Rework getaddrinfo(3) to return different error values for unresolvable
names (same as before, EAI_NONAME) and those without a requested addr
(EAI_ADDRFAMILY) when using DNS. This is implemented via an added
error in the nsswitch layer, NS_ADDRFAMILY, which is used only by
getaddrinfo(). The error is passed through nsdispatch(3), but that
routine has no changes to handle this error. The error originates in
the getaddrinfo DNS layer called via nsdispatch(), and is processed
by the search layer that calls nsdispatch().
While here, add a little style to returns near those that were
modified.

Fix an edge case by printing the required space when, the currency

the sign position precedes the quantity and the currency symbol.

Avoid an out-of-bounds access when trying to set the space_char using an
international currency format (%i) and the C/POSIX locale.
The current code tries to read the SPACE from int_curr_symbol[3]:
currency_symbol = strdup(lc->int_curr_symbol);
space_char = *(currency_symbol+3);
But on C/POSIX locales, int_curr_symbol is empty.
Three implementations have been examined: NetBSD[1], Darwin[2], and
Illumos[3]. Only NetBSD has fixed it[4].
Darwin and NetBSD also trim the mandatory final SPACE character after
reading it.
Locale Format Darwin/NetBSD FreeBSD/Illumos
en_US.UTF-8 [%i] [USD123.45] [USD 123.45]
fr_FR.UTF-8 [%i] [123,45 EUR] [123,45 EUR ]
This commit only fixes the out-of-bounds access.

Otherwise we do not fall back to sysctls if the auxv entries are not
defined by the kernel. Arguably this is not a bug since we do not
support newer libc running on an older kernel, but we can be a bit more
gentle for the benefit of Valgrind or any other software which
synthesizes the auxv for virtualization purposes.

file offsets. For example, in a 4K block size character device, geom
doesn't support writing / reading 515 byte blocks. The description is
perhaps not applicable to all EINVALs returned.
The read system call will return EINVAL if the current file offset is
not a multiple of the block size. This also applies to write(2). Add an
entry for EINVAL about this error to both man pages.

glibc-based interface.
Unfortunately, the glibc maintainers, despite knowing the existence
of the FreeBSD qsort_r(3) interface in 2004 and refused to add the
same interface to glibc based on grounds of the lack of standardization
and portability concerns, has decided it was a good idea to introduce
their own qsort_r(3) interface in 2007 as a GNU extension with a
slightly different and incompatible interface.
With the adoption of their interface as POSIX standard, let's switch
to the same prototype, there is no need to remain incompatible.
C++ and C applications written for the historical FreeBSD interface
get source level compatibility when building in C++ mode, or when
building with a C compiler with C11 generics support, provided that
the caller passes a fifth parameter of qsort_r() that exactly matches
the historical FreeBSD comparator function pointer type and does not
redefine the historical qsort_r(3) prototype in their source code.
Symbol versioning is used to keep old binaries working.

Long ago, ktr_tid was ktr_buffer which pointed to the buffer following
the header and was used internally in the kernel. Use was removed in
efbbbf570d and it was repurposed as ktr_kid in c6854c347f. For
ABI reasons, it stayed an intptr_t rather than becoming an lwpid_t at
the time. Since it doesn't hold a pointer any more (unless you have
a ktrace.out from 2005), change the type to long which is alwasy the
same size on all supported architectures. Add a suggestion to change
the type to lwpid_t (__int32_t) on a future ABI break.
Remove most remaining references to ktr_buffer, retaing a comment in
kdump.c explaining why negative values are treated as 0. While here,
accept that pid_t and lwpid_t are of type int and simplify casts in
printf.
This changed was motivated by CheriBSD where intptr_t is 16-bytes
in the pure-capability ABI.
