This commit removes all qmake-related build-files from the system. We
have now migrated to cmake and are no longer maintaining qmake anyways
and therefore there is no reason to keep it.
Removing it also clearly states to any potential user/programmer that
this project is no longer intended to be compiled with qmake.
Given that the .pri files no longer exist, the mumble-version.py script
had to be adapted to read the version from the CMakeLists.txt file
instead.
Furthermore a few of the submodules support cmake natively and therefore
we no longer need the src/buid-directory approach in order to build
them. The respective build dirs have been removed and the src-dirs have
been renamed.
Now that test.pri adds source files and headers by default, the .pro files
of our tests need to append to SOURCES and HEADERS to ensure everything
test.pri adds to SOURCES and HEADERS are kept around.
The murmur_pch.h file which most tests use -- either directly,
or indrectly -- depends on being able to include OpenSSL headers.
Some of our tests did not include(qmake/openssl.pri), which meant that
those tests would fail to build in CONFIG(no-pch), such as on macOS.
This commit works around that issue by depending on OpenSSL for all tests.
The class implements an API similar to OpenBSD's arc4random:
- A way to get a random uint32_t. (arc4random)
- A way to get a random uint32_t with an upper bound. (arc4random_uniform)
- A way to fill a buffer with random data. (arc4random_buf)
