Repeating the default WARNS here makes it slightly more difficult to
experiment with default WARNS changes, e.g. if we did something absolutely
bananas and introduced a WARNS=7 and wanted to try lifting the default to
that.
Drop most of them; there is one in the blake2 kernel module, but I suspect
it should be dropped -- the default WARNS in the rest of the build doesn't
currently apply to kernel modules, and I haven't put too much thought into
whether it makes sense to make it so.
data-archæology project:
-u pattern
Fill unread parts of the output with pattern.
Default pattern is "_UNREAD_", empty pattern disables.
-v
Fancy status reporting using ANSI escapes and UTF-8
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.

recoverdisk(1) wants to know about read errors when doing the 1MB/64k
reads as fast as possible so it can continue and retry them later with
smaller reads (down to sector size). Any retries by lower layers will
only slow it down.

These tools declare global variables without using the static keyword,
even though their use is limited to a single C-file, or without placing
an extern declaration of them in the proper header file.
This improves usability a little as we no longer require using touch.
Also reword the manpage wrt. parameters and fix usage() [1]
With no media in a cd(4) drive, the reads will loop producing EINVAL,
abort in that case [2].
Document the shortcoming of sectorsize and MAXPHYS (a quick solution
to this might be having MAXPHYS as the "bigsize", in short testing it
didn't make a difference on throughput).

1M blocks and optionally write the read data to a file or disk.
If a read error happens, the 1M block gets put on the end of the worklist
and will be retried with 64k blocksize.
If a read error happens again, the 64k block gets put at the end of the
worklist and will be retried with single sector reads.
The program keeps trying until you stop it.
You can refresh a disk:
recoverdisk /dev/ad1 /dev/ad1
or salvage a floppy:
recoverdisk /dev/fd0 myfloppy.flp
