Originally reported on Google Code with ID 346

We seem to be missing interceptors for a few frequent libc string  functions. They are
not easy to handle even in asan-ified glibc, so we need interceptors anyway. 

Anyone?

We can take this if you don't mind waiting couple of weeks.

You are more than welcome. 
Please add the interceptors to sanitizer_common, 
add run-time guards (two different flags, I think: replace_strstr and replace_strcspn),
and add tests similar to test/sanitizer_common/TestCases/pthread_mutexattr_get.cc

When you actually start working on it, claim this bug so that others don't work on
it in parallel.
