package/libb64: new package

This patch adds libb64, a library of ANSI C routines for fast
encoding/decoding data into and from a base64-encoded format.

The package contains a static library, headers, and an executable.
The latter, however, requires C++ and offers no advantages over busybox
or coreutils base64, so it is not installed. Therefore, nothing is
installed to target.

[Arnout:
- properly wrap Config.in
- move from Crypto to Other menu
- don't install to target
- don't make headers executable
- don't add -D to install with multiple source files
- extend commit log]

+	help
+	  libb64 is a library of ANSI C routines for fast encoding
+	  and decoding of data into and from a base64-encoded format.
+	  C++ wrappers are included, as well as the source code for
+	  standalone encoding and decoding executables.
+
+	  Base64 uses a subset of displayable ASCII characters, and is
+	  therefore a useful encoding for storing binary data in a text
+	  file, such as XML, or sending binary data over text-only
+	  email.
