3914ddf8a7 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.

25166187e3 Fix unwind-info errors in our hand-written arm assembler code.
We have functions nested within functions, and places where we start a
function then never end it, we just jump to the middle of something else.
We tried to express this with nested ENTRY()/END() macros (which result
in .fnstart and .fnend directives), but it turns out there's no way to
express that nesting in ARM EHABI unwind info, and newer tools treat
multiple .fnstart directives without an intervening .fnend as an error.

These changes introduce two new macros, EENTRY() and EEND().  EENTRY()
creates a global label you can call/jump to just like ENTRY(), but it
doesn't emit a .fnstart.  EEND() is a no-op that just documents the
conceptual endpoint that matches up with the same-named EENTRY().

This is based on patches submitted by Stepan Dyatkovskiy, but I made some
changes and added the EEND() stuff, so blame any problems on me.

0cbce0671e Use strcasecmp() instead of strcmp() when checking user-supplied encoding
names so that encoding names are treated as case-insensitive.  This allows
the use of 'utf-8' instead of 'UTF-8' for example and matches the behavior
of iconv(1).

ca49624410 Fix ixp425 boot2 with ARM EABI:
- libkern is missing __aeabi_llsl, implement this by calling __ashldi3.
 - Because of how the asm entry macros are defined the boot2 code
   requires the unwind symbols to exist, include them in boot2.

dc15eac046 Use strchr() and strrchr().
It seems strchr() and strrchr() are used more often than index() and
rindex(). Therefore, simply migrate all kernel code to use it.

For the XFS code, remove an empty line to make the code identical to
the code in the Linux kernel.

41adcfa1d0 Remove the now unused skpc() function.
It was only used by ufs and ext2 and I have really strong doubts that
there are other pieces of code that also use this function. If it turns
out that external drivers use this code as well, I'd be happy to migrate
or revert.

Bump __FreeBSD_version while there.

de85bfc508 Introducing memcchr(3).
It seems two of the file system drivers we have in the tree, namely ufs
and ext3, use a function called `skpc()'. The meaning of this function
does not seem to be documented in FreeBSD, but it turns out one needs to
be a VAX programmer to understand what it does.

SPKC is an instruction on the VAX that does the opposite of memchr(). It
searches for the non-equal character. Add a new function called
memcchr() to the tree that has the following advantages over skpc():

- It has a name that makes more sense than skpc(). Just like strcspn()
  matches the complement of strspn(), memcchr() is the complement of
  memchr().

- It is faster than skpc(). Similar to our strlen() in libc, it compares
  entire words, instead of single bytes. It seems that for this routine
  this yields a sixfold performance increase on amd64.

- It has a man page.

eb4c31fd41 Add support for asterisk characters when filling in the GELI password
during boot.

Change the last argument of gets() to indicate a visibility flag and add
definitions for the numerical constants. Except for the value 2, gets()
will behave exactly the same, so existing consumers shouldn't break. We
only use it in two places, though.
