error: clean up comparison of word vectors

The function wordvcmp returned -1 when either of the word vectors was
short; this made the function asymmetric. Since the function is only
used to compare two word vectors for equality, restrict it to this
particular use case.

error: use separate tokens for characters, integers and pointers

Assisted by lint's queries 10, 14, 15.

No binary change.

error: enable lint's strict bool mode

This cleans up the inconsistencies between 'int', 'boolean' and 'bool'.

error: remove redundant parentheses around return value

No binary change.

fix various typos, mainly in comments.

PR 51298 David Binderman: simplify redundant conditionals

avoid "... dutch" being interpreted as a pascal continuation message, and
core-dumping.

Pass WARNS=4, not without some gross preprocessor hackery.
XXX: does this program actually do anything useful these days?

Assorted minor cleanup:
- use stdbool.h (partly)
- move extern declarations of data to header files
- use right types for calloc() wrapper
- remove bogus casts on return values
- remove excessive Pascal-style parentheses in conditionals
- a couple const fixes
- fix some typos in comments

Coverity CID 2333: Fix memory leak.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

get rid of strsave(), use strdup directly

Remove #ifndef'd __STDC__ code. ANSIfy.

fix redundant and nested decls

Eliminate hard coded buffer sizes in fgets() statements, use
strlcpy() to avoid buffer overflows, increase filename buffer
to MAXPATHLEN. (from OpenBSD)

char -> unsigned char

Get rid of multiply defined common symbols
langauge should be language in error.h

WARNSify (big job!), fix .Nm usage

Sync with 4.4lite2

Add RCS identifiers.

branches: 1.1.1;
added, from net/2 (patch 119).
