libos (arch/lib) emulates a sysctl-like interface by a function call of
userspace by enumerating sysctl tree from sysctl_table_root. It requires
to be publicly accessible to this symbol and related functions.

add SLIB allocator for arch/lib (CONFIG_LIB) to wrap kmalloc and co.
This will bring user's own allocator of libos: malloc(3) etc.

timer related (internal) functions such as add_timer(),
do_gettimeofday() of kernel are trivially reimplemented
for libos. these eventually call the functions registered by lib_init()
API.
