If input mail does not have a newline on the last line dma must add
one. This was broken by the addition of long-line splitting, with the
switch from strlen(line) to linelen returned by getline().

(cherry picked from commit 1694872231)
getline() returns -1 on erorr or EOF, so use that condition instead of
feof() and check that there was no error after the loop exits.

Per RFC2822 the maximum transmitted line length is "998 characters...
excluding the CRLF." In a file the maximum is 999 with the \n included.
Previously mail containing a line with exactly 999 characters would
bounce.

This was prompted by the recent pkexec vulnerability (CVE-2021-4034).
This change is being made on general principle for setuid/setgid
binaries and is not in response to an actual issue.

The restriction here is pretty late and pretty minimal. We need a lot
of authority to open password databases, and don't do much after that
point.

Most important change being:
dma - Fix security hole (#46)
Affecting DragonFly 4.6 and earlier, Matt Dillon fixed this in base after
finding out from BSDNow Episode 152. Comments following were from his commit
which explains better than I. Just taking his change and putting it here as well.
* dma makes an age-old mistake of not properly checking whether a file
owned by a user is a symlink or not, a bug which the original mail.local
also had.
* Add O_NOFOLLOW to disallow symlinks.
Thanks-to: BSDNow Episode 152, made me dive dma to check when they talked
about the mail.local bug.

It is a small and lightweight Mail Transport Agent.
It accepts mails from locally installed Mail User Agents (MUA) and delivers the
mails either locally or to a remote destination. Remote delivery includes
several features like TLS/SSL support, SMTP authentication and NULLCLIENT.
Make dma conditional to new WITHOUT_DMA option and make it respect WITHOUT_MAIL
