cutils

Common functions used in the xmidt-org programs.

Now that meson makes including subprojects easy, let's move common functions into a shared library.

What goes in here?

Generally annoying things you'd expect to just work. Reliable strnlen(), strdup(), strndup() are a few. maprintf() that just outputs to a correctly sized buffer you free (& the common friends).

There are some useful non-localized versions of string functions. These are important for libraries that deal with networking focused protocols.

There is a safer version of realloc() as well as memdup() ... because it happens & you need to do it.

And a few other favorites: xxd() which is a debugger's dream for outputting buffers.

Plus yet another base64 implementation for both standard as well as url versions.

What doesn't go in here?

If it doesn't feel like it's "missing" from a "standard library" then it goes elsewhere.
