[PATCH v2 00/10] some string cleanup, and a tweak of the "config" command

[Rasmus Villemoes]

This started by me wanting something like what patch 8 does. That
wasn't too hard, except we had no strcasestr(), and also our regex
engine (which I didn't really want to pull into the mix anyway)
doesn't have a flag that requests case-insensitive matching. So I
wanted to add strcasestr(), but then I stumbled on a bunch of stuff
that should be cleaned up in str-land.

v2: Include Simon's R-b in the first 8 patches, incorporating most of
the minor comments. Patches 9 and 10 are new in v2.

Rasmus Villemoes (10):
  sh: clean up asm/string.h
  string: correct prototype of strchrnul()
  string: correct documentation for strstr and strnstr
  string: remove unused strswab() function
  string: remove more pointless __HAVE_ARCH_STR*
  string: add strcasestr()
  test: string: add test of new strcasestr() function
  cmd: config: allow simple filtering of output
  doc: document 'config' command
  test: add test of 'config' command
