This function is the reverse of human_to_size, and converts integer byte
sizes to human readable SI prefixed values.
A logical extension of this might be to mimic the formatter that pacman
uses and allow a second argument to be passed in which can coerce the
size, rather than reducing until the unit count is below 1024.

This is a bash wrapper around an awk function that parses human readable
sizes and returns their representative values in bytes, as a string. A
small test harness is added to validate the functionality.

This will replace our current options parser used in pacman-key,
makepkg, and ideally elsewhere. It follows heuristics closer to that of
GNU getopt long (and thus pacman itself), with the exception that it
does not allow for options with optional arguments. Due to the way this
parser will be used, this sort of functionality will not be needed.
Instead of relying on eval+set, options are normalized into an array,
OPTRET, which callers should expect to be populated after returning from
parseopts. This avoids problems with quotes and spaces in arguments,
assuming that the user quotes properly when passing into the
application.
A new test harness for parseopts is added in test/scripts.

Add a README file to briefly document the code snippets in the scripts
library folder.
