import:

- Fix typo in amd/nfs_prot_svc.c
- Manpage change in scripts/amd.conf.5
- Remove unneeded configure files
- Remove unneeded m4/macros

Bring man page back in shape. Many option descriptions lacked the
option name and paramaters they apply to and there was a mix of
formatting methods and styles.

I'm not sure that the description of "nfs_retransmit_counter" is
correct, but it does now at least match what's in -STABLE.

Resolve conflicts.

Uniformly refer to a file system as "file system".

mdoc(7) police:

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.

Prepare for mdoc(7)NG.

Fix miscellaneous mdoc macro argument limit infringements.

Merge our older Amd manpages with the new am-utils manpages.
The am-utils manpages were un-mandocafied, un4.4BSD'ed with CSRG
