Add nft_init and nft_exit functions, which calls _init and _exit
functions in main.c file. Remove __init and __exit macro definitions as
libnftables library will be created soon. Rename realm_table_init() and
realm_table_exit() functions to avoid ambiguity as
realm_table_rt_init(), realm_table_meta_init, realm_table_rt_exit() and
realm_table_meta_exit() in rt.c and meta.c files.
Signed-off-by: Varsha Rao <rvarsha016@xxxxxxxxx>

Changes in v1:
- Called all __init functions in nft_init().
Changes in v2:
- Removed unnecessary init functions.
Changes in v3:
- Called __init functions in nft_int().
- Called __exit functions in nft_exit().
- Remove global declaration of struct mnl_socket *nf_sock.
- Modified commit message.
