lib: Merge libmisc into libshadow

The separation was unnecessary, and caused build problems. Let's go wild and obliterate the library. The files are moved to libshadow. Scripted change: $ find libmisc/ -type f \ | grep '\.[chy]$' \ | xargs mv -t lib; Plus updating the Makefile and other references. While at it, I've sorted the sources lists.
