When opening a file with `File.open`, and then setting the encoding with
`IO#set_encoding`, it still correctly performs CRLF -> LF conversion on
Windows when reading files with a CRLF line ending in them (in text
mode).
However, the file is opened instead with either the `rb_io_fdopen` or
`rb_file_open` APIs from C, the CRLF conversion is _NOT_ set up
correctly; it works if the encoding is not specified, but if
`IO#set_encoding` is called, the conversion stops happening. This seems
to be because the encflags never get ECONV_DEFAULT_NEWLINE_DECORATOR
set in these codepaths.
Concretely, this means that the conversion doesn't happen in the
following circumstances:
* When loading ruby files with require (that calls rb_io_fdopen)
* When parsing ruuby files with RubyVM::AbstractSyntaxTree (that calls
rb_file_open).
This then causes the ErrorHighlight tests to fail on windows if git has
checked them out with CRLF line endings - the error messages it's
testing wind up with literal \r\n sequences in them because the iseq
text from the parser contains un-newline-converted strings.
This commit fixes the problem by copy-pasting the relevant snippet which
sets this up in `rb_io_extract_modeenc` (for the File.open path) into
the relevant codepaths for `rb_io_fdopen` and `rb_file_open`.

```
strictatime
Always update the file access time when reading from a
file. Without this option the filesystem may default to a
less strict update mode, where some access time updates
are skipped for performance reasons. This option could be
ignored if it is not supported by the filesystem.

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.
