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.
Fix msContourGetOption() to be able to parse values where no min/maxscaledenom is specified, e.g. PROCESSING 'CONTOUR_INTERVAL=20' (#4691)
fix crashes on error'd WCS getcoverage requests (#4714)

initialise msWCSGetCoverageMetadata20 to NULL to avoid memory failures
on error
Merge pull request #4714 from tbonfort/b4714-wcs-mem-crash

Fix crashes on failed WCS request (#4714)
autotest update
update submodule
run CI tests quietly
add makefile, build lexer
add parser to makefile
use absolute path to lexer and parser sources
avoid line numbers with flex/bison
use absolute destination for lexer/parser
don't upload coverage for headers
avoid printing curl error if error message has already been set
use msIO for cairo output, correct rsvg version check
only compute coverage for libmapserver and mapserv
typo
re-add build directory to coverage
