Spelling fixes for usr.bin/

Move the check to ensure the locate database has the minimum required size
when using mmap() before invoking mmap(). This avoids a confusing error
message when locate is invoked against a zero-size database after the
recent change to make mmap() fail requests to map 0 bytes.

A global is used even though the value is
passed through the function call.

getopt and friends are declared in <unistd.h>
getopt returns -1 not EOF.

$Id$ -> $FreeBSD$

Use err(3). Use .Pa macro for filenames in man page.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Sweep through the tree fixing mmap() usage:

- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.

Discussed with: bde

Make the long-awaited change from $Id$ to $FreeBSD$

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.

8-Bit character support.

Old locate(1) programs still works with the new database format, print
some garbage for 8 bit characters, but don't core (maybe except char 30).

7-Bit Puritan should not notice any difference. Same speed,
Same database size if the database contain only ASCII characters.
