so far, each library was distributed over a test and (optionally) a
'library' output of a feature. this was conceptually messy and limiting.
so instead, turn libraries into a category of their own.
libraries now support multiple properly separated sources, which makes
overriding them a lot saner. sources can be conditional to accommodate
platform differences.
as an immediate consequence, move (almost) all library references from
the config test projects to the json file.
a few tests were excluded, because they are doing somewhat magic things
that should not be handled in this bulk change:
- freetype: .pri file shared with actual source code
- clock-gettime: -lrt is conditional, and there is a .pri file which is
shared with actual source code
- ipc_posix: -lrt & -lpthread conditional
- iconv: -liconv conditional
the multi-source mechanism is used to make a variety of tests work on
windows, where the library name differs from unix (and sometimes between
build configurations). some tests still needed minor adjustments to
actually work.
on the way, fix up disagreements between manually specified libraries
and pkg-config lines (affecting several xcb-related tests).
