meson: Use declare_dependency for libraries

Now example binaries and tests don't have to be aware of the nuances for
configuring the build to use the library. This makes the project library
look like any other system dependency.

The previous commit adding meson support forgot to add the gpioplus
library to the pkgconfig file, so anything depending on gpioplus
wouldn't get the linker flag that is required to link against it.

autotools: Fix for autoconf-archive 2019.01.19

The code coverage macros from the archive changed in a backward
incompatible way. This adds a workaround to autodetect either version
and do the right thing.

Tested:
Builds with the old version of autotools using the CI. Manually
edited the CI to include the new 2019.01.19 version and ran the same
test to ensure the coverage results are the same.

test/handle: Don't need a virtual destructor

We aren't ever going to extend the mock implementation and even if we
did, only the base class needs to declare this.

Add a handle mock for use by other daemon's unit-tests. This saves a

utility/aspeed: Add gpio name to offset method

Useful for converting from the GPIO name listed in the chip or board
schematics to the offset which would be presented by the kernel. Made
constexpr so that the conversions can be done at compile time.

Ex:
gpioplus::utility::aspeed::nameToOffset("B3") -> 11

Tested:
Built and run through the unit test suite.
