On Debian Buster gcc ((Debian 8.2.0-8) 8.2.0) was throwing the following
warning:

Turns out I didn't have the readline-dev package installed. As the have_rl
variable is wrapped in CPP macros, it indeed is not used when readline is not
available.
As some content was getting dated, refresh the content of the various
manual pages and while doing so, update the pages to conform more
closely to man-pages(7), man(7), and groff_man(7).
Because some rigs lock their front panel when opened for CAT it is
helpful to call rig_close() in rigctld when no clients are
connected. This change does that.
A CTRL+C handler is also added to allow rig_close() to be called
during exit.
on the real rig. In rigctl_parse.c, we make sure that invalid attempts to
so so are mapped on a safe variant.
Second change to netrigctl: drain the input line before sending a new
command, to reach sync again after a timeout.

Fix rigctl and rigctld to not abort on function not available
Change Yaesu detection of FA length to automatic method instead of rig specific
Although there is no reasonable recovery from SIGPIPE we do not want
to terminate the server process, just the client servicing thread. We
do this by setting the disposition for SIGPIPE to ignored, this causes
an EPIPE to be returned from blocked write() and send() calls that end
up trying to send to a broken pipe/socket.
This makes the first non-option argument end getopt_long() parsing
stop rather than shuffling non-option arguments to the end. This is
necessary so that rig/rotator command language arguments can start
with a '-' character and also it enables the '-' pseudo command to
switch to reading commands from stdin work correctly.
The change also make checking for the '-', switch to stdin, command
stricter in that it must be where a command is expected and it must be
a word containing exactly a single '-' character.
Overall this allows the following styles of use:
$ rigctl R -
$ rigctl - <<EOF
>R -
>EOF
R -
$ echo "R -" | rigctl -
R -
$ rigctl -m 1 M CW -1
$ rigctl F 434000000 - <<EOF
>M FM 15000
>f m
>EOF
M FM 15000
f 145000000
m FM
15000
$
as well as the command line interpreter operation where no commands
nor '-' are provided:
$ rigctl
Rig command: R -
Rig command: r
Rptr Shift: -
Rig command: f
Frequency: 145000000
Rig command: m
Mode: FM
Passband: 15000
Rig command: F 434000000
Rig command: f
Frequency: 434000000
Rig command: q

CAT protocols that don't allow direct addressing of VFOs require that
the "other" VFO be queried or set via a select then get/set then
select back to original or swap then get/set then swap again. When
both frequncy and mode need to be set the sequences can be optimized
if a single funciton is avaiable.
This enhancement adds those single functions rig_set_split_freq_mode()
and rig_get_split_freq_mode() with a default impelementation that
calls the individual rig_{get,set}_split_{freq,mode}() functions. Back
ends can choose to implement an optimized version which is used
instead of the default if present.
Using these functions when an optimized implementation is available
allows the TX VFO's frequency and mode to be set in a single operation
with only one VFO exchange or selection either side of the
operation. Many CAT protocols are very efficient when getting or
setting both frequency and mode and some even combine the two in a
single command.
The letters 'K' and 'k' are used for the rigctl short command name for
these functions.
After discussions with Greg N1DAM I have changed the dual stack
support to explicitly allow IPv4 connections mapped to IPv6 for any
AF_INET6 address since BSD as well as Windows defaults this socket
option to on (disallowed).
IPv4 mapped to IPv6 makes sense for Hamlib servers since starting two
servers one for each protocol family (the other option) is not
possible since there is only a single rig/rotator which cannot be
shared between two servers.
As the rigctld and rotctld programs are actually user programs and
installed in ${prefix}/bin, it was erroneous to install the associated
manual pages into the man8 directory. Correct this error going forward
and install them into man1 with the other manual pages.
As Hamlib now restores the rig auto information state (AI) on exit
there is now a need to disable that functionality so that rigctl can
be used to set/reset AI mode on the rig explicitly.
A new public API function 'rig_no_restore_ai()' is also added that
allows any client to disable this auto AI restore functionality if
required. Most clients should do nothing as restoring AI state is a
good thing.
This means that rigctl & rigctld now work with default arguments on a
modern Windows machine with dual stack and localhost being [::1] as
the first interface returned by getaddrinfo().
Try all the interfaces return by DNS lookups to establish a connection
or listening port. Handle Windows network errors correctly so that
meaningful messages are printed.
The rigctl program now accepts IPv6 numeric addresses in the portname
field like [<addr>}:<port> for example the IPv6 loopback on port 4531
would be [::1]:4531.

Richard Sahw, KF5OIM, reported a failure in the C++ test when attempting
to build an RPM package in a clean environment. This patch amends the
LD_LIBRARY_PATH in the generated shell scripts in the c++ and tests
directories.
