--
configure.ac checks for the existence of libssh before trying to build sshdump,
ciscodump, and others, but they rely on API functions that are only present in
libssh-0.6.0 and greater. (Not in libssh-0.5.5 or even in 0.6.0rc1.)
libssh-0.5.5 is pretty old, but it is what comes with RHEL/CentOS 6.x.

sshdump.c: In function ‘run_ssh_command’:
sshdump.c:147: error: implicit declaration of function ‘ssh_options_get_port’
make[2]: *** [sshdump.o] Error 1
make[2]: Leaving directory `/home/johnthac/git/wireshark/extcap'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/johnthac/git/wireshark'
make: *** [all] Error 2

ciscodump.c: In function ‘read_output_bytes’:
ciscodump.c:142: error: implicit declaration of function
‘ssh_channel_read_timeout’
make[2]: *** [ciscodump.o] Error 1
make[2]: Leaving directory `/home/johnthac/git/wireshark/extcap'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/johnthac/git/wireshark'
make: *** [all] Error 2

The AC_WIRESHARK_LIBSSH_CHECK should be rewritten to look for these functions
before trying to automatically build these (perhaps replace with
PKG_CHECK_MODULES, since libssh does come with pkg-config information).
Obviously there's a workaround to individually disable building the two dump
programs.
