Fix a -Wcast-qual warning in libkern's strtol(), by using __DECONST. No

Similar to r277901, fix more -Wcast-qual warnings in libkern's strtoq(),
strtoul() and strtouq(), by using __DECONST. No functional change.

is set.

Place the literal pool after a RET otherwise clang 3.5 tries to put it too

literal value here where it's close enough to be loaded.

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.

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).

- 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.

The original API calls for pow2ns, however the new APIs from
Linux call for seconds.
We need to be able to convert to/from 2^Nns to seconds in both
userland and kernel to fix this and properly compare units.
- Provide missing function that can do hashing of arbitrary sized buffer.
- Refetch lookup3.c and do only minimal edits to it, so that diff between
our jenkins_hash.c and lookup3.c is minimal.
- Add declarations for jenkins_hash(), jenkins_hash32() to sys/hash.h.
- Document these functions in hash(9)

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.
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.
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.
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.

When copying big structures, LLVM generates calls to memmove(), because
it may not be able to figure out whether structures overlap. This caused
linker errors to occur. memmove() is now implemented using bcopy().
Ideally it would be the other way around, but that can be solved in the
future. On ARM we don't do add anything, because it already has
memmove().

longer do we require SCTP to be in the kernel for the
lib to be able to handle SCTP. We do this by moving
the CRC32c checksum into libkern/crc32.c and then adjusting
all routines to use the common methods. Note that this
will improve the performance of iSCSI since they were
using the old single 256 bit table lookup versus the
slicing 8 algorithm (which gives a 4x speed up in
CRC32c calculation :-D)
