moar string interceptors: strstr, strcasestr, strcspn, strpbrk #346

Open GoogleCodeExporter opened 9 years ago

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.
