1efe3c6b58 Add missing static keywords for global variables to tools in sbin/.
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.

5df69e92de recoverdisk(8): treat output file consistently and abort on EINVAL
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).

39d969aedf This is a small tool which will read an entire disk(partition) using
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
