This patch should fix an error with the way memory reallocation was
used, which resulted in "realloc(): invalid next size".
It is not completely clear to me as to what caused this problem, but
apparently one can not depend handing a pointer to "realloc(3)" and
expect that it still works afterwards, but one should/must use the one
returned by the function.
Also this patch replaces a variable which was used to remember the
position in the array by just computing that from the current values.

the multiplier function always tried to extract a number, even if the result
is a string because of using a mib.
before:
```
./check_snmp -H hostname -P2c -c public -o IF-MIB::ifAdminStatus.11466 -vvv -r 0
/usr/bin/snmpget -Le -t 10 -r 5 -m ALL -v 2c [context] [authpriv] 10.0.13.11:161 IF-MIB::ifAdminStatus.11466
IF-MIB::ifAdminStatus.11466 = INTEGER: up(1)
Processing oid 1 (line 1)
oidname: IF-MIB::ifAdminStatus.11466
response: = INTEGER: up(1)
SNMP OK - 0 | IF-MIB::ifAdminStatus.11466=0;;
```
the regexp 0 matches, even if the actual result is "up(1)".
after this patch:
```
./check_snmp -H hostname -P2c -c public -o IF-MIB::ifAdminStatus.11466 -vvv -r 0
/usr/bin/snmpget -Le -t 10 -r 5 -m ALL -v 2c [context] [authpriv] 10.0.13.11:161 IF-MIB::ifAdminStatus.11466
IF-MIB::ifAdminStatus.11466 = INTEGER: up(1)
Processing oid 1 (line 1)
oidname: IF-MIB::ifAdminStatus.11466
response: = INTEGER: up(1)
SNMP CRITICAL - *up(1)* |
```

check_curl fails on large pages:
HTTP CRITICAL - Invalid HTTP response received from host on port 5080: cURL returned 23 - Failure writing output to destination
for example trying to run check_curl on the test from #1822
I guess the idea is to double the buffer size each time it is to small. But the code
exponentially grows the buffer size which works well 2-3 times, but then fails.

The current implementation becomes exponentially slower with growing
response size.

Fix test plan when run with NP_INTERNET_ACCESS=no, where the correct
number of steps must be skipped.
Caused by a removed test in 65fc7064295ac70d1388fa4db4d4d2cddd531e24.

* If server_address is an IPv6 address surround it with brackets
* If the message is too short, we should not have an underflow
* Add simple conditional test case available if IPv6 is
|
|
* Remove superflous CRLF in HTTP-Requests in check_http

The problem is that check_pgsql validates the Database name and has different assumptions
that postgres itself.
I fail to see a reason to validate the database name here. Postgres'es API should
do this - So i would suggest a fix like this by removing is_pg_dbname alltogether.

There a situations where UNKNOWN or CRITICAL services are not
wanted when a filesystem is missing, a regex does not match or the
filesystem is inaccessible on a system.
This new option helps to have the service in state OK.

//test.server.com/folder
Referenced redirect of the format //www.server.com/folder would result
in check_http trying to contact http://hostname:80//www.server.com/folder
instead of http://www.server.com/folder. Referenced redirect of this format
is listed in rfc3986 ( https://tools.ietf.org/html/rfc3986 ). It should
work as expected now.
