Subject: [PATCH] Fix heap overflow in `iniparser_dumpsection_ini()`
...reported in #177
As suggested by the issue reporter this is fixed by returning from
`iniparser_dumpsection_ini()` in case the length of the passed section name
of dictionary to dump was bigger than the size of the internal buffer used
to copy this string to.
