Some I/O implementations (e.g. mISDN) need this information to correctly
set up the port configuration. In FreeTDM, the mode of a span has been.
up until now, a part of the signalling module configuration ("node" or "mode"
for libpri and isdn spans), which is parsed _after_ the I/O part of a span
has been initialized. This limitation currently prevents us from using mISDN
in NT mode.
To work around this problem (without adding a lot of new tunk_type values like "E1_NET" etc.),
add a new "trunk_mode" parameter to the span categories in freetdm.conf, which by default
is "CPE" for all trunk types, except "FXS" (which defaults to "NET").
ftmod_misdn uses trunk_type + trunk_mode to correctly choose the d-channel protocol
for a port.
ftmod_libpri uses trunk_mode as a hint for the default "mode" setting.
(NOTE: It will print a warning if trunk_mode and signalling mode do not match.)
All other modules currently ignore the value of trunk_mode.
Example freetdm.conf snippet for a mISDN span in NET/NT mode
(using a HFC-S USB dongle):
[span misdn MBRI_1]
trunk_type => BRI_PTMP
trunk_mode => NET
b-channel => HFC-S_USB.1:1-2
d-channel => HFC-S_USB.1:3

Portability fix for uClibc and other (linux) environments that lack execinfo.h.
ftdm_backtrace_walk() and related return FTDM_NOTIMPL and print a message
if backtraces are not available in the current environment.

Use a chain of "else if" statements, drop known_opt completely.
Added bonus: We stop trying to parse option arguments as (possible) options.
Arguments of -u/-g and path options (-conf) now check whether their argument
starts with a dash ('-') and error out in case it does (= next option, not a valid argument).
Use PATH_MAX for everything that stores files / directories.
Use switch_bool_t and SWITCH_TRUE/_FALSE for boolean variables.
Use EXIT_SUCCESS/_FAILURE for exit() calls.
Get rid of excessive indenting (especially in the win32 parts of main()).
NOTE: Win32 parts untested.

Move empty cmdline option string check and "-help/-h/-?" handling to top of loop.
Emit a proper error message for unknown options. (Just displaying the
usage description, but not telling the user which option was wrong, is bad mojo).
