[PATCH v3 00/11] lib: introduce string_escape_mem and %*pE specifier

[Andy Shevchenko]

The introduced function is a kind of opposite to string_unescape. We have
several users of such functionality each of them created custom implementation.
The series contains clean up of test suite, adding new call, and switching few
users to use it via %*pE specifier.

Test suite covers all of existing and most of potential use cases.

Changelog v3:
- address Joe's comments (typos and styling of documentation / commit messages)
- add patch 7/11
- rebase on top of recent linux-next

Changelog v2:
- addressed Joe's comments:
 - added patch 4/10
 - moving patches 5/10-10/10 to %*pE instead of direct string_escape_mem call,
   as a result the series and code looks cleaner 
- address few of Andrew's comments:
 - added patch 1/10
 - kernel documentation moved to c-file
 - when test case fails the necessary messages are printed on KERN_WARNING
   level
