e0ac190e1e Provide explicit LC_C_LOCALE accessor and drop the various NULL checks. 
Provide LC_GLOBAL_LOCALE in a way that works with all locale functions.
Merge constant data used by the initial global locale and the C locale.
Drop function call layer for _current_locale() and directly return the
locale reference, not a pointer to it. Use protected access for global
variables, so that libc references can avoid the GOT overhead.

8588929dc5 Add "consttime_bcmp" and "explicit_bzero" functions for both kernel 
abd userland, as proposed on tech-security, with explicit_bzero using
a volatile function pointer as suggested by Alan Barrett.
Both do what the name says. For userland, both are prefixed by "__"
to keep them out of the user namespace.
Change some memset/memcmp uses to the new functions where it makes
sense -- these are just some examples, more to come.

d22a7f54f9 In wcscspn and wcspbrk, handle set size of 0 and 1 explicitly. 
For larger sets, use a bloom filter to avoid the inner loop for most of
the input. The current implementation uses a simple modular hash as
first function (well suited for input e.g. in ISO Latin character sets)
and a more complex multiplicative hash as second function with a filter
size of 512 Bit. This reduces the typical run time to O(n+m).

fa3abaaeb7 Bitwise operations on signed types are well-defined if the values 
happen to be positive, and indeed the values here were guaranteed
to be positive, but some compilers complained anyway, so convert
the bitwise operations to arithmetic operations.

0d34d14bb9 If SRCS contains any .S files then remove the corresponding .c file from 
SRCS and add to LSRCS (for lint).
Change the 'string' Makefiles so that the arch/*/string/Makefile.inc
need only specify the .S files for that architecture and not the .c
files for all the files they don't override.
