strptime: add support for %t and %n
Posix strptime() requires support for %t and %n, which were added
to the illumos port. Curiously we were skipping white spaces by
default in most other cases making %t meaningless.
We now skip spaces in the case of the %e specifier as strftime(3)
explicitly adds a space for the single digit case.

Retooling addrconfig() to exclude addresses on loopback interfaces
when looking for configured addresses.
This change is based upon the code from the submitter, and made
following changes:
- Exclude addresses assigned on interfaces which are down, like NetBSD
does.
- Exclude addresses assigned on interfaces which are ifdisabled.
Use SOCK_CLOEXEC.

Update license to strptime(3) implementation.
Our strptime(3) implementation was the base for the illumos
implementation and after contacting the author, Kevin Rudy
stated the code is under a 2-Clause BSD License [1]
After reviewing our local changes to the file in question,
the FreeBSD Foundation has agreed that their contributions
to this file are not required to carry clause 3 or 4 so
the file can be relicensed as in Illumos [2].

- Replace malloc+memset with calloc.
- iconv_open(3): initialise ci_ilseq_invalid field of _citrus_iconv_shared
struct after allocation with malloc.
- iconvlist(3): reduce a memory leak by copying strings only once.
- iconv(1):
- Make invalids variable local to do_conv such that it prints the number
of invalid characters of the current file instead of an accumulated
value.
- Make do_conv return an error when invalid characters have been found.
Return EXIT_FAILURE from main if any file contained invalid characters.
This matches the behaviour of GNU iconv.
- Mark usage with __dead2 attribute.
- Make the long_options array const.

POSIX.1-2008 specifies that those two functions should be declared by

Add a new flag to /etc/ttys: onifconsole. This is equivalent to "on" if the
device is an active kernel console and "off" otherwise. This is designed to
allow serial-booting x86 systems to provide a login prompt on the serial line
by default without providing one on all systems by default. Set this flag
on x86 systems for ttyu0.

non-directories.
If realpath() is called on pathnames like "/dev/null/." or "/dev/null/..",
it should fail with [ENOTDIR]. Pathnames like "/dev/null/" already failed as
they should.
Also, put the check for non-directories after lstatting the previous
component instead of when the empty component (consecutive or trailing
slashes) is detected, saving an lstat() call and some lines of code.

Add the deprecated fp{get,set}* functions, a few ports use them.
Rename the fp{get,set}* files so they no longer conflict with the
softfloat version of these files.
Implement __flt_rounds for ARMv6 hard-float. The fpscr register stores the
current rounding mode used by the VFP unit.
Simplify how we build MACHINE_ARCH. There are 3 options that may be set
however only arm, armeb, armv6, and soon armv6hf will be used.
Add the llvm/clang patch for r263619.
Reorder the pmap macros so "ARM_MMU_V6 + ARM_MMU_V7" is first. As they are
identical this allows us to build for both v6 and v7 together.
Add code for enabling second CPU core for A20 SoC.
Enable SMP on Cubieboard2.
Switch to freebsd.org emal address in copyright.
Export _libc_arm_fpu_present as a private symbol to be used by other
system libraries, for example libm.
On armv6 access both the softfloat and, when available, the vfp to get and
set the floating-point environment.
Build fenv-vfp.c with the softfp float abi. Without this gcc generates an
incorrect assembly file that doesn't allow for vfp instructions.
Only build the vfp/softfp switching code on armv6 as we don't support vfp
on anything earlier than this. This should fix the armeb and arm builds
when using gcc.
Add an optimised version of the float and double helper functions.

Merge the projects/clang-sparc64 branch back to head. This brings in
several updates from the llvm and clang trunks to make the sparc64
backend fully functional.
Apart from one patch to sys/sparc64/include/pcpu.h which is still under
discussion, this makes it possible to let clang fully build world and
kernel for sparc64.
Any assistance with testing this on actual sparc64 hardware is greatly
appreciated, as there will unavoidably be bugs left.
Many thanks go to Roman Divacky for his upstream work on getting the
sparc64 backend into shape.

The posix_fallocate(2) syscall should return error number on error,

MFC r261290:
The posix_madvise(3) and posix_fadvise(2) should return error on

Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit. Instead use (1U << 31) which gets the
expected result.
Similar to the (1 << 31) case it is not defined to do (2 << 30).
This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.
A similar change was made in OpenBSD.
Fix several bugs in sctp_bindx():
* Set errno to EAFNOSUPPORT if an address is provided which is neither

* Handle the case correctly where the first address provided is

The compile time constant limit on number of swap devices was removed in 5.2.
As such, remove the EINVAL error saying so. Currently the vm.nswapdev sysctl

Do not force to run atexit handlers, which text comes from a dso owning
the handle passed to __cxa_finalize() but which are registered by other

r258537 (hrs):
Add ICONV_{GET,SET}_ILSEQ_INVALID iconvctl. GNU iconv returns
EILSEQ when there is an invalid character in the output codeset
while it is valid in the input. However, POSIX requires iconv()
to perform an implementation-defined conversion on the character.
So, Citrus iconv converts such a character to a special character
which means it is invalid in the output codeset.
This is not a problem in most cases but some software like libxml2
depends on GNU's behavior to determine if a character is output
as-is or another form such as a character entity (&#NNN;).
r258587 (peter):
Move the iconv wrapper source from libc_nonshared to libc/iconv so
that it is all in the one place again. Rename libc/iconv/iconv.c
to bsd_iconv.c. Compile the wrappers into libc.a so that
WITHOUT_DYNAMICROOT works again.
