lib: Add generic binary search function to the kernel.
There a large number hand-coded binary searches in the kernel (run
"git grep search | grep binary" to find many of them). Since in my
experience, hand-coding binary searches can be error-prone, it seems
worth cleaning this up by providing a generic binary search function.
This generic binary search implementation comes from Ksplice. It has
the same basic API as the C library bsearch() function. Ksplice uses
it in half a dozen places with 4 different comparison functions, and I
think our code is substantially cleaner because of this.
