The casts are unnecessary, since memchr(3)'s argument is 'const 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_memchr() to memchr(3) were scripted:
$ find src/ -type f \
| grep '\.[ch]$' \
| xargs sed -i 's/nxt_memchr/memchr/'

In src/nxt_http_route_addr.c::nxt_http_route_addr_pattern_parse() there
was potentially undefined behaviour when shifting a 32 bit value by 32
bits, this could happen if cidr_prefix was 0.
Promote the shiftee to unsigned long long to avoid this issue.
