FS-5949 FS-6945 #comment this change should be relevant to both of these issues, please test.  This patch improves the hold parsing and ignores connection address of 0 implying hold when ice is present and disables the auto interpretation by the lower level stack of 0.0.0.0 to automatically imply sendonly to allow FS to decide on its own

One place we said Failed Registration, the other we said Registration Failed, lets try to be consistent.

FS-6954 #resolve #comment technically the new way is more correct but there is no hope for making fax endpoints follow a real spec.  This should take care of it.

The libtool binary used to be contained in the libtool package.  As of
current sid/jessie the libtool package contains everything about
libtool but the libtool binary, and we need to install libtool-bin to
get the libtool binary itself.  Which is to say that Debian decided to
make the libtool package architecture-independent.

Without this commit the FS debian packaging will not build/bootstrap
on sid/jessie.
