merge revision(s) 46408,46410,46413,46414,46424,46436,46437: [Backport #9934]
string.c: shrink too big buffer
* string.c (rb_str_resize): shrink the buffer even if new length
is same but it is enough smaller than the capacity.
* file.c (expand_path): shrink expanded path which no longer needs
rooms to append. [ruby-core:63114] [Bug #9934]
* string.c (rb_str_resize): should consider the capacity instead
of the old length, as pointed out by nagachika.
* string.c (rb_str_resize): update capa only when buffer get
reallocated.
