  Fix misuses of asprintf throughout the code.

  This fixes three main issues

  * Change asprintf() uses to ast_asprintf() so that it
  pairs properly with ast_free() and no longer causes
  MALLOC_DEBUG to freak out.

  * When ast_asprintf() fails, set the pointer NULL if
  it will be referenced later.

  * Fix some memory leaks that were spotted while taking
  care of the first two points.
