Merge all build scripts into one.

• Easy to manage and avoid errors between them
• Create a prestage for FreeBSD build, pfSense sources, ports needed to be installed, and libraries copied from host if needed
• For each customization needed for image use a final stage dir where everything is done
  The last two allow for building world and all kernels needed only once and just using that for each image.
• Each image now will have only one kernel
• Record each operation on its own file under tools/logs
• Understandable logic for image creation allowing easy trouble shooting
• build.sh takes parameters to complement pfsense-build.conf, just run it to get usage
• build_resized_nano.sh is not anymore needed stage it on scripts dir for later removal
• Put protections for parts of the process that cannot be done when doing cross builds
• Also the fcgi test done for php is only valid for versions without php-fpm
