Split ruby.h

卜部昌平 5e22f873ed decouple internal.h headers
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).

卜部昌平 0e8219f591 make functions static
These functions are used from within a compilation unit so we can
make them static, for better binary size.  This changeset reduces
the size of generated ruby binary from 26,590,128 bytes to
26,584,472 bytes on my macihne.

schneems 94b79bffb1 Add word "Euler's number" to Math::E docs
When searching for this constant, I landed on the correct page https://ruby-doc.org/core-2.6.4/Math.html however I was using CMD+f to search for "Euler" and did not find it. If we add the full name for this constant then it will be easier to search for and find.

shyouhei 3ca0948f68 INFINITY is float. That of double is HUGE_VAL.
It seems HUGE_VAL is already used. Why not eliminate INTINITY.
NAN is also float. That of double is called nan(). This is also
fixed.

  a macro) introduced at r55641.
