- Since Genode::strncpy is not 100% compatible with the POSIX
strncpy function, better use a distinct name.
- Remove bogus return value from the function, easing the potential
enforcement of mandatory return-value checks later.
Fixes#3752
1) The loop for determining the line length read from a character offset
before checking whether the offset is smaller than the given string
length. This could have caused access outside the string buffer.
2) The routine for determining the line length first seeked for the
offset of the last real character of the line and than added one for
getting the length but only if the following character was '\n'. This
has to be done for any other line-terminating character too. The only
case where you don't want to do this is when the end of the whole
string is reached.
Issue #2967
Since the dynamic linker depends on the XML utils and we plan to replace
the ancient 'Arg_string' with XML, it is time to move the 'Xml_node' and
'Xml_generator' to base/include.
