ac89714515 Fix loader's ability to read the 10.1 release PowerPC ISOs. There appears to
be some kind of problem with the version of makefs used for these disks.
There may be a better way to handle this problem, so I've set the MFC
timer for a fairly long time period.

e44e2ac96c Add a divisor parameter to twiddle() so that callers can request that output
only happen on every Nth call.  Update the existing twiddle() calls done in
various IO loops to roughly reflect the relative IO sizes.  That is, tftp
and nfs call twiddle() on every 1K block, ufs on every filesystem block,
so the network calls now use a much larger divisor than disk IO calls.

Also add a new twiddle_divisor() function that allows an application to set
a global divisor that is applied on top of the per-call divisors.  Nothing
calls this yet, but loader(8) will be using it to further throttle the
cursor for slow serial consoles.

the oabi is still in the tree, but it is expected this will be removed

FreeBSD on ARMa 32-bit processors.

e8c9682c95 Add pkgfs, a file system implementation for reading files out of a
compressed tarball, aka package. The file system assumes that the
files are layed-out in the same order as needed to allow for the
package to be streamed. As such, it does not read an entire package
into memory first.

Some properties of the file system:
o   Files that start with '+' are silently skipped. These are found
    in FreeBSD package files.
o   Files smaller than or equal to 4KB will be cached in memory and
    as such allow for some flexibility in accessing files out of
    order.
o   Files with the .tgz suffix are assumed to be (sub-)packages and
    signal the end for a directory scan.

d8a11be2f4 Provide a means for loaders to control which file system to use. This
to counteract the default behaviour of always trying each and every
file system until one succeeds, or the open fails. The problem with the
loader is that we've implemented features based on this behavior. The
handling of compressed files is a good example of this. However, it is
in general highly undesirable to not have a one-time probe (or taste
in the geom lingo), followed by something similar to a mount whenever
we (first) read from a device. Everytime we go to the same device, we
can reasonably assume it (still) has the same file system. For file
systems that need to do far more that a trivial read of a super block,
not having something similar to a mount operation is disastrous from
a performance (and thus usability) perspective.

But, again, since we've implemented features based on this stateless
approach, things can get complicated quickly if and when we want to
change this. And yet, we sometimes do need stateful behaviour.

For this reason, this change simply introduces exclusive_file_system.
When set to the fsops of the file system to use, the open call will
only try this file system. Setting it to NULL restores the default
behaviour. It's a low-cost (low-brow?) approach to provide enough
control without re-implementing the guts of the loader.

A good example of when this is useful is when we're trying to load
files out of a container (say, a software packaga) that itself lives
on a file system or is fetched over the network. While opening the
container can be done in the normal stateless manner, once it is
opened, subsequent opens should only consider the container.

68a15d81de libstand's qdivrem.c assumes that sizeof(int) == sizeof(long), this is not
true on amd64 I'm not quite positive this is the "correct" solution for
this but it does seem to compile and shut up the spew of warnings when
compiling libstand for userboot.

Add two _Static_asserts() so that in the future somebody will get a compile
failure if an architecture develops that violates the assumptions of this
code. (strongly suggested by jmg)

Change commetns to indicate int types instead of long.  (noted by ian in

06622912a6 Set the malloc alignment to 64 bytes on platforms that use the U-Boot API
device drivers.  Recent versions of u-boot run with the MMU enabled, and
require DMA-based I/O to be aligned to cache line boundaries.

These changes are based on a patch originally submitted by Juergen Weiss,
but I reworked them and thus any problems are purely my fault.

566238caa7 Fix an inappropriate free of a non-dynamic value. While here, make the
code more naive and robust:
1.  When setting ev_value, also always set ev_flags appropriately
2.  Always check ev_value and ev_flags before calling free.

Both the value and the EV_DYNAMIC property can come directly from the
consumers of the environment functionality, so it's good to be careful.
And since this code is typically not looked at for long periods of
time, it's good to have it be a little "dumb-looking".

Trigger case for the bug:
        env_setenv("foo", 0, "1", NULL, NULL);
        env_setenv("foo", 0, "2", NULL, NULL);

2d8b3ad7fa libstand: Reset the seek pointer in ext2fs as done in UFS.
Based on r134760:

Reset the seek pointer to 0 when a file is successfully opened,
since otherwise the initial seek offset will contain the directory
offset of the filesystem block that contained its directory entry.
This bug was mostly harmless because typically the directory is
less than one filesystem block in size so the offset would be zero.
It did however generally break loading a kernel from the (large)
kernel compile directory.

Also reset the seek pointer when a new inode is opened in read_inode(),
though this is not actually necessary now because all callers set
it afterwards.

e7e5b53bf1 Replace index() and rindex() calls with strchr() and strrchr().
The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

6014007e00 Merge index() and strchr() together.
As I looked through the C library, I noticed the FreeBSD MIPS port has a
hand-written version of index(). This is nice, if it weren't for the
fact that most applications call strchr() instead.

Also, on the other architectures index() and strchr() are identical,
meaning we have two identical pieces of code in the C library and
statically linked applications.

Solve this by naming the actual file strchr.[cS] and let it use
__strong_reference()/STRONG_ALIAS() to provide the index() routine. Do
the same for rindex()/strrchr().

This seems to make the C libraries and static binaries slightly smaller,
but this reduction in size seems negligible.
