77a6678c42 dd: add 'fullblock' iflag
Adds a fullblock iflag for improved compatibility with GNU dd.
The new iflag can be used to ensure that dd calls retrieve the
expected amount of data when reading from pipes or unusual
filesystems.

It allows specifying amount of bytes directly (not only amount of
blocks) is also supported by GNU's Coreutils.

29ec116037 POSIX conformance documentation for busybox
Attached a start for POSIX conformance documentation for busybox (see
TODO file and discussion last week).
A table of all options as defined by POSIX and as implemented by
busybox (see for a FreeBSD example
http://people.freebsd.org/~schweikh/posix-utilities.html).

Only the tools that are stand-alone applets are documented (not ash
built-ins as 'read'), as there are multiple shells.
When there are two versions (echo) the stand-alone version was
checked. I think this may be the wrong way to go, as most users will
probably use the built-in version - but which shell?

The table was auto-generated by running, for each POSIX utility,
latest git allyesconfig* "busybox <tool> --help" and parsing the
output, and comparing that to tool options extracted from its man page
at http://www.opengroup.org/onlinepubs/9699919799/.
This means that it the usage string is not correct, the table is also
wrong. I noticed that for 'kill', for example, the usage string does
not mention the -s, -q, -o options.
For each option is set whether it exists in busybox and if it is, is
it compliant to the standard. Of course, checking compliance can only
be done manually - a process which will probably take some time (see
'cat' for example).

I didn't post the auto-generation script (python, ugly) because the
table will now change manually; I can post it if there is anyone
interested.

As for the tools not implemented by busybox at all, I think most of
them are indeed fairly esotetic. Some I was suprised to see missing
are link, file, newgrp, unlink.

* Well, almost allyesconfig - but nothing very POSIX-y was disabled.
