Resolve conflicts after import of Heimdal 0.6.1 libcom_err.

Add #include <stdlib.h> so that "s->strings = realloc(...)" doesn't segfault
on ia64. (This file isn't vendor branched)

SEE ALSO is the special name, and should not be taken in quotes,
since -mdoc checks for the "SEE" word only to set its variables.
In the SEE ALSO section, -mdoc automatically emits an empty line
before each new reference.

Prepare for mdoc(7)NG.

Fixed bitrot in K&R support (3 missing __P(())'s defeated the point of 7
non-missing ones in <com_err.h> which includes this file).

Fixed bitrot in K&R support (1 missing __P(()) defeated the point of 7
non-missing ones).

Removed private declaration of __P(()) while I'm here. Include
<sys/cdefs.h> to get the system definition. The privation declaration
would break the system definition if it were different.

Fix up this for the build; some compatibility files have been added -
these will be submitted back to KTH for inclusion.
