rikardfalkeborn 613dc19b68 #4241: Check for address of single character passed as string (#1381) 
* #4241: Check for address of single character passed as string

Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.

Since ValueFlow currently does not handle global constants (see #7597),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.

Remove comment in docs saying strz is unused.

* Change asdf to Hello world

* Add test of address to first element in string

* Add error reporting function to getErrorMessages

* Fix strings in test

rikardfalkeborn 0e639ea7c9 runtest.sh: Bugfix cfg dir when run in test/cfg (#1311) 
Commit 5cc8da2db4 introduced syntax checking of xml-files. This broke
running the file directly in the test/cfg folder since it assumed the
config files to check were located in cfg in the current working
directory. Fix this by adding a variable that holds the correct path.

Sebastian 038064436d std.cfg: Fix minsize configuration for vsprintf (#1188) 
minsize with argvalue for arg 2 which is a char pointer makes no sense.
Changing it to minsize with strlen for arg 2 results in false positives
(and i think false negatives too).
In std.c a test with a valid vsprintf usage is added that would result
in a FP when minsize with strlen for arg 2 would be used.

windows library: Add config for some Local* functions (#1139) 
Add configuration and tests for LocalAlloc, LocalFree and some other
Local* functions.
LocalReAlloc is currently not configured as an alloc/dealloc function
(like realloc is not configured in std.cfg), i am not sure how to
correctly configure it.
