[sp: Credit for some of this implementation goes to Pieter, I
started off a patch he proposed for libgit2 but reworked
enough of it that I don't want to blame him for any bugs.]

These are easily built off the standard C library functions memcpy
and memcmp. By marking these inline we stand a good chance of
the C compiler replacing the entire thing with tight machine code,
because many compilers will actually inline a memcmp or memcpy when
the 3rd argument (the size) is a constant value.

We only want hex digits to be read, any other character in the 8-bit
character set is invalid within an id string.

By passing the name of the test function on the command line
we execute exactly that one test, and then exit successfully
if the test did not fail. This permits multiple functions in
the same .c file, so they could be called from a shell script
or debugged independently externally.

If we have more than one test build running we cannot use the same
file for each test case; instead we need to use a per-test path so
there aren't any collisions.

We should never have a noreturn style function in the library
itself, as such a function would prevent the calling application
from handling error conditions the way it wants.

This is a horribly simple test suite that makes it fairly easy to
put together some basic function level unit tests on the library.
Its patterned somewhat after the test suite in git.git, but also
after the "Check" test library.
