80199cdcb4 In preparation for adding inode check-hashes, clean up and
document the libufs interface for fetching and storing inodes.
The undocumented getino / putino interface has been replaced
with a new getinode / putinode interface.

Convert the utilities that had been using the undocumented
interface to use the new documented interface.

No functional change (as for now the libufs library does not
do inode check-hashes).

1c1781ccce Ensure that libnv can be used when kern.trap_enotcap=1.
libnv used fcntl(fd, F_GETFL) to test whether fd is a valid file
descriptor.  Aside from being racy, this check requires CAP_FCNTL
rights on fd.  Instead, use fcntl(fd, F_GETFD), which does not require
any capability rights.

Also remove some redundant fd_is_valid() checks to avoid extra system
calls; in many cases we were performing this check immediately before
dup()ing the descriptor.

f5c8eafe11 libcasper: introduce cap_fileargs service
cap_fileargs is a Casper service which helps to sandbox applications that need
access to the filesystem namespace. The main purpose of the service is to make
easy to capsicumize applications that works on multiple files passed in argv.

We have a couple example of using it but we still treat this service as an
experimental one.

improve performance of binaries that perform a lot of name

of Linux and Solaris.

The old code is left in place, should anyone need it, guarded
by #ifdef NS_REREAD_CONF.

17c10964b4 Reset persistent mbstates when rune locale encoding changes.
This was shown to be a problem by side effect of now-enabled test case,
which was going through C, en_US.UTF-8, ja_JP.SJIS, and ja_JP.eucJP,
and failing eventually as data in mbrtowc's mbstate, that was
perfectly correct for en_US.UTF-8 was treated as incorrect for
ja_JP.SJIS, failing the entire test case.

This makes the persistent mbstates to be per ctype-component,
and not per-locale so we could easily reset the mbstates when
only LC_CTYPE is changed.

9d1f434ebc libcasper: fix limitations in dns service
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,
and the ADDR names allow to use gethostbyaddr(3) and getnameinfo(3) functions.

a559f5f5a0 kern_poll: Restore explanatory comment removed in r177374
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
manual.

No functional change.
