[SETUPLIB] Add a new module "bldrsup.c" (WIP) where I place all the NT boot loaders (i.e. ntldr, freeldr, and possibly bootmgr in the future) management functions.
So far we only have: - a function FindNTOSBootLoader() that detects the existence of a given boot loader; - a function EnumerateNTOSBootEntries() (and corresponding helpers) that enumerate the different boot entries in the configuration file(s) for a given boot loader, and for each entry, calls a user-provided callback. Only supported at the moment: ntldr and freeldr. Doing that allows me to simplify large portions of the NT-OS detection code so that it becomes more bootloader-agnostic, and this will help me for simplifying some parts of usetup/bootsup.c too, later...
