[ipxe-devel] [ipxe/ipxe] Parse ${name:offset:length} in setting values (#95)

This emulates the bash `${varname:offset:length}` syntax allowing substring manipulation of settings values. It operates during the `fetchf_setting` stage so should work for show, echo and any form of setting substitution.

It extends the existing syntax like name:type:offset:length, e.g.

show smbios/product:string:0:8
show smbios/uuid::0:24
echo ${ifname::3:4}
