Libsodium utility functions

Functions

add_le	`add_le()` treats `x` and `y` as unsigned little-endian numbers and adds `y` to `x` modulo 2^(8*len) in constant time.
increment_le	`increment_le()` treats `x` as an unsigned little-endian number and increments it in constant time.
memcmp	`memcmp()` returns true if `x[0]`, `x[1]`, …, `x[len-1]` are the same as `y[0]`, `y[1]`, …, `y[len-1]`. Otherwise it returns `false`.
memzero	`memzero()` tries to effectively zero out the data in `x` even if optimizations are being applied to the code.
mlock	`mlock()` locks memory given region which can help avoiding swapping the sensitive memory region to disk.
munlock	`munlock()` unlocks memory region.
