Alias Tables RAM Disk Store

If ramdisk is enabled keep a copy of the alias tables to restore at boot time. Otherwise unpredictable behavior may occur due to some aliases not being available when the firewall rules load.

Because alias tables are typically somewhat static, the following strategies are employed to keep write cycles to a minimum for SSD and flash drive type devices friendliness....

Introduce read_global_var:

- Add a new script, read_global_var, that returns the value of any item
contained in global array $g
- Replace all grep and sed magic from shell scripts

Introduce read_xml_tag.sh

Create /usr/local/sbin/read_xml_tag.sh, that will read a xml tag from
config file using xmllint. Replace all direct read using cat, grep, sed,
... by this script

Consider globals_override.inc and replace hard coded pfSense string by product_name

Move main pfSense content to src/
