string buffer for each linelist l_line into one large string. Since
linelists parsed out during the previous passes store the pointers to
previously allocated l_lines, the reallocation caused undefined
behaviour on accessing the buffers, and quite deterministic fault on
freeing them (in mountd(8) startup).
This fixes reading of netgroup(5) file which contains more then one
netgroup.

which was inadvertently caused by r236185: if SHLIBDIR is set using the
?= operator, it must be done *before* bsd.own.mk is included, otherwise
the default value is still used.
Note, bsd.lib.mk will take care of removing the copy in /usr/lib upon
installation, so no addition to ObsoleteFiles.inc is needed.

thing it was still used for was to set the "global default" password
hash. Since the stock auth.conf contained nothing but comments, the
global default was actually the first algorithm in crypt(3)'s list,
which happens to be DES; I take the fact that nobody noticed as proof
that it was not used outside of crypt(3).
The only other use in our tree was in the Kerberos support code in
in tinyware's passwd(1). I removed that code in an earlier commit;
it would not have compiled anyway, as it only supported Kerberos IV.
The auth_getval() function is now a stub that always returns NULL,
which has the same effect as a functional auth_getval() with an
empty auth.conf.

- Use CLOCK_MONOTONIC instead of CLOCK_REALTIME, because CLOCK_MONOTONIC
does not wrap into negative in near future. This fixes any potential
problems using "pthread_cond_timedwait()".
- Fix a bug where the "libusb_wait_for_event()" function computes an
absolute timeout instead of a relative timeout. USB transfers do
not depend on this timeout value.
- Add dependency towards LibPthread to Makefile, because LibUSB v1.0
needs this library to function correctly.

(Resolved state) recommend this way for the current standard (called
"earlier" in the text)
"However, earlier versions of this standard did not require this, and the
same example had to be written as:
// buf was obtained by malloc(buflen)
ret = write(fd, buf, buflen);
if (ret < 0) {
int save = errno;
free(buf);
errno = save;
return ret;
}
"
from feedback I have for previous commit it seems that many people prefer
to avoid mass code change needed for current standard compliance
and prefer to track unpublished standard instead, which requires now
that free() itself must save errno, not its usage code.
So, I back out "save errno across free()" part of previous commit,
and will fill PR for changing free() isntead.
2) Remove now unused serrno.

"The setting of errno after a successful call to a function is
unspecified unless the description of that function specifies that
errno shall not be modified."
However, free() in IEEE Std 1003.1-2008 does not mention its interaction
with errno, so MAY modify it after successful call
(it depends on particular free() implementation, OS-specific, etc.).
So, save errno across free() calls to make code portable and
POSIX-conformant.
2) Remove unused serrno assignment.

The stat structures returned on pipes seems to contain all the
information required by POSIX. Especially the wording "and thus to a
pipe" makes little sense, because it seems to imply a certain
relationship between sockets and pipes that simply isn't there.

Feature Change
* BIND now recognizes the TLSA resource record type, created to
support IETF DANE (DNS-based Authentication of Named Entities)
Bug Fix
* The locking strategy around the handling of iterative queries
has been tuned to reduce unnecessary contention in a multi-
threaded environment.
Other critical bug fixes are included.
All BIND users are encouraged to upgrade.
To avoid unexpected process termination from SIGPIPE when writing to a
closed network connection, enable SO_NOSIGPIPE on all network connections.
The POSIX standard MSG_NOSIGNAL is not used since it requires modifying all
send calls to add this flag. This is particularly nasty for SSL connections.
