build: use allowed over enabled or not-disabled

Meson feature options are typically in a tri-state of enabled, disabled,
or auto.  The enabled and disabled functions on an option (from
`get_option`) no longer return true for auto features.  Instead, the
expectation is to use `allowed()` which is true for both enabled and
auto.

Switch all uses of `enabled` to `allowed`.
Switch all uses of `not disabled` to `allowed`.

gpioplus

gpioplus is a c++ wrapper around the linux gpio ioctl interface. It aims to provide c++ ergonomics to the usage.

Building

For a standard release build, you want something like:

meson setup -Dexamples=false -Dtests=disabled builddir
ninja -C builddir
ninja -C builddir install

For a test / debug build, a typical configuration is

meson setup -Dtests=enabled builddir
meson test -C builddir
