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 v3:
- dropped moving seq_escape() to the header due to a lot of complaints from
the (very) old code
- added seq_escape_str() inliner
- converted seq_escape() to use seq_escape_str() instead of seq_escape_mem()
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
