(and thus the default), always use strcasestr(). Discussed on tech@
with schwarze@. While here, fix the apropos.c usage() message to be
consistent with apropos(1) and clean up the EXAMPLES in apropos(1).

* Bugfix: Use all arguments, not just the last one.
* Use 'Nm~' instead of 'Nm,Nd~' to match OpenBSD behaviour.
* For the progname, accept '^whatis', not '^whatis$' to ease testing.

This is from a patch to tech@ as critiqued by schwarze@, checked in to
get the ball rolling.

but a few serious things as well:
* -M overrides MANPATH
* -m prepends to the path
* put back database close calls that got lost in mandocdb
* missing sys/types.h in manpath.c, needed for size_t

(although I still don't have -M, which is a big piece).
First, the default search path is the cwd. This will change to use -M
once I look over that code.
If MANPATH is specified, this replaces the cwd.
Both of these are augmented by -m.
If paths don't exist or don't have databases, they're silently ignored.
This makes perfect sense: you may be given a superset of possible paths.
The corner case of no paths (where, say, MANPATH consists of bogus paths
or the cwd is unreadable) simply means that no paths are searched.

directories containing mandocdb(8) databases. Some changes follow:
(1) don't support -M yet;
(2) fall back to cwd if no prior manpath has been specified;
(3) resolve manpages using realpath() to prevent consecutive chdir()'s
over relative paths;
(4) note where further error-reporting is required;
(5) fix leaking memory on exit in several cases.

apropos [search_type[,...]=]substring
apropos search_type[,...][,i]~regex
... and expression evaluation must take the search type into account.
This allows to:
* drop the global -I option and
* drop the enum match, just using a boolean int.

this when it completes; this is to keep it in-tree.
Right now this uses prefix notation. Ignore it. I'll make this into
infix notation real soon.
The goal of this (exprcomp and exprexec) is to have arbitrary logical
expressions.

inspired by apropos.c and mandoc-tools' mandoc-cgi.c). This uses UTF-8
right now for its re-writing, but will soon accomodate for the regular
suspects (this is a rather simple matter).
I also introduce man.cgi (cgi.c), which is a standalone CGI that replaces
mandoc-tools' mandoc.cgi. Right now it's just a framework.

results array. This is much faster than the previous method, a linear
search, at a small cost. Note that array offsets are used instead of
storing the res pointer because we may realloc the results vector.

(originally including extern.h, state.c, and sort.c). The apropos
utility interfaces with the databases of mandocdb to provide semantic
searching capabilities. It Works For Me, but will need lots of cleanup
in the coming months.
