Add command line options -4 and -6 (--use-ipv4 and
--use-ipv6) to check_dig.
Effectively this adds no new functionality, just a
shortcut for:
check_dig -A "-4"
check_dig -A "-6"
Needed for using check_dig with the check_v46 wrapper
(see e.g.
https://gitorious.org/nagios-monitoring-tools/nagios-monitoring-tools/blobs/master/check_v46)
which requires -4/-6 command line option support.
The memory allocation mixed up number of bytes with number of pointers,
meaning as soon as we'd reach (on 64 bit systems) the second argument,
we'd start writing it outside of our allocated memory.
Normally, this isn't too visible, but as soon as you (again, on my 64
bit system) reach argument number 8, you get a segfault. It is easily
reproducible with:
check_snmp -o '' -l '' -o '' -l '' -o '' -l '' -o '' -l '' \
-o '' -l '' -o '' -l '' -o '' -l '' -o '' -l ''
This patch allocates the proper amount of memory, to fix the issue.

My original patch was based on the online version which was apparently out of date.
In the meantime someone changed the description of example7 instead of the example. I think this is better because
otherwise example 6 and 7 are basically the same.
The last example in the table contradicted the previous example. Surely
it's purpose was to showcase the @ behaviour to invert threshold, but the
@ sign was missing.
I also clarified the description to the second last example so it is in same
style as the others.
This adds support for @<range> and makes stuff a bit simpler by removing code
duplications.
Note: Previously, the compatibility code for 'check_procs <warn> <max>'
accepted something like 'check_procs -w 10:-1 -c 10:-1 20 50' as well
(treating it as if '-w 10:20 -c 10:50' was specified). This is no longer the
case ... additional arguments are only used as warn/crit thresholds in case
-w/-c is not specified at all.
The initial file was created in the user's home and later tested in the
doc directory. Instead, just rsync if the file is missing.
Also add some temporary files to gitignore/make clean
Dying without a hint of what went wrong is just plain annoying. With
this patch we at least get a hint.
While at it, we fix the string offset so the output we're interested
in doesn't keep the equal sign that snmpget prints.

Since the state patch introduction, we've been freeing uninitialized
memory in lib/utils_base.c::np_cleanup(), which caused coredumps
with check_snmp when illegal threshold ranges (for example) were
passed, or when we called 'die' without having read any state.
This patch fixes it by replacing the malloc() calls in there (all of
them, since using malloc() is almost always an error) with calloc().
malloc() either doesn't initialize the memory at all, or taints it
with a special marker so it can tell us when we're free()'ing memory
that hasn't been initialized. calloc() explicitly initializes the
allocated memory to nul bytes, which is a zero-cost operation when
we get the memory from the kernel (which alread does that) and almost
always desirable everywhere else.

Once upon a time, check_snmp used to accept inverse ranges in the
format of '2:1' to mean "alert if value is inside this range".
Since commit 7cb3ae0933, ranges such
as those have instead triggered the error "Range format incorrect"
and resulted in an UNKNOWN warning state. This patch attempts to
fix the situation so that the old-style ranges continues to mean
exactly what the once did and people with lots of snmp checks can
avoid a bazillion false positives from their environments.

A recent update removed the declarations for a couple variables in
check_smtp.c that are still being used, which caused a failure
in the compilation of check_smtp.c. This commit restores those variable
declarations so the check_smtp.c will again compile.
Earlier versions of check_smtp generated an (invalid) "MAIL FROM"
command without arguments by default. These days, a "MAIL FROM" command
is only sent if the --from option is specified.
This commit removes a comment which explains the old behaviour, and it
updates a variable name accordingly.

Apparently some people used -f '<nagios@example.com>' to work around
the bug I just fixed in the MAIL FROM: command generation. Although
the resulting command wasn't RFC-compliant, it was working with some
MTAs, so let's continue to support this syntax now that we generate
RFC-compliant commands.

Every version of the SMTP standard (from RFC 821 to the current RFC
5321) requires the address following MAIL FROM: to follow the colon
immediately (with no space) and to be surrounded by angle brackets.
