instead of passing some of that state as arguments to print_syscall() and
print_syscallret(). This just makes the calls of these functions shorter
and easier to read.
For scripts using dialog(1) several times, it can be visually distracting
running dpv(1) several times amidst other dialogs. The `-k' option, similar
to dialog(1) `--keep-tite', enables the same functionality to smooth ti/te.
A new sysdecode_syscallname() function accepts a system call code and
returns a string of the corresponding name (or NULL if the code is
unknown). To support different process ABIs, the new function accepts a
value from a new sysdecode_abi enum as its first argument to select the
ABI in use. Current ABIs supported include FREEBSD (native binaries),
FREEBSD32, LINUX, LINUX32, and CLOUDABI64. Note that not all ABIs are
supported by all platforms. In general, a given ABI is only supported
if a platform can execute binaries for that ABI.
To simplify the implementation, libsysdecode's build reuses the
existing pre-generated files from the kernel source tree rather than
duplicating new copies of said files during the build.
kdump(1) and truss(1) now use these functions to map system call
identifiers to names. For kdump(1), a new 'syscallname()' function
consolidates duplicated code from ktrsyscall() and ktrsyscallret().
The Linux ABI no longer requires custom handling for ktrsyscall() and
linux_ktrsyscall() has been removed as a result.

STT_SPARC_REGISTER is a SPARC-specific symbol type specified by the
Sparcv9 ABI to provide some information on register use by the object.
Also rework st_info type lookup to avoid out-of-bounds array access.

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.

earlier point in the code to somewhere later.
This will also allow these to be build with Thumb-2 when we get this

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 **)
