George Joseph 41eab5b3b8 backtrace: Refactor ast_bt_get_symbols so it doesn't crash ... We've been seeing crashes in libbfd when we attempt to generate a stack trace from multiple threads. It turns out that libbfd is NOT thread-safe. It can cache the bfd structure and give it to multiple threads without protecting itself. To get around this, we've added a global mutex around the bfd functions and also have refactored the use of those functions to be more efficient and to provide more information about inlined functions. Also added a few more tests to test_pbx.c. One just calls ast_assert() and the other calls ast_log_backtrace(). Neither are run by default. WARNING: This change necessitated changing the return value of ast_bt_get_symbols() from an array of strings to a VECTOR of strings. However, the use of this function outside Asterisk is not likely.
