In case we are reading the rules from a file we need to reset the
file descriptor to the original position when calling erec_print.
This was not the case in previous code and was leading to valid
file to be seen as invalid when treated in debug mode.

A static array was used to read data and to write information in
it without checking the limit of the array. The result was a buffer
overflow when the line was longer than 1024.
This patch now uses a allocated buffer to avoid the problem.

Use stdio's vasprintf instead of gmp_vasprintf which is not part
of the mini-gmp function subset. Furthermore convert the only
gmp-specific user and allow the compiler to verify format-strings.

1) This removes former Makefiles and install-sh (which is now
automagically imported via autoreconf).
Makefile.defs.in
Makefile.in
Makefile.rules.in
src/Makefile.in
install-sh (now automagically imported via autoreconf).
2) CFLAGS are left almost same, they are integrated into Make_global.am.
Use AM_CPPFLAGS to set the CFLAGS set by pkgconfig.
3) Add m4 directory to the tree which only contains the .gitignore
file. Update .gitignore file to skip autogenerated files.
4) include <config.h> whenever required.
5) Minor adjustments to scanner.l and parser_bison.y to compile cleanly
with autotools.
6) Add %option outfile=lex.yy.c to scanner.l, otherwise I hit this error
here:
gcc -DHAVE_CONFIG_H -I. -I.. -I../include -DDEFAULT_INCLUDE_PATH="\"/usr/etc\"" -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations -Wdeclaration-after-statement -Wsign-compare -Winit-self -Wformat-nonliteral -Wformat-security -Wmissing-format-attribute -Wcast-align -Wundef -Wbad-function-cast -g -O2 -MT mnl.o -MD -MP -MF $depbase.Tpo -c -o mnl.o mnl.c &&\
mv -f $depbase.Tpo $depbase.Po
/bin/sh ../build-aux/ylwrap scanner.l lex.yy.c scanner.c -- flex

7) Add Makefile.am for include/ (contributed by Giorgio Dal Molin).
The doc/ and files/ conversion to automake will come in follow up
patches but 'make distcheck' already works.

For errors starting at column 0, we must not subtract 1 to avoid underflow.

This patch migrates nft to use the libnftables library, that is used
by the iptables over nftables compat utility as well. Most of the
conversion was pretty straight forward. Some small significant changes
happened in the handling of set element and immediate data abstraction
that libnl provides. libnftables is a bit more granular since it splits
the struct nfnl_nft_data into three attributes: verdict, chain and plain
data (used in maps).
I have added a new file src/mnl.c that contains the low level netlink
communication that now resides in nftables source tree instead of
the library. This should help to implement the batching support using
libmnl in follow up patches.
I also spent some significant amount of time running my tests to make
sure that we don't increase the number of bugs that we already have
(I plan to provide a list of those that I have detected and diagnosed,
so anyone else can help us to fix them).
As a side effect, this change should also prepare the ground for
JSON and XML support anytime soon.
