InitRD & KMod syscalls

[vercas]

A set of syscalls is required to allow the initialization application to inspect the InitRD, and to deal with kernel modules.

• InitRdList - Lists all entries in a directory within the InitRD.
• InitRdFind - Attempts to get a handle on an item within the InitRD.
• InitRdGetInfo - Retrieves information about the given InitRD item from its handle.
• InitRdLoad - Loads the given InitRD item from its handle into the specified chunk of memory.
• KmodList - Lists loaded kernel modules (as handles).
• KmodGetInfo - Gets information about the given kernel module by handle.
• KmodLoad - Loads a given kernel module (from either an InitRD item handle or a chunk of memory), returns handle.
• KmodUnload - Unloads the given kernel module by handle.
