build: replace autotools with meson & ninja

Browse Source 
Port the project from autotools to meson. All build options are
preserved with the same semantics.

The goal of this change is to produce the same set of files as the
current autotools approach: libraries with correct SONAME/version,
headers, pkg-config files, GObject introspection data, Python extension
modules, D-Bus interface and configuration files. This is done to enable
a one-liner test command running all available test suites.

The only thing we drop is the `make docs` target as it's rarely used and
docs can be generated easily with sphinx directly. They are also not
required for testing.

The Rust workspace is built via a custom target that invokes cargo and
uses SYSTEM_DEPS_* environment variables to point the libgpiod-sys and
gpiosim-sys crates at the locally built C libraries.

In addition to porting the build files to meson, update the docs, remove
unneded items from .gitignore files (or remove them entirely if they're
no longer needed) and update the shunit2 test scripts to no longer care
about source directories.
