* Name: builtin_setlist
*
* Description:
* Saves the user-space list of built-in applications for use by BINFS in
* protected mode. Normally this is small set of globals provided by
* user-space logic. It provides name-value pairs for associating
* built-in application names with user-space entry point addresses.
* These globals are only needed for use by BINFS which executes built-in
* applications from kernel-space in PROTECTED mode. In the FLAT build,
* the user space globals are readily available. (BINFS is not
* supportable in KERNEL mode since user-space address have no general
* meaning that configuration).
*
* Input Parameters:
* builtins - The list of built-in functions. Each entry is a name-value
* pair that maps a built-in function name to its user-space
* entry point address.
* count - The number of name-value pairs in the built-in list.
*
* Returned Value:
* None
