Ensure the special cases trigger whether we come via a referral
or via the -c option. Match host names case-insensitively.
Use the default character set supported by .de (UTF-8) since that
is more compatible with the modern world than ISO 8859-1. Persuade
them to give us a useful answer whether an internationalized
domain name is given in UTF-8 or in punycode.
The IANA whois server has the right referral information for domain
names, IP addresses, and AS numbers, so whois does not need to be
able to choose servers itself (except for a few cases where referrals
do not work). We can delete a chunk of code, which is always fun.
This change improves the referral handling to be less sensitive to
all the various formats, and to allow multi-hop referral chains,
such as IANA -> registry -> registrar.
ARIN queries have the "+" flag added if no flags are present, so we
get full details if the query matches multiple objects. The Verisign
anti-spam logic is also now suppressed if the user provided a non-
trivial query string.
Uninformative rubric is now trimmed by default. The -S option
turns off trimming, and disables query fettling.
The -i option is back to its traditional pre-1999 hostname, since
whois.internic.net is more useful than whois.networksolutions.com.
Note that the old fallback/default server whois.crsnic.net is an
alias for whois.internic.net.
The manual is more informative about query syntax.
Look up AS numbers at ARIN.
Handle more referral formats.
Suppress spammy nameserver objects when querying the .com and .net
whois servers by explicitly querying for domain names by default.
The bad_truncate test sets the uimmutable flag to produce an error in
truncate, but that flag isn't supported by ZFS. If /tmp is on a ZFS
filesystem, the test will fail. Change it to use readonly permissions and
an unpriveleged user instead.

This will also allow these to be build with Thumb-2 when we get this

up to now.
The new sendfile is the code that Netflix uses to send their multiple tens
of gigabits of data per second. The new implementation features asynchronous
I/O, when I/O operations are launched, but not awaited to be complete. An
explanation of why such behavior is beneficial compared to old one is
going to be too long for a commit message, so we will skip it here.
Additional features of new syscall are extra flags, which provide an
application more control over data sent. The SF_NOCACHE flag tells
kernel that data shouldn't be cached after it was sent. The SF_READAHEAD()
macro allows to specify readahead size in pages.
The new syscalls is a drop in replacement. No modifications are required
to applications. One can take nginx binary for stable/10 and run it
successfully on head. Although SF_NODISKIO lost its original sense, as now
sendfile doesn't block, and now means something completely different (tm),
using the new sendfile the old way is absolutely safe.

Similar fix was done for passwd and group operations in r285050. When a
temporary file is created and then renamed to replace official file there
are no checks to make sure data was written to disk and if a power cycle
happens at this time, system can end up with a 0 length file

- Added an expression parser so that expressions from headers are now working
- Fixed missing null terminators on cross references
- Disabled exceptions / RTTI in the build for smaller binaries
- Changed phandle order generation to be identical to GPL'd dtc
This is rather pedantic, as for most architectures it holds that
sizeof(type *) == sizeof(type **)

sysdecode_ioctlname() function. This function matches the behavior
of the truss variant in that it returns a pointer to a string description
for known ioctls. The caller is responsible for displaying unknown
ioctl requests. For kdump this meant moving the logic to handle unknown
ioctl requests out of the generated function and into an ioctlname()
function in kdump.c instead.

system call information such as system call arguments. Initially this
will consist of pulling duplicated code out of truss and kdump though it
may prove useful for other utilities in the future.
This commit moves the shared utrace(2) record parser out of kdump into
the library and updates kdump and truss to use it. One difference from
the previous version is that the library version treats unknown events
that start with the "RTLD" signature as unknown events. This simplifies
the interface and allows the consumer to decide how to handle all
non-recognized events. Instead, this function only generates a string
description for known malloc() and RTLD records.
