Allow setting limit in do_shortcode()

[abelcheung]

Sometimes it is useful to limit the number of shortcode conversion occuring in do_shortcode(), such as preventing overuse of shortcode in untrusted content, or whatever reason. This patch adds a new int parameter to do_shortcode(), which is used as the $limit parameter in preg_replace_callback().

I fail to see how the argument ever gets passed short of manually calling it in a function that overrides the shortcode function in the first place. in such a case, you might as well override this directly in your plugin.

In my plugin's case, it converts shortcode enclosed content into images, but the process is resource hungry and time consuming, so I want to limit number of instances of shortcode parsed, and print others as vanilla text. That's the primary reason of this patch.

Do you mean using a static counter to record number of shortcode instances already parsed?

pretty much exactly, yes.
