There are several places in kernel where modules unescapes input to convert
C-Style Escape Sequences into byte codes.
The patch provides generic implementation of such approach. Test cases are
also included into the patch.

Moving these arrays into static storage shrinks the kernel a bit:

For files only using THIS_MODULE and/or EXPORT_SYMBOL, map
them onto including export.h -- or if the file isn't even
using those, then just delete the include. Fix up any implicit
include dependencies that were being masked by module.h along
the way.

We would hang forever when passing a zero to string_get_size().
Furthermore, string_get_size() would produce decimals on a value small
enough to be exact. Finally, a few formatting issues are inconsistent
with standard SI style guidelines.
- If the value is less than the divisor, skip the entire rounding
step. This prints out all small values including zero as integers,
without decimals.
- Add a space between the value and the symbol for the unit,
consistent with standard SI practice.
- Lower case k in kB since we are talking about powers of 10.
- Finally, change "int" to "unsigned int" in one place to shut up a
gcc warning when compiling the code out-of-kernel for testing.

This patch adds the ability to print sizes in either units of 10^3 (SI)
or 2^10 (Binary) units. It rounds up to three significant figures and
can be used for either memory or storage capacities.
Oh, and I'm fully aware that 64 bits is only 16EiB ... the Zetta and
Yotta units are added for future proofing against the day we have 128
bit computers ...
