196b6346ba Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

6ccaf050cc Back out all POSIXified *env() changes.
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

f6aff4df9f Print (total - used) as the amount of available swap for a swap device
when printing swapinfo output, rather than (total), as that is (strictly
speaking) more accurate.

87827d7ae6 - Add a -h flag to pstat to print swap sizes in "human readable"
format, with humanize_number(3).

- Move the common parts of the code that prints the sizes for a single
  swap device and the total to a single function to avoid repeating
  the humanize_number() stuff all over the place.

- Change the type of CONVERT() from intmax_t to int64_t, since this
  makes calling humanize_number() easier but cast the values to
  intmax_t before printing them, to make use of the %jd format that
  printf() supports.

- Document the new -h flag in the manpage and bump its date.

0b0ae8e16e Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

Tested on: i386 sparc64

4a93c6295e - Modernize the format of the open file showing mode output:
. Print the column headers centered (except for the left-aligned
     TYPE header) using a different header for architectures where
     sizeof(uintptr_t) is not four.
   . Consistently do not print a '0x' prefix for hexadecimal values.
   . Separate columns by a single space character.
   . Pad the columns presenting an address or offset enough to hold
     their respective largest value.
   . Do not restrict the output to unknown file types, inodes and
     sockets; allow displaying of pipes, fifos, kqueues and crypto file
     descriptors too.
 - Shorten an overly long line by removing a cast of printf's return
   value to void.

ddf9ef103e Change struct file f_data to un_data, a union of the correct struct
pointer types, and remove a huge number of casts from code using it.

Change struct xfile xf_data to xun_data (ABI is still compatible).

If we need to add a #define for f_data and xf_data we can, but I don't
think it will be necessary.  There are no operational changes in this
commit.
