XCodeDependency: Clarify that Xcode.app is needed

Clarify the error message arising from XCodeDependency so that users know
XCode.app is needed and that just installing the CLT does not count as
"installing XCode".
XCodeDependency: Things that call xcodebuild

Anything that calls `xcodebuild` needs a full install of XCode.app. Two
formulae ommitted from this patch:

  - `fuse4x_kext`: Everything that depends on the kernel extension can be
    compiled by the CLT. Therefore, this formula is bottled and XCode is only
    needed to produce the bottles.

  - `graphviz`: XCode is only used to create GraphViz.app which is not used by
    any of the things which depend on `graphviz`. Creating the app should be
    made into an option.
graphviz: Use options DSL
graphviz: Building GraphViz.app is now optional

Building GraphViz.app requires a full install of XCode.app so building it
by default breaks the installation for users who only install the Command Line
Tools.

Fixes #14431.
cairo: depend on glib unless we don't want X.
dia: remove; good binary package available.

Mac OS X binaries here: http://dia-installer.de/download/macosx.html
synergy: remove as broken; binaries available.

The new betas are stable, maintained and properly packaged.
ctail: fix build on ML due to apr-1-config

Ctail and Serf suffer from the ML bug where `apr-1-config --cpp`
returns a non-existent path. Serf is fixed. Add the same changes
to Ctail where `CPP` and `APR_LIBTOOL` get sane values, where
there are new deps on `libtool` and `automake`, and where
XCode-only installs get help finding the apr includes. Also
change from manual compile commands into using their Makefile
because it works correctly and was doing the same thing basically.
By using the `Makefile` we also get all the `apr-1-config --libs`
brought in which may be different for SL vs L vs ML.

cf. #13891
Fixes #14313

Fixed: libgphoto2 requires libltdl from libtool

Added libtool as a dependency for libgphoto2.
When building libgphoto2's configure script reported that it could not
link against libltdl which is included in libtool.

Closes #14450.
