Modules:  Add mod_setsymtab to set global symtol table once.  Now we can remove symbol table parameters from the insmod call.  This will make implementing an NSH insmod command much easier

OS modules:  Add basic procfs support.  A module registry that will eventually be used to support lsmod

Move module support from binfmt/ to sched/ so that it can be configured and built independently from binfmt features

binfmt/libmodule:  Add support for kernel modules.  Initial commit is  just the ELF module support with name changes

Refresh all configurations that have Telnetd enabled; those configurations now also need the telnet driver

Top-level Makefiles: Check if CONFIG_ARCH_BOARD_CUSTOM_DIR_RELPATH is enabled

drivers/net/telnet.c:  Now works like the loop device.  A new interface called telnet_initialize() registers a telnet session "factory" device at /dev/telnet.  Via ioctl, the factory device can create instances of the telnet character devices at /dev/telnetN to support Telnet sessions.
