takes care can be dropped from configure.am.

various portability autotools directives which where part of this

Fix to a very severe bug. In cases when IP addresses in lease file had
a range of using highest bit, e.g. signed int minus, the sort caused
high ranges to be counted first and low ranges skipped. The usual case
when this happen was when ranges contained 10.0.0.0/8 addresses
together with addresses greater than 128.0.0.0/32.

The problem is, that you simply count all lease occurrences in
dhcpd.leases, but only the last ones for each ip address are
valid. The lease file is more like a logfile of what has been
done, than a real database. To fix the counting issue, I'm using
a single hash (from uthash.h [1]) for the counting. This way
only the last lease entry for each IP gets into my counting
structure.
When you remove the duplicates in prepare_data(), you don't have
the information anymore, if the active lease entry or the free
lease entry came last. Simply deleting each ip from the touches
array, that is already in the leases array, gives you a big
chance to count wrong. Another way of fixing this would be to
not only store the ips in your arrays, but a structure containing
the ip and a global lease entry counter. Then you could delete
all entries except for the latest.

When { is wrote together with a word, such as
pool{
range 10.0.0.100 100.0.0.200;
range ..
the parser ignored first range, resulting it to disappear from analysis.

The script is not maintained, but perhaps nice to have a
reference how the IP sorting & range matching was done in demo
version. Actually more proper version number would have been 0.x
but it was not.

This patch adds consistant underlining to arguments, and unifies
spacing. Also the wording for -L is made much better, it's been
common to hear the manual was unclear about that option.

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.
