Fix LDADD/DPADD that should be LIBADD.

NO_MAN= has been deprecated in favor of MAN= for some time, go ahead
and finish the job. ncurses is now the only Makefile in the tree that
uses it since it wasn't a simple mechanical change, and will be
addressed in a future commit.

Start each of the license/copyright comments with /*-, minor shuffle of lines

Start the dreaded NOFOO -> NO_FOO conversion.

OK'ed by: core

For variables that are only checked with defined(), don't provide
any fake value.

Submitted by: bde (libbdf/Makefile)

style.Makefile(5):
Use WARNS?= instead of WARNS=.

While I'm here,
use INTERNALPROG, instead if overriding install
remove emty lines

Added missing DPADD.

This is a driver for IDT77252 based ATM interfaces. It has been tested
with a ProATM-155 and an IDT evaluation board and should also work
with a ProATM-25 (it seems to work at least, I cannot really measure
what the card emits). The driver has been tested on i386 and sparc64,
but should work an other archs also. It supports UBR, CBR, ABR and VBR;
AAL0, AAL5 and AALraw. As an additional feature VCI/VPI 0/0 can be
opened for receiving in AALraw mode and receives all cells not claimed
by other open VCs (even cells with invalid GFC, VPI and VCI fields and
OAM cells).

Thanks to Christian Bucari from ProSum for lending two cards and answering
my questions.
