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.

Andy Shevchenko (12):
lib/string_helpers: Switch to use BIT() macro
lib/string_helpers: Move ESCAPE_NP check inside 'else' branch in a
loop
lib/string_helpers: Introduce ESCAPE_NA for escaping non-ASCII
lib/string_helpers: Introduce ESCAPE_NAP to escape non-ASCII and
non-printable
lib/string_helpers: Drop indentation level in string_escape_mem()
lib/string_helpers: Allow to append additional characters to be
escaped
lib/test-string_helpers: Print flags in hexadecimal format
lib/test-string_helpers: Get rid of trailing comma in terminators
lib/test-string_helpers: Add test cases for new features
nfsd: Avoid non-flexible API in seq_quote_mem()
lib/string_helpers: Drop unused *_escape_mem_ascii()
MAINTAINERS: Add myself as designated reviewer for generic string
library
