This isn't really the case, but GCC's analyzer currently thinks so, so
clean it up with a switch statement.

libpldm: Fix header use

The headers need to work whether we're building libpldm in the repo or
we're building another project depending on the headers in the system
include directory.

Tidy up the paths involved and switch to defining the public headers as
system headers for the purpose of the build.

libpldm: Explicit deprecated, stable and testing ABI classes

Experimenting with new APIs is important, but ABI stability of the
library is also important. We wish to have the freedom to add APIs
without being burdened by them being immediately set in stone.

We implement this wish by introducing three classes of ABI:

1. deprecated
2. stable
3. testing

These are enforced by corresponding function attributes:

1. LIBPLDM_ABI_DEPRECATED
2. LIBPLDM_ABI_STABLE
3. LIBPLDM_ABI_TESTING

Symbol visibility in the library is flipped to 'hidden' by default, so
one of these annotations must be used for the symbol to be exposed.

With these classes in place there are now clear points in time at which
we update the ABI dumps captured under the abi/ directory: When an API
is migrated from the 'testing' class to the 'stable' class, or when
removed from the 'deprecated' class.

Which classes of functions are exposed by the build is controlled by the
new 'abi' meson option. The option is of array type which contains the
list of ABI classes the build should consider. It defaults to enabling
all classes to provide test coverage in CI. The classes used should be
constrained to deprecated and stable (and not test) in any dependent
projects.

Further, shift the fixup for C's `_Static_assert` into src/msgbuf.h to
prevent a clang-tidy-16 error:

```

```

And fix up the function prototype in the definition of `pldm_open()`:

```
../src/requester/pldm.c:128:16: error: a function declaration without a prototype is deprecated in all versions of C [clang-diagnostic-strict-prototypes,-warnings-as-errors]

utils: Reimplement ver2str() for sanity

The dense mix of print_version_field(), snprintf() with its tricky
return semantics, and the tricky POINTER_MOVE() macro are replaced by an
implementation where each statement directly inserts one character into
the buffer while preventing buffer overflow.

While we're reworking ver2str(), change the return type to avoid
clang-tidy's bugprone-narrowing-conversion diagnostic. This is an
API/ABI break, but it's one with low impact: The test suite declares the
variable holding the return type as `auto`, while the one ver2str() call
in the entire openbmc github org, in pldmd, immediately discards the
return value (it is never assigned).
