The getaddrinfo(3) and gethostbyname(3) are used to return the address for a
given hostname. The getnameinfo(3) and gethostbyaddr(3) are used to return
hostname for a given address. Right now in casper, we have two limitations:
- NAME which allows resolving DNS names.
- ADDR which allows to do revert DNS lookups.
Before this change the rights was mixed up:
NAME - getnameinfo(3) and gethostbyname(3)
ADDR - gethostbyaddr(3) and getaddrinfo(3)
Which no matters on limitation allowed us to resolve DNS names and do DNS
lookups basically by using a different set of functions.
Now the NAME type allows getaddrinfo(3) and gethostbyname (3)functions,

The comment isn't stale. The check is bogus in the sense that poll(2)
does not require pollfd entries to be unique in fd space, so there is no
reason there cannot be more pollfd entries than open or even allowed
fds. The check is mostly a seatbelt against accidental misuse or
abuse. FD_SETSIZE, while usually unrelated to poll, is used as an
arbitrary floor for systems with very low kern.maxfilesperproc.
Additionally, document this possible EINVAL condition in the poll.2

no arguments. However, GCC accepts resolvers accepting arguments, and
our rtld passes CPU ID information (cpuid, hwcap, etc.) to ifunc

Both are significantly slower than hand-coded loops. See r338963 for
kernel commit.
bcmp differs from memcmp by always returning 1 when a difference is
found, as opposed to going for a value bigger or lower than 0
depending on what it is. This means it can do less work. For now the
code is duplicated and modified. This will get deduplicated after
another round of optimization when memcmp will get a longer-term form.
Both tested with the glibc suite. While the suite does not have a test
for bcmp, I created a wrapper routine which verified that values match
(0 vs 0, 1 vs non-zero).
