src: port setclientmode code to C

Implement most of the code from the script setclientmode into
ogServer to improve error handling and logs.

Use a reduced version legacy script to replace the contents of
the base PXE template. This file is now called updategrubprofile.
Add updategrubprofile to the new extras/ folder.

Create BIOS and UEFI files for PXE boot configuration. Each file
is located in a different directory and requires a different name
pattern.

-BIOS-
File format:
/opt/opengnsys/tftpboot/menu.lst/01-XX-XX-XX-XX-XX-XX

Template dir:
/opt/opengnsys/tftpboot/menu.lst/templates/

-UEFI-
File format:
/opt/opengnsys/tftpboot/grub/01-xx:xx:xx:xx:xx:xx

Template dir:
/opt/opengnsys/tftpboot/grub/templates/
