* configure.ac: Test for header file <ucontext.h> (for use in
signal processing).
* sigevent.c: (trap_default_signals) Use the SA_SIGINFO flag to
pass additional siginfo_t and ucontext_t arguments to core_handler
and exit_handler.
(core_handler,exit_handler) Now invoked with 3 arguments (using
SA_SIGINFO). Pass additional info to zlog_signal.
(program_counter) New function to find program counter in ucontext_t,
needs to be enhanced to support more platforms (currently works only
on Linux/x86).
* log.h: Change the zlog_signal prototype to add new arguments
siginfo_t * and program_counter.
* log.c: (zlog_signal) Add new arguments siginfo and program_counter.
Include si_addr and program counter (if non-NULL) in message.
And remove #ifdef HAVE_GLIBC_BACKTRACE around hex_append, since
that is now used to render the si_addr and PC pointers.

* configure.ac: If configure is invoked with --enable-snmp, but
the configure script is unable to find SNMP support on the platform,
then configure should give an error message and exit.
