Description
-------

ast_bt_get_symbols can return either an ast_malloc'd or a regular malloc'd list, depending on the value of BETTER_BACKTRACES.

The result was always free'd (not ast_free'd).

This patch:
 - copies the malloc'd list from backtrace_symbols into ast_malloc'd memory,
 - replaces the free's with ast_free's,
 - documents that the ast_bt_get_symbols return value should be freed.

Unsure whether to put it in 1.8, since ast_bt_get_symbols() might be used by an external module.
