Non-string values in a cache is supposed to choose one from them.
Due to the change of da1c9f7a, there was a regression on scoring for
matching functions. So reverting the behavior for evaluating non-string
values to the previous one.

Sometimes fonts has multiple values in family and sub-family in order to unify
other variants into one. they basically make difference in sub-family though,
they also still have standalone family and sub-family. in that case, sub-family is
likely to be Regular.
fontconfig couldn't recognize the difference between :family=Foo:style=Regular
and :family=Foo Caption:style=Regular for example because fontconfig didn't
give different score on matching result for the position of multiple values in
a cache.
Thus, when querying a font like :family=Foo:style=Regular may results
:family=Foo Caption:style=Regular. (see the test case for more details)
To fix this situation, giving different score according to the position
of multiple values in a cache as well as the position of multiple values
in a query.

Any early out checks must give the same answer as FcConfigCompareValue.
An accelerator was added for family names which treated all ops as if
they were FcOpEqual, giving the wrong answer for other non-equivalent ops
(for example FcOpContains or FcOpNotEqual).
This adds a test which passes before the accelerator was introduced,
fails after, and will pass again after !142 lands. This tests the all
not_eq case.
The test-conf test requires libjson-c to be available in order to be
built. However, there has been no user indication that additional tests
could be built if the json-c development files were available.
Continue to not build test-conf if json-c is not available, but do run
the test harness. The test harness is updated to SKIP the test if the
test-conf binary is unavailable.
This causes a failure when evaluating $OSTYPE on systems which do not
set that variable (everything but Msys/MinGW)
