Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

Enough compatibility work to make figlet build and run! I ran out of steam writing library routines and imported two BSD-licensed libc routines: sscanf() and getopt(). I will most likely rewrite them sooner or later. For now I just wanted to see figlet running.

LibC: run clang-format on getopt.h to remove tab characters

LibC: Borrow a slightly more functional getopt() We were already borrowing a getopt() from the BSD family until the day we write our own. This patch borrows a slightly more modern one so we also get getopt_long(). Fixes #190. See also #91 for the desire to eventually NIH our own getopt()..
