cleanup: Remove ports depending on expired lang/gcc6-aux

Keep ports-mgmt/synth and dependencies (including lang/gcc6-aux itself)
for now as synth is the only Ada port still maintained and might be
somewhat high-profile.

Removed ports:

cad/ghdl
databases/adabase
databases/apq
databases/apq-mysql
databases/apq-odbc
databases/apq-pgsql

devel/ahven: Improve symbolic traceback functionality

Rather than show the lengthy and not helpful trace of the Ahven
Framework when a symbolic trace is shown, detect the start of this
infrastructure trace and truncate it there.  This helps debugging
greatly by removing a lot of noise.

devel/ahven: Modify to add symbolic tracing.

The author, Tero Koskine, intends for ahven to be compiler agnostic,
and therefore can't use GNAT-specific functionality like
GNAT.Traceback.Symbolic.  However, there is only one brand of Ada
compiler in ports, GNAT, so we can take advantage of it.

This change adds a default option to alter the exception handling to
trace through the symbols to display files and line numbers of each
frame on the stack.  Declining the option builds Ahven without the
modification and allows Ahven to be used on non-GNAT compilers (assuming
you can find one on FreeBSD.)
