Replace `tool/update-deps` with a Ruby source scanner so dependency
updates no longer require GNU make, a configured build, or compiler
preprocessor output.
Keep compact source mappings and scanner declarations in dependency
files, and expand complete rules into the build directory. Avoid the
temporary fixture headers required by the compiler-driven prototype.
Use the generated rules from GNU make, BSD make, and NMake builds.
Support out-of-tree and read-only source trees, and retain expanded
dependencies shipped in release archives when baseruby is unavailable.

[Bug #22184]
`onigmo.h` contains a lot of declarations that can easily
conflict with third party code, hence it's better to keep
it opaque. That however requires a few hacks.
When embeddeding `struct re_pattern_buffer`, `RRegexp` end up
488B large, which result in a rather minimal 24B waste in 512B slots.
This however requires a few changes:
- Stop relying on `RREGEXP_PTR == NULL` to check for initialization.
- `reg_copy` requires a new `onig_reg_copy_body` API.
In certain cases, things like Array#sort can result in a confusing error
message. For instance where a and b are characters in a string,
`"string"`:
```ruby
array.sort { |a, b| string.index(a) <=> string.index(b) }
```
If one of the index calls returns nil, we will get "comparison of String
with String failed", which is somewhat unhelpful, since it's easy to be
confused, given that what is really being compared is a Fixnum or
NilClass (the cause of the error). Yes, as far as Array#sort is
concerned, the two characters are the things being sorted, but it's
useful to call attention to the return value of the comparison in this
case.
This patch adds a "reason" argument to rb_cmperr, which will provide an
error message of "comparison of String with String failed: comparator
returned nil" in the case above, or, in the case of:
```ruby
1.upto('10').to_a
```
it will provide the message: "comparison of Fixnum with String failed:
coercion was not possible"
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
* numeric.c (int_pow): fix infinite loop in the case of y equal 1
and power of x does not overflow.

Onigumo 6 (r57045) introduced new onigumo.h header file, which is
required from quite much everywhere. This commit adds necessary
dependencies.
Note: ruby/oniguruma.h now includes onigumo.h,
ruby/io.h includes oniguruma.h,
ruby/encoding.h also includes oniguruma.h,
and internal.h includes encoding.h.

treatment for subclasses which don't have definitions of to_f method.
* numeric.c (Integer#to_f, Fixnum#to_f): move to_f method from Fixnum
to Integer.
* ext/-test-/integer/my_integer.rb: define helper class for testing
to_f method for a subclass of Integer.
* ext/-test-/integer/extconf.rb: ditto.
* ext/-test-/integer/init.c: ditto.
* test/-ext-/integer/test_my_integer.rb: examine to_f method for a
subclass of Integer.
