Allocate a zeroed LDT.
Failing to do this might result in the LDT appearing to run out of free
descriptors because of random junk in the descriptor's 'sd_type' field.

MFC r261270:

Fix the ordering of the arguments to printf in
uhub_child_location_string(). This produced bogus information in

        dev.<USB driver>.<id>.%location

output from sysctl.
MFC r267436-267439:

- 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.

MFC	r267544:

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].

MFC r267600:

cxgbe(4):  Fix bug in the fast rx buffer recycle path.  In some cases rx
buffers were getting recycled when they should have been left alone.
MFC	r267426, r267464:

Avoid zeroing during allocation.

This change reverts a change from OpenBSD which made use of
calloc, and therefore wasted time initializing arrays that
will later be realloc'ed.

Consistently use FreeBSD's reallocf():
- Drop some bogus casts to size_t.
- The new_p_foo variables are not needed anymore.

Also merge the changes from OpenBSD's manpage
