Bug#31891 Meaningful stack trace
On crashes generate a user-friendly resolved and demangled stack
trace when libc provides the necessary functions (newer libc on i386,
x86_64, powerpc, ia64, alpha and s390). Otherwise print a numeric
stack trace as before, relying on resolve_stack_dump utility.
configure.in:
Add check for backtrace headers, backtrace functions and if
__cxa_demangle (libstdc++) is available at link time.
sql/mysqld.cc:
Print the value of the THD::killed variable when dumping. In
some circumstances knowing if the thread was killed makes
debugging easier.
sql/stacktrace.c:
Use the glibc backtrace function when available and demangle
C++ function names if the __cxa_demangle function is available.
sql/stacktrace.h:
Locally export and wrap in C linkage the C++ function __cxa_demangle
if available.
