Fix misleading indentation warning:

usr.sbin/lmcconfig/lmcconfig.c:941:39: error: misleading indentation; statement is not part of the previous 'if' [-Werror,-Wmisleading-indentation]
return 64.0;
^
usr.sbin/lmcconfig/lmcconfig.c:940:3: note: previous statement is here
if ((vga >= 0x3A) && (vga < 0x3F)) return 50.0 + 2.80 * (vga - 0x3A);
^

Direct commit to stable/11, since lmcconfig has been removed from
FreeBSD 12 and later.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Use strlcpy() instead of strncpy() when copying ifname to ensure
that it is NUL terminated. Additional NUL padding is not required
for short names.

Cleanup unnecessary semicolons from utilities we all love.

Use NULL instead of 0 for pointers.

fopen(3) will return NULL in case it can't open the STREAM.

Add META_MODE support.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

Rework time handling.

After I made the previous commit, I noticed the code does some things it
shouldn't. It casts a struct timeval to a time_t, assuming tv_sec is the
first member. Also, we are not interested in microseconds, so it is
better to just call time(NULL).

Remove unneeded struct timezone.

We're only interested in a timestamp -- not the timezone.

mdoc: fix column names, indentation, column separation within each row, and
quotation. Also make sure we have the same amount of columns in each row as
the number of columns we specify in the head arguments.

Fix type used to hold fgetc(3) output, this should help arm and powerpc
which have char == unsigned char

Remove useless conditional.

`vga' cannot be less than 0x3f when reaching the check.

The last big commit: let usr.sbin/ use WARNS=6 by default.

Include string.h for strncpy prototype
Include strings.h for bcopy and bzero prototype

Style.

[mdoc] add missing space before a punctuation type argument.

- Stop talking about non-FreeBSD stuff (mostly because it's hard
to keep this info up-to-date as time goes by).
- Revise the markup.

Add the lmcconfig tool for controlling the lmc driver. Add man pages and
glue.
