Fix invalid pointer free inside other heap's block
1. `e = mrb_obj_alloc(...)`
2. `e->stack = mrb->c->stack` (`mrb->c->stack` is anywhere in the range `stbase...stend`)
3. And raised exception by `mrb_malloc()`!
4. `mrb_free(e->stack)` by GC part (wrong free)

Fix memory leak for string object when out of memory
The `mrb_str_pool()` function has a path to call `malloc()` twice.
If occurs `NoMemoryError` exception in second `malloc()`,
first `malloc()` pointer is not freed.

Fix stack overflow when out of memory
As a result of this change, no backtrace information is set
for NoMemoryError (`mrb->nomem_err`).
Detailes:
When generating a backtrace, called `mrb_intern_lit()`,
`mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with
`exc_debug_info()` function in `src/error.c`.
If a `NoMemoryError` exception occurs at this time,
the `exc_debug_info()` function will be called again,
and in the same way `NoMemoryError` exception raised will result
in an infinite loop to occurs stack overflow (and SIGSEGV).

Fix NULL pointer dereference `mrb->nomem_err` when not initialized
Add internal functions (not `static`):
* `mrb_raise_nomemory()`
* `mrb_core_init_abort()`
- It can now deal with operands in the range of `OP_EXT*`.
- It can now call the same method as the variable name without arguments.
```ruby
def a
"Safe!"
end
a = "Auto!"
eval "a()" # call method `a`
```
We made it `64` which should be big enough:
- Format modifier: 4 characters max
- Maximum width: 19 digits max
- Period between width and precision: 1 character
- Maximum precision: 19 digits max
- Format specifier: 1 character
- NUL terminator: 1 byte
- Total: 45 < 64
I sometimes see Bison related problems in setting up build environments.
Therefore to remove Bison from build time dependencies, add `y.tab.c`
generated by Bison to the repository.
The reduction of dependency at build time also reduces the labor and time
for setup and installation in CI.
In addition, a path in `#line` directive is converted to a relative path so
that its path is constant regardless of development environments.
Formerly, `__send__(*args)` modified `args` with `Array#shift`.
This bug affects optcarrot.
This changeset avoids the array destruction by using
`args = args[1, len-1]`.
The following error occurs when using `rake -m` on AppVeyor:
```
fatal error C1041: cannot open program database 'C:\projects\mruby\vc140.pdb'; if multiple CL.EXE write to the same .PDB file, please use /FS
```
Therefore, the issue is solved by not creating the PDB file. It is expected
to be somewhat faster by not generating debugging information (I don't think
debugging information is necessary for normal CI).
### Example
```ruby
# example.rb
class A
def eql?(o)
p self.class
super
end
def hash
1
end
end
class B < A; end
h = {A.new => 1}
h[B.new]
```
#### Before this patch:
```console
$ bin/mruby example.rb
A
```
#### After this patch (same as Ruby)
```console
$ bin/mruby example.rb
B
```
