FIX for "nih {search,metainfo} -{o,I}".
It does not fail anymore if .nih/pkg_summary.txt is absent.
Option -I for "list", "deps', "meta", "info" and "search" was renamed to -i.
-I pt for backward compatibility.
TODO: -1 task (done)
nih refresh: option -P was added for fully rescanning pkgsrc tree.
"nih info" now defaults to -3 mode
"nih meta" now defaults to -1 mode (internally)
nih {info,meta}: documentation for -1|-3|-9 ads added
nih {search,info}: new option -l and config function "summary2filelist"
FIX: default PKGSRCDIR is not determined at build time anymore.
As a result "nih search -p" does not fail when accessing /tree/pkgsrc
used by bouyer@. Now PKGSRCDIR defaults to /usr/pkgsrc.
