At least some versions of GCC appear to take any -Wno-foo option
without error even if that option is not supported.  But they will
error out if -Wno-error=foo is used.  This sounds like a GCC bug, but
we'll work around it and test for the feature both ways.

FS-6850 #resolve

With this commit, passing -Q to fs_cli will cause fs_cli to not load
or save the command history file (~/.fs_cli_history).  This can be
useful e.g. on read-only systems.

This can also be set in the fs_cli configuration file with the option
`no-history-file`.

The debian/control-modules file is a comprehensive list of modules,
not a list of modules which are built.  Our build tools verify the
file is comprehensive, so modules can't be removed from here unless
we're taking them out of tree.

Partially revert "don't package mod_cluechoo and don't build/load by default"
This partially reverts commit e02e41a5.

To work correctly in a multi-threaded environment, curl needs to be
used with CURLOPT_NOSIGNAL set to 1.  If it's left at zero, the
default, then curl will use signals to deal with timeouts which will
often result in a crash.

Markdown treats this as an H1 otherwise.

This makes it visually clearer what the reader is looking at and
highlights that we want a real name as the author name.

We want to highlight that lines are hard wrapped in a commit message,
and using the typical Markdown blockquote syntax fails to achieve
that.

add buffer_seconds param to shout filehandles to override the original default of 1 and remove previous code to attempt to buffer several seconds of audio in the open routine.  Any experiencing jittery playback from slow shout destinations should add {buffer_seconds=N} to the file path to increase the amount of time allotted for buffering when no audio is discovered on the wire

when video floor is locked by a member, changing audio floor on del_member
will cause the video floor lock cleared unexpectedly, this commit fixes that.
