Earlier user could define more blocks than device, or backing file for
loopback file system, had available. That lead to a system crash with
following commands;
fallocate --length 64KiB test-file
mkfs.minix -3 -i 842160 test-file 104882174
mkdir test-file.d
mount test-file test-file.d
cp /etc/service test-file.d
Killed
sudo umount test-file.d
The minix driver should probably not hang the whole kernel, but the least
that mkfs.minix ought to do is not to let users to get that condition
quite as easily.

Checks about inodes vs block sizes does not add much robustness. Both
values are derived at compilation time from struct minix_inode size, and
they form full definition circle.
Bad block check for none-block devices should not be supressed, user
requested it so let him have it.
Check for st_rdev == 0x0300 || st_rdev == 0x0340 was unreachable.

mkfs.minix misbehaves when attempting to create a large v2 or v3
filesystem. I finally traced it down to attempting to create too many
inodes so that the first zone is past 65535 blocks in. This obviously
doesn't work as the on-disk superblock says this is a 16 bit integer.
I wrote a patch that catches this, clamps to the absolute v2/v3 limit
(like it already does for v1), and sets the blocks per inode to a more
reasonable ratio when exceeding half a gigabyte. Having a half-gig
filesystem with most files being smaller than 3k isn't really reasonable.
I suppose if you don't want to adjust inode sizes automatically you could
take that part out, and it will just crab sooner.
Given the non-attention in the code, I suspect nobody ever had cause to
try such a big minix filesystem. Well I have my reasons involving some
deeply embedded work where ext2 would place too much strain on the
hardware.

The mnt_free_filesystems() relies on NULL as the last item in the
filesystems array. It's necessary to keep NULL there after failed
strdup() too, because we call mnt_free_filesystems() to deallocate
after error.

This patch adds support to logger for RFC6587 octet counting.
RFC6587 provides support for two sorts of framing:
1. Octet counting (at RFC6587 s3.4.1)
In essence each frame is preceded by a decimal length and a
space.
2. Non-transparent framing (at RFC6587 s3.4.2), also called
'octet stuffing'
In essence each frame is terminated by a `\n`
Prior to this patch, logger used option 2 (non-transparent framing)
on TCP, and used no framing on UDP. After this patch, the default
behaviour is unchanged, but if the '--octet-count' option is supplied,
option 1 is used for both TCP and UDP. Arguably octet count framing
makes little sense on UDP, but some servers provide it and this
allows testing of those servers.

This test is not too slow anymore and BTW since last script refactoring
it does work now even on slow/heavy-loaded systems.
