aae634b518 Soft-float support for rounding mode is currently not thread-safe, which 
is not acceptable. Decision should be made on whether full fenv.h
support is desirable and then fix this appropiately.

Math functions (both libc and libm) should not touch errno, this creates
unnecessary problems for compilers.

f9589d4feb Release 2015g - 2015-10-01 00:39:51 -0700 
Changes affecting code

    localtime no longer mishandles America/Anchorage after 2037.
    (Thanks to Bradley White for reporting the bug.)

    The localtime module allows the variables 'timezone', 'daylight',
    and 'altzone' to be in common storage shared with other modules,
    and declares them in case the system <time.h> does not.
    (Problems reported by Kees Dekker.)

    On platforms with tm_zone, strftime.c now assumes it is not NULL.
    This simplifies the code and is consistent with zdump.c.
    (Problem reported by Christos Zoulas.)

  Changes affecting documentation

   The tzfile man page now documents that transition times denote the
   starts (not the ends) of the corresponding time periods.
   (Ambiguity reported by Bill Seymour.)

Make this work on !NetBSD platforms:

- include nbtool_config.h for cross builds to get definition of __RCSID()
- restore errno in the last rare code path for platforms affecting errno(2)
  in memcpy(2)

While there: rename parameter name 'num' to 'number' to be in sync with
the calloc(3) parameter naming.

c9baa5968d Introduce reallocarr(3) for easy (re)allocation of memory with overflow

leaks on allocation failures and it doesn't depend on malloc(0) != NULL
for correct error checking. Compared to plain realloc, it also avoids
the problem of intermediate integer overflows. The trade-off is the use
of void * to side step C type system with regard to generic pointer to
pointer.

To achieve the documented behavior and to fix long standing incorrect
rsh(1) behavior which I've tried to fix in rev. 1.36, rcmd(1) should have
two operation mode; whether it should relay signal information on
auxiliary channel or not, depending on the argument `fd2p' passed to rcmd(3).
So, make rcmd(1) behave differntly depending on the environment variable and
set it when necessary in rcmd(3) according to how auxiliary channel
is set up by rcmd(3).

- According to POSIX, fdopendir() transfers ownership of the fd only on

ff104b2e4b PR/48475: YAMAGUCHI Takanori: EDNS option broken with unbound. struct 
querybuf in net/gethnamaddr.c defines MAXPACKET to 64K. This in turn
gets passed down until it reached res_nopt(..., answer, anslen), where
the size of the buffer must fit in 16 bits. Unfortunately we end up
being one more than the max so we end up sending a 0 as the size and
unbound does not like that. Instead we clip now to 64K - 1, and everyone
is happy.

7cbb46f7c6 Add negative offset checks to fseeko 
These were not strictly needed before, as lseek would error on negative
arguments, but having added open_memstream we have a virtual file pointer
that assumes that it gets sane values, so we get an assertion triggered
on a negative value. Best to check in one place rather than at all the
relevant points.

5b3acd55fe - don't leak errno in mktime() 
- when we load a new timezone, don't change anything unless the load succeeded.

355ccc569e PR/49284: Andreas Gustafsson: sysinst segfaults when configuring network 
manually. When tzload() fails called from zoneinit(), when trying to set the
local timezone for the first time in tzsetlcl(), we end up with a lclptr
that contains garbage, so settzname() core-dumps.

Thanks Andreas for the analysis!
