By default, continue to use libreadline, but if `--with-cli=linenoise`
is passed to configure, build the linenoise implementation instead.

cli.h includes a forward declaration of struct parser_state which is not
needed. Remove it.

Make CLI code adhere to intended libnftables API by not open coding what
nft_run_cmd_from_buffer() does. This way, nft_run() has no users outside
of src/libnftables.c anymore and therefore can become static.
Since nft_run_cmd_from_buffer() takes care of scanner initialization and
libmnl socket passed to cli_init() is present as nft_ctx field as well,
signature of cli_init() can be reduced to just take nft_ctx pointer as
single argument.
Note that this change introduces two (possibly unwanted) side-effects:
* Input descriptor passed to scanner_push_buffer() is changed from the
CLI-specific one to the one used by nft_run_cmd_from_buffer().
In practice though, this doesn't make a difference: input descriptor
types INDESC_CLI and INDESC_BUFFER are treated equally by erec_print().
Also, scanner_push_buffer() NULLs input descriptor name, so that is not
used at all in latter code.
* Error messages are printed to stderr instead of cli_nft->output.
This could be fixed by introducing an 'error_output' field in nft_ctx
for nft_run_cmd_from_buffer() to use when printing error messages.

Remove cli_display() function, as it is not called anywhere in source
code.

Pass variable cache_initialized and structure list_head as members of
structure nft_cache.
Joint work with Pablo Neira.

This socket should not be global, it is also hidden in many layers of
code. Expose it as function parameters to decouple the netlink socket
handling logic from the command parsing, evaluation and bytecode
generation.

The new structure nft_ctx is meant to be used as a generic container of
context information.
This is a preparatory patch. So at the moment the struct just carry
output_ctx on his path through main.c and cli.c.
Based on original idea from Eric Leblond.

libnftables library will be created soon. So declare numeric_output,
stateless_output, ip2name_output and handle_output as members of
structure output_ctx, instead of global variables. Rename these
variables as following,
numeric_output -> numeric
stateless_output -> stateless
ip2name_output -> ip2name
handle_output -> handle
Also add struct output_ctx *octx as member of struct netlink_ctx.
