mbpk

I finished off the final part of mbpk_update_repositories!!!!!

It finally fetches the repository metadata, parses out the packages, and fetches them all independently!

I got it to save the repository metadata to a file and parse it!

Fixed a buffer overflow issue where I was writing 9 extra bytes outside of my allocated memory

Also got a basic strerr function working for libmbpk

I got libmbpk to use libcurl and fetch the repository INI file into a buffer!

I wrote out the full spec for my package manager written in C89, mbpk (Minimal Binary Package Kit), and got it to load the repository config INI file!
You heard that right, C89, because booleans are bloat.
C89 is based and you cannot deny
