This is basically a ``C compilation'' of the former whereis.pl file,
employing the same algorithms, and aiming at being mostly
UI-compatible to the old (legally tainted) 4.3BSD whereis(1). In
comparision, the 4.4BSD-Lite version is just another variant of
which(1) only, where in particular the option to search for source
directories is sorely missing.
While i was at it, i added two more options which i contemplated doing
long since. -x will suppress the run of locate(1) to find sources
that could not be found otherwise, potentially saving a lot of time
(but obviously, risking to not find some sources that are well hidden
in the tree). -q will omit the leading name of the query, so in
particular, you can now do something like:
cd `whereis -qs ls`
I'd explicitly like to thank johan for his review which was quite a
bit more than an average review, including sending me a lot of diffs.

OpenBSD's implementation lacks -p, and we don't want to
support the option now, only to lose it if/when we later
switch to OpenBSD's implementation.
This functionality is provided by which(1).

intentional, this behaviour is far too obnoxious given the number of
filenames such as rpc.statd we have.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
the 4.3BSD command. Rewritten from scratch after the old man page,
taking account for the different situation with man pages and source
tree hierarchy (re: /usr/src/gnu) of the FreeBSD project.
