Also did a bit of cleanup.
interpreter.py: There’s a catch all except clause at the line 1928, it didn’t give the user any information whatsoever about the exception it caught. Now it at least print it to the log as a warning.
Just checking that the version retrieved from the pkg-config file
matches is not enough. It's nearly tautological since it just checks
that we aren't returning garbage in dep.version(). Instead, check in the
test executable that the pkg-config version retrieved matches the
ZLIB_VERSION exported by zlib.
Also don't require zlib 1.2.8 since RHEL (EPEL) 7 still has 1.2.7 and we
don't really need 1.2.8 anyway.
When generating the .gir file we need g-ir-scanner to link the
introspector binary against the right dependencies, for that
we used to use the --library option but this has a special meaning
and the libs passed in there end up being the ones in the .gir file
itself, which is not what we want.
A new --extra-library option is beeing added in goject-introspection
(https://bugzilla.gnome.org/show_bug.cgi?id=774625) to handle our use case
(ie. not using libtool which allows g-ir-scanner to know about those)
and we should make use of it.
Closes#981
Otherwise trying to introspect tests might lead to:

Sometimes we want to restrict the acceptable versions to a list of
versions, or a smallest-version + largest-version, or both. For
instance, GStreamer's opencv plugin is only compatible with
3.1.0 >= opencv >= 2.3.0
We originally skipped on Windows for the same reason, and now we need to
do that for EPEL 7 and F23 which ship pkg-config 0.28 which doesn't have
--validate.
Closes#1129
This approach is locale-independent and more correct. For instance, this
will work with UTF-16 while the previous approach with binary comparison
would not.
This also removes the need for doing an explicit decode to utf-8 which
is lossy and can fail by yielding no output at all.
We want compiler check arguments (-O0, -fpermissive, etc) to override
all other arguments, and we want extra_args passed in by the build file
to always override everything.
To do this properly, we must split include arguments out, append them
first, append all other arguments as usual, and then append the rest.
As part of this, we also add the compiler check flags to the
cc.compiles() and cc.links() helper functions since they also most
likely need them.
Also includes a unit test for all this.
Many frameworks, such as glib, provide translation functions and
functions that take format strings. As such every application using
these must duplicate the gettext arguments to function properly.
This reduces that duplication and improves correctness so they are
not left out.
