	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.

file.c: fix buffer overflow

2013-11-26T07:30:37+00:00

* file.c (rb_readlink): fix buffer overflow on a long symlink. since
  rb_str_modify_expand() expands from its length but not its capacity,
  need to set the length properly for each expansion.

* file.c (GetLastError): already defined in windows.h on nowadays
  cygwin, and caused the confliction with the system provided
  definition on cygwin64.  by @kou1okada [Fixes GH-433].

* add RUBY_TYPED_FREE_IMMEDIATELY to data types which only use

2013-10-29T11:16:54+00:00

  safe functions during garbage collection such as xfree().
  On default, T_DATA objects are freed at same points as fianlizers.
  This approach protects issues such as reported by [ruby-dev:35578].
  However, freeing T_DATA objects immediately helps heap usage.
  Most of T_DATA (in other words, most of dfree functions) are safe.
  However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
  for safety.
