Series lib/string_helpers: get rid of ugly *_escape_mem_ascii() | expand

Get rid of ugly *_escape_mem_ascii() API since it's not flexible and
has the only single user. Provide better approach based on usage of the
string_escape_mem() with appropriate flags.

Test cases has been expanded accordingly to cover new functionality.

This is assumed to go either thru VFS or Andrew's tree. I don't expect
too many changes in string_helpers.

Changelog v2:
- introduced seq_escape_mem() instead of poking seq_get_buf() (Al)
- to keep balance of seq_get_buf() usage, convert seq_escape() to use above
- added missed ESCAPE_APPEND flag in NFSv4 patch
- moved indentation patch closer to the beginning of the series
- reshuffled series to be in two groups: generic library extension
  followed by seq_file updates
