Harmonize functions to parse epsg codes from WFS GetFeature requests and support different variants for expressing epsg codes.
Support for CRS URI format http://www.openis.net/gml/srs/epsg.xml#xxx as specified in WFS
Segfault resolved when parsing srsName in WFS spatial filter.
updated msautotest to latest master revision
add mspython tests to Makefile.autotest
fix mspython-testcase target
WFS paging parameter startIndex changed to base on 0 (0 is the first feature). See #4180 for external references.
Replace `strlcpy` with `strncpy` in `msIO_stripStdoutBufferContentType()`

The use of `strlcpy` was producing *uninitialised value* errors in
valgrind.  It appears this was due to the fact that `strlcpy` expects
the source string to be null terminated which is not always the case
in this context.

Fix a memory leak in `freeClass()` exposed by valgrind's memcheck

In `msGrowClassLabels()` memory is assigned to
`class->labels[class->numlabels]` but was only freed to
`class->numstyles-1` in `freeClass()`.  This fix ensures the last
label is freed.
Revert "Fix a memory leak in `freeClass()` exposed by ... memcheck"

This reverts commit 4b90c2404f4b3209f491ab84780f735fba4a119d which as
discussed in issue #4685 is not a valid solution.
