solaris after a crash
This patch adds a Solaris-specific version of
print_stacktrace() which uses printstack(2), available on all
Solaris versions since Solaris 9. (While Solaris 11 adds
support for the glibc functions backtrace_*() as of
PSARC/2007/162, printstack() is used for consistency over all
Solaris versions.)
The symbol names are mangled, so use of c++filt may be
required as described in the MySQL documentation.
sql/stacktrace.c:
Added Solaris-specific print_stacktrace().
