arrays generically rather than duplicating a hack in all of the backends.
- Add two new system call argument types and use them instead of StringArray
for the argument and environment arguments execve and linux_execve.
- Honor the -a/-e flags in the handling of these new types.
- Instead of printing "<missing argument>" when the decoding is disabled,
print the raw pointer value.
Before truss would fetch 100 string pointers and happily walk off the end
of the array if it never found a NULL. This also means for a short argv
list it could fail entirely if the 100 string pointers spanned into an
unmapped page.
Instead, fetch page-aligned blocks of string pointers in a loop fetching
each string until a NULL is found.
While here, make use of the open memstream file descriptor instead of
allocating a temporary array. This allows us to fetch each string once
instead of twice.
- Print the ident value as decimal instead of hexadecimal for filter types
that use "small" values such as file descriptors and PIDs.
- Decode NOTE_* flags in the fflags field of kevents for several system
filter types.
with open_memstream() to build the string for each argument. This allows
for more complicated argument building without resorting to intermediate
malloc's, etc.
Related, the strsig*() functions no longer return allocated strings but
use a static global buffer instead.
The many christian denominations have different dates for their
celebrations and controversies are likely to be always.
These are well established and happen to be holidays in many
Catholic countries.

- Don't exit if get_struct() fails, instead print the raw pointer value to
match all other argument decoding cases.
- Use an xlat table instead of a home-rolled switch for the operation name.
- Display the nested socketcall args structure as a structure instead of as
two inline arguments.
sigqueue, sigreturn, sigsuspend, sigtimedwait, sigwait, sigwaitinfo, and
thr_kill.
- Print signal sets as a structure (with {}'s) and in particular use this to
differentiate empty sets from a NULL pointer.
- Decode arguments for some other system calls: issetugid, pipe2, sysarch
(operations are only decoded for amd64 and i386), and thr_self.
Its idea was to be a simple initiator and execute several commands from
kernel level, but FreeBSD never had consumer for that functionality,
while its implementation polluted many unrelated places..
As the name indicates, these are flags to pass to nm(1). The newer
binutils have a plugin mechanism so, to build something with LLVM's
LTO, we need to pass flags to nm(1). This commit also extends
lorder(1) to pass NMFLAGS to nm(1).
The option was added only to ease the transition from GNU Binutils to
ELF Tool Chain tools, and that process is now complete (for the viable
replacements). Noting the removal in UPDATING is sufficient as we have
not shipped a release with the option.
