net: move 6lowpan compression code to separate module
IEEE 802.15.4 and Bluetooth networking stacks share 6lowpan compression
code. Instead of introducing Makefile/Kconfig hacks, build this code as
a separate module referenced from both ieee802154 and bluetooth modules.
This fixes the following build error observed in some kernel
configurations:
net/built-in.o: In function `header_create': 6lowpan.c:(.text+0x166149): undefined reference to `lowpan_header_compress'
net/built-in.o: In function `bt_6lowpan_recv': (.text+0x166b3c): undefined reference to `lowpan_process_data'
