As we do not use config.h.in, just define the helper macro
instead.

Pass in ec to vm_opt_newarray_{max,min}. Avoids having to
call GET_EC inside the functions, for better performance.

While here, add a test for Array#min/max being redefined to
test_optimization.rb.

From the documentation of rb_obj_hash:

> Certain core classes such as Integer use built-in hash calculations and
> do not call the #hash method when used as a hash key.

So if you override, say, Integer#hash it won't be used from rb_hash_aref
and similar. This avoids method lookups in many common cases.

This commit uses the same optimization in rb_hash, a method used
internally and in the C API to get the hash value of an object. Usually
this is used to build the hash of an object based on its elements.
Previously it would always do a method lookup for 'hash'.

This is primarily intended to speed up hashing of Arrays and Hashes,
which call rb_hash for each element.

For cyclic objects, it requires to keep a st_table of the partially
initialized objects.

Although `AC_PROG_CC_C99` has been obsolete, `AC_PROG_CC` is not
and the latter is necessary not to make C++ compiler mandatory.

Must not be a bad idea to improve documents.

The vi mode can handle "argument number" before an operator or a motion,
such as, "3x" (equals "xxx"), and "3l" (equals "lll"). In the emacs
mode, GNU Readline can handle argument number with meta key, like
"Meta+3 x" (equals "xxx").

Just like all the other tasks using the `built_gem_path`, the `:build`
task is a prerequisite for this task too.

%v is supposed to be the VMS date, and VMS date format uses an
uppercase month.

Ruby 1.8 used an uppercase month for %v, but the behavior was
changed without explanation in r31672.

Time#strftime still uses an uppercase month for %v, so this change
makes Date#strftime consistent with Time#strftime.
