The commit 1e82461875 was
incomplete, and at the end was a cause of off by one miscount.
The reason was bsearch where long int needed to be unsigned.
Weird that the original had work while there where so many type
mismatches.

Remove unnecessary type casting, move .gitignore file contents to
right location, reindent to use Linux coding style, fix few type
mismatches, clean up to help & version output and hint compiler
call to these functions will end program.

After uint32_t fix from 1e82461875
it was good idea to check which headers where needed where. And
generally clean up the includes while doing the check.
There where long and unsigned long used for IPs in use which
caused occasional off by one errors. The word occasional should
be read: pretty much every one with large enough configuration
has been affected.

Ahmed reported he saw the following error with version 2.15 which
is an indication of unusual high number of clients that has been
seen. I am not sure where that happen, but I suspect an airport
or some other 'lots of mobiles getting leases' might be able to
case same situation.
dhcpd-pools: getdata.c:136: parse_leases: Assertion `!(touchesmallocsize < num_touches)' failed.
The problem was quite easy to fix simply getting rid of assert
and putting realloc in place.

The help screen has now same notation as most of the GNU/Linux
utilities, e.g. if a option requires argument it is marked as
option=ARG. That enabled me to use help2man to make small nroff
fixes to manual page to unify it's outlook as well.

This patch is a step a head to make data all structures
completely dynamic. After this the next obvious thing to do is to
make shared networks struct a linked list instead of a list.

This is a test fix after commit
5cbe8d07fb
to see what can be done. Truth is that not much. I could fix how
ranges are allocated, but the fact there is pointers to shared
networks and network names reallocating the memory spaces is not
really going to work. The only way to truly fix this issue is to
create better data structures. As you can expect that is a major
change, and will take some time to implement.

It seems that at least FreeBSD is setting errno when malloc is
successful. There is a change that other operating systems will
do similar things with same, or other system calls, and this will
invalidate the idea of checking errno at exit.

Anders & Thor Eivind reported dhcpd-pools to mess console and
crash at the end of execution. Reason was missing boundary check.
The fix this time is more of less just a increase to max numbers.
That will work ot some extent.
The memory allocations has to be made fully dynamic, but that is
a little bit difficult with the way default.h and parse_config
are working. Basically problem is globals gone crazy & re-entrant
issue with parse function. The true fix to the issue will have to
wait for complete redesign of internals of the command.

The tag v2.14 was probably done without -a option so it was not
recogniced by git describe. To over come this I found easiest to add
--tag to git-version-gen. This change should be reverted after a
