Removed the unsafe nxt_memcmp() wrapper for memcmp(3).
The casts are unnecessary, since memcmp(3)'s arguments are 'void *'.
It might have been necessary in the times of K&R, where 'void *' didn't
exist. Nowadays, it's unnecessary, and _very_ unsafe, since casts can
hide all classes of bugs by silencing most compiler warnings.
The changes from nxt_memcmp() to memcmp(3) were scripted:
$ find src/ -type f \
| grep '\.[ch]$' \
| xargs sed -i 's/nxt_memcmp/memcmp/'
