to save the previous `pc`.
This enhances self-containment.
Previously `mrb_context::stack` had the current call level stack, but now it owns it.
The `mrb_context::stack` field, which is no longer needed, will be removed.
