Fix Bug 18060: Assertion failure (JSLock not held) beneath JSCallbackObject<Base>::toString

<​http://bugs.webkit.org/show_bug.cgi?id=18060>

Reviewed by Geoff Garen.

Bug fix:

  • API/JSCallbackObjectFunctions.h: (KJS::JSCallbackObject<Base>::toString): Make the DropAllLocks instance only be in scope while calling convertToType.

Test:

  • API/testapi.c: (MyObject_convertToType): Implement type conversion to string.
  • API/testapi.js: Add a test for type conversion to string.
  • Property svn:eol-style set to native
