check the domain-name parameter according to the rules for "search"
strings as documented in resolv.conf(5). Specifically, the string must
be no more than 256 bytes long and contain no more than six valid domain
names separated by white space.
The previous unchecked values could result in a mangled resolv.conf
file which could effectively deny access to local sites. This is not
a security issue as rogue dhcp servers could already do this without
sending invalid strings.

device be created read+write, check to see if the backing store is read only
through the use of the access(2) system call. If this check fails returning
EACCES, EPERM or EROFS then gracefully downgrade the access to read only. Also
print a warning message to stderr, informing the user that the access mode
they requested is not available.

This changes only affects boot2; there are further loader changes

to take into account the new default of starting the first partition
after the boot blocks instead of at sector 0. If you used automatic
sizing when the first partition did not start at 0, you would get
an error that the automatically sized partition extended beyond the
end of the disk.
Note that there are probably still many more complex cases where
automatic sizing and placement will not work (e.g. non-contiguous
or out of order partitions).
ignore "no such file" errors only, which I wanted to do.
Because of this I ignored all other errors on dlopen(3) failure as well,
which isn't good.
Fix this situation by calling access(2) on library file first and ignore
only ENOENT error. This allows to report all the rest of dlopen(3) errors.

assertion it could call PKCS#5v2 with 4294967295 iterations).
Instead of failing on assertion, remind about '-p' flag.
