Big cleanup of tools/ath_info.c

Big cleanup of tools/ath_info.c

Reformat with madwifi-indent, it was needed badly.  Break some long
lines.  Avoid complex structure initializers that GNU indent cannot
format.  Avoid using macro for the names table.  Remove spaces in the
names, add then with formatted output.  Remove spaces before punctuation
signs.

Fix all sparse warnings.  Default to base 16 for all numbers specified
on the command line.
