requiring the DRelease be able to fill a page when passed a pointer

pointer to data describing the page containing the address. The
directory code is free to play with the data pointer as it wishes,
as long as the private pointer to the page is passed through intact.

macos: bulkstat caller reference handling
if bulkstat is called and fakes up vnodes for non-dir cases, it can
guess wrong, and we end up needing to fix up the type by swapping
in a new vnode under the vcache. however, references are tracked on
the vnode, and more importantly, callers can know about the vnode;
unlinking a vcache from a vnode leaves null pointers to blow up on.
thing is, we shouldn't end up with a un-fixed-up vcache in use:
any caller of ProcessFS will notice if the vnode is the wrong type,
and fix it. so in order to reach CStatd, we have to fix it.
the only places where we can get a vcache in use not CStatd are:
FindVCache, LookupVCache, GetVCache where InReadDir. The last happens
only on Linux. LookupVCache doesn't happen anywhere that matters
(CForeign, or we immediately dispose...). FindVCache is only called
somewhere which won't lead to us fixing up during create, but that
vnode isn't returned to callers; we finalize in the result of create
and return the vnode that's linked to the vcache, which will be correct.
so, the only other place we can have a reference which won't immediately
get fixed up is in lookup, across the bulkstat call. if that's true,
and we return from bulkstat a non-CStatd vcache, lookup will fill in the
entry manually. so, if there are references remaining after we do a fixup,
unmark CStatd so the caller (presumably lookup, given the above) will give
back the vcache and retry, getting a corrected vnode as a result, with
the reference on the vnode we want it on.

exceed the configured -stat level, we will always keep trying to flush
numerous vcaches, even if we barely have any vcaches in use.
Add a more complete usage message to runtests and add support for a -h
command-line flag to display the usage message.
is_double() now takes a third argument, an epsilon. Two numbers are
considered equal if their absolute difference is less than epsilon.
is_double() also now treats wanted and seen values of NaN (not a
number) as equal. Thanks to PICCA Frédéric-Emmanuel for the proposed
changes.
The ok_program function in the shell libtap.sh library no longer
strips text after a colon and a space from the program output if the
expected status is non-zero. Instead, if program output may contain
system-specific error messages after a colon and a space, put the new
function strip_colon_error before the program to do this stripping.
Thanks to Carsten Hey for the idea.
strip_colon_error is now smarter about preserving an initial word
ending in a colon (which is generally the program name) while still
stripping error messages later in the line.
The test_file_path function in the shell libtap.sh library now always
returns the empty string, rather than possible absolute paths starting
at /, if $BUILD and $SOURCE are not set.
Flush standard error in the C TAP library before printing results for
more deterministic output. Thanks to Carsten Hey for the idea.
All of C TAP Harness now compiles with gcc -ansi -pedantic and should
be fully C89-compatible. Note that either C99 or SUSv3 is required to
build C TAP Harness. (This should not be a problem on any modern
platform.) Based on work by Carsten Hey.
Simplify and improve output formatting in the summary of failing tests
in some edge cases.
Add explicit license statements to the files meant to be copied into
other packages rather than referring to LICENSE.
Add a test_file_path() function to the basic C and shell TAP
libraries, which searches the build and source directories for a
particular file and returns the full path. This is a utility function
that can be used to find test data files.
The cmd/command-t test requires libroken and was misspelled in the
TESTS file. Multiple tests require LD_LIBRARY_PATH to be set to find
libafsroken if it hasn't been installed, so set it when running
runtests via make check. (Note that this means runtests -o will not
work properly unless the user also sets LD_LIBRARY_PATH.)

viced: Avoid ref leak on origin callback break
When breaking a callback, sometimes we send a callback to the host
that performed the callback-inducing operation. When we do this,
currently BreakCallBack gives the origin host structure to
MultiBreakCallBack_r, which avoids releasing that host after the
callback is broken.
However, BreakCallBack obtains a reference to every host to which it
delivers a callback, even if it is the origin host, so a reference is
leaked. Fix this by not ever passing a host to MultiBreakCallBack_r,
and just have MultiBreakCallBack_r release a reference for every host
to which it delivers a callback break.

viced: Transfer host ref in h_FindClient_r
In h_FindClient_r, we can change which client structure we're dealing
with if we find a different client struct in the Rx conn-specific
data. We adjust the refcounts for the client structures themselves,
but not the associated hosts. While the host structures should be the
same most of the time, we are not guaranteed that, so adjust their
refcounts as well.

cmd: Support splitting switches and values with '='
Some of our code uses arguments of the form -name=value. Add support
to libcmd for dealing with this type of argument, where name is
declared as CMD_SINGLE (or CMD_SINGLE_OR_FLAG)
