This patch allows conference flags to be set dynamically from the
dial plan by either passing them to the conference application in
the +flags{ } string or by setting the "conference_flags" dial plan
variable.

The +flags{ } string is currently used to set *user* flags only.
This patch changes this by allowing the +flags{ } string to contain
conference related flags as well (for example wait_mod). It shouldn't
be a problem to pass both types of flags via +flags{ } as long as
the user and conference flag names are kept unique.

having the same gateway definition bound to the ipv6 and ipv4 external
profiles caused confusion for some new users. Also having a gateway
bound to the internal profile was a bit confusing.

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.

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.

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.
