Subject: [PATCH 01/12] Add back fullname property at scan matching phase
There seems to be a lot of config files using fullname property in the world.
To keep the backward compatibility, fullname property is back to a cache at
the scan matching phase but will be rebuilt once it is done according to family
and style property in the pattern no matter what changes one made in fullname
property during that.

Subject: [PATCH 02/12] Skip leading whitespace in style name.
Found by Clang-Tidy. The intent seems to have been to skip all leading
whitespace in the 'style' string, but instead this loop was an odd
looking no-op. Remove the 'break' from the loop so that it will
continue until end of string or a non-space character is found.

Subject: [PATCH 03/12] Remove abort from FcCompareSize.
There doesn't appear to be a good reason to abort when 'v1' has type
FcTypeRange. If there does turn out to be a good reason for this then it
should be better documented and the code for handling this case removed.
At worst it seems -1 should be returned as it is for other unknown
types. It is possible this is left over debug code from the initial
implementation.

Subject: [PATCH 08/12] Fix wild frees and leak of fs in test-conf.
Reported by AddressSanitizer when running test-conf. The `query`,
`result`, and `result_fs` were not initialized to NULL so could result
in a wild free when first initialized.
The `method` was also not initialized to NULL so comparisons could be
made against random data if it had not yet been assigned.
The outer `fs` was never destroyed, but is also not used, so remove.

Subject: [PATCH 09/12] Always run-test-conf, but skip if not built.
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.

Subject: [PATCH 10/12] Fix test-conf string to integer conversion.
The test-conf build_pattern attempted to convert known constant strings
into integer values. However, it did so by always converting the string
value to an integer if possible and then complaining if the key wasn't
of the expected type. This lead to error messages on "style": "Regular"
since "Regular" was recognized as "weight".
Instead, only attempt conversion from string to integer if the key is
the name of an object which can take an integer type. This eliminates
the spurious non-fatal errors reported when parsing
test-90-synthetic.json.
This also fixes an issue where the created value was given the type of
the object found, but the integer field was assigned. Instead, check
that the object type can take an integer and always set the value type
to integer.
