Add missing DPADD to Makefile.

PR:	192733
Bring in the new automounter, similar to what's provided in most other
UNIX systems, eg. MacOS X and Solaris.  It uses Sun-compatible map format,
has proper kernel support, and LDAP integration.

There are still a few outstanding problems; they will be fixed shortly.

staticize two functions, and use proper format for a struct sglist

Add a few missing entries and fix entries that are obviously wrong.
The use of the old ISO language code "iw" for Hebrew was inconsistent
and it is replaced by the new language code "he" (which was already
used for the keyboard menu entry, but not for the menu heading or the
default font).

These changes are in preparation of the conversion of this file and
the keymap definitions to Unicode for use with NEWCONS.
sh: Don't hardcode relative paths in the tests stderr files.

These paths have had to be adjusted to changes in the testsuite runner
several times, so modify the tests to remove the need for such adjustment.

A cp in functional_test.sh is now unneeded, but this matters little in
performance.
sh: Reject integer overflow in number and is_number.

sh: Avoid overflow in atoi() when parsing HISTSIZE.

Side effect: a non-numeric HISTSIZE now results in the default size (100)

Attempt at converting the SYSCONS keymaps to Unicode for use with NEWCONS.
I have spent many hours comparing source and destination formats, and hope
to have caught the most severe conversion errors.

Files were converted with a Perl script which I'll shortly commit to the
tools directory. This script is a much enhanced version of the one
provided by ray@ and is expected to support the full kbdmap(5) syntax.

The naming convention used is:

 <2-letter country code>.<variant>.kbd

Only if there are multiple layouts for different languages:

 <2-letter country code>-<2-letter language code>.<variant>.kbd

In nearly all cases, the keyboards are country specific, only. Currently
there is only one case where the language was added ("ch-fr.kbd" for
the Swiss-French keyboard layout).

I choose to write Unicode character codes as hex numbers. While this
increases the diff to the SYSCONS keymap files for the trivial cases
(conversion from ISO8859-1), it really helps to verify the more complex
cases against a Unicode table (which is indexed by hex numbers).

This commit does not cover all files that have been converted, since I
need to sort out which ones to use, if there were several with different
source encodings to choose from.

Review and test of the keymap files is highly desirable before 10.1 is
released. I'd also appreciate educated opinions regarding the optimum
variant (to be made available as the default for each language).

Since there are no NEWCONS keymaps in 10-STABLE, I plan to MFC after
the minimum allowed delay of 3 days, to allow at least a few weeks to
test and improve what will be in the next release.

Expand the elf brandelf infrastructure to give access to the whole ELF
header (Elf_Ehdr) to determine if a particular interpretor wants to
accept it or not. Use this mechanism to filter EABI arm on OABI arm
kernels, and vice versa. This method could also be used to implement
OABI on EABI arm kernels, if desired, or to allow a single mips kernel
to run o32, n32 and n64 binaries.
