Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same

Spelling fixes.

Document the isnumber() and ishexnumber() functions, and explain how they
differ (at least in theory) from isdigit() and isxdigit().

Add a note to the Compatiblity section suggesting that these functions
only be used for byte values. Add cross-references to the wide-char
counterparts.

From the PR:

1. ctype.h defines digittoint(), isnumber() and ishexnmber(), yet

2. The ctype manpage references a non-existent manpage for
digittoint().

3. The isascii() manpage claims it is standards compliant, when
it isn't.

4. isblank() claims it is _not_ standards compliant, when it
is.

Fix by including the appropriate .Nm entries, and with a new digittoint.3
page.
