- Moved out creating StringBuffers in loops and instead create them outside and just reset the buffer if it was not allocated (to avoid a possible malloc/free for every entry) Other things related to set_buffer_if_not_allocated() - Changed Valuebuffer to not call set_buffer_if_not_allocated() when it is created. - Fixed geometry functions to reset string length before calling String::reserve(). This is because one should not access length() of an undefined. - Added Item_func_conv_charset::save_in_field() as the item is using str_value to store cached values, which conflicts with Item::save_str_in_field(). - Changed Item_proc_string to not store the string value in sql_string as this clashes with Item::save_str_in_field(). - Locally store value of full_name_cstring() in analyse::end_of_records() as Item::save_str_in_field() may overwrite it. - Marked some strings as set_thread_specific() - Added String::free_buffer() to be used internally in String functions to just free the buffer but not reset other String values. - Fixed uses_buffer_owned_by() to check for allocated length instead of strlength, which could be marked MEM_UNDEFINED().
