dahdi-perl: Freepbxdb config generator

Use 'dahdi_genconf freepbxdb' to generate the required astdb entries
for Asterisk to use the extensions generated by dahdi_genconf. Requires
asterisk to be running.

This module is intended for testing as it bypasses standard FreePBX
functions only and hence may not work properly with Freepbx.

+=head1 NAME
+
+freepbxdb - Generate astdb configuration required by FreePBX
+
+=head1 SYNOPSIS
+
+ use Dahdi::Config::Gen::Freepbxdb;
+
+ my $cfg = new Dahdi::Config::Gen::Freepbxdb(\%global_config, \%genopts);
+ $cfg->generate(@span_list);
+
+=head1 DESCRIPTION
+
+Updates the Asterisk DB entries for FXS channels detected. Requires
+Asterisk running.
+
+The configuration generated here bypasses FreePBX's standard configuration
+and allows using a simple dialplan snippet such as:
+
+  [from-internal-custom](+)
+  exten => _4XXX,1,Dial(DAHDI/${EXTEN:1})
+
+This may come in handy in testing. At least until FreePBX will provide a
+simple automated interface to do the same.
+
