Compensate for src/common/lib/libc/atomic/atomic_init_cas.c losing
the extern declaration of __libc_atomic_init() and instead using a
new one added to src/lib/libc/include/extern.h

That file is outside src/common and src/sys so is unavailable to
kernel builds, so instead make a new include file in src/common
which the kernel can read which contains the needed extern decl
for __libc_atomic_init()

This seems to fix the evbarm builds (maybe others) - but it is
all MUCH TOO UGLY to keep. Someone please make a better fix,
even if that just means reverting rev 1.5 of
src/common/lib/libc/atomic/atomic_init_cas.c
and all of the changes here (the addition to libc/include/extern.h
should be harmless to keep).

- Add new "externalize to file" and "internalize from file" functions
to make reading a property list from a file and writing a property

calling an accessor for one object type with a different object type
as an argument will return a suitable "invalid" value.

with a NULL object.
- Externalized property lists now contain a reference to the Apple XML
plist DTD.

Improvements to the problib(3) API:

==> Provide a much more complete set of setters and getters for different
value types in the prop_array_util(3) and prop_dictionary_util(3)
functions.

==> Overhaul the prop_data(3), prop_number(3), and prop_string(3) APIs

awkward names, and produce link-time warnings when they are referenced.

==> Deprecate mutable prop_data(3) and prop_string(3) objects. The old

warnings when used.

==> When the new prop_string(3) API is used, strings are internally
de-duplicated as a memory footprint optimization.

==> Provide a rich set of bounds-checked gettter functions in and a
corresponding set of convenience setters in the prop_number(3) API.

Fix an implementation inconsistency with the prop_*_send_syscall() and
prop_*_recv_syscall() functions from proplib(3). They now share the
same logic as the one from prop_*_send_ioctl() functions:
- returns an int
- 0 indicates "no error", otherwise returns the error number (and
set errno)

Many consumers of the prop_*_{ioctl, syscall} expect errno to be set
on error and use err() to display the error message. As such, ensures that
errno gets set before returning from these functions.

prop_*_send_syscall() functions returned a boolean, and now return an int.
Fix all call sites to use the new paradigm (only quota2 is affected in src).

As the prop_*_{send,recv}_syscall() API appeared in -current and is only
used by the recent quota2 code, I am not bumping the lib. The API change
only affects the prop_*_send_syscall() function (recv_syscall()s were
already used correctly), so ensure you are not mixing "old" -current
quota binaries with a new proplib(3) (or the other way around). This
change will be announced via a HEADS-UP and UPDATING.

Does not affect the kernel part of proplib.

Document the correct API in prop_array(3) and prop_dictionary(3).

Add a new libquota library, which contains some blocks to build and/or
parse quota plists; as well as a getfsquota() function to retrieve quotas
for a single id from a single filesystem (whatever filesystem this is:
a local quota-enabled fs or NFS). This is build on functions getufsquota()
(for local filesystems with UFS-like quotas) and getnfsquota();
which are also available to userland programs.
move functions from quota2_subr.c to libquota or libprop as appropriate,
and ajust in-tree quota tools.
move some declarations from kernel headers to either sys/quota.h or
quota/quota.h as appropriate. ufs/ufs/quota.h still installed because
it's needed by other installed ufs headers.
ufs/ufs/quota1.h still installed as a quick&dirty way to get a code
using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of
ufs/ufs/quota.h - old code won't compile without this change and this is
on purpose).

- Add prop_dictionary_all_keys(). Takes a snapshot of a dictionary's
keys and returns them in an array. This effectively allows a caller
to mutate a dictionary while iterating over it (really, you iterate
over the array of keys instead of the dictionary itself).
- Add a slew of utility functions that make it more convenient (in some
circumstances, anyway) to get/set values in a dictionary.

Alter the protocol impemented by prop_kern to allow for bi-directional
plist-based messages and to eliminate looping previously required to
receive a plist from the kernel:

- prop_dictionary_copyin_ioctl() and prop_dictionary_copyout_ioctl()
now take the cmd argument rather than the file open flag. The
read-ness or write-ness of an ioctl command is checked by these
routines to ensure that information is being passed to/from the
userland component properly.

- prop_dictionary_copyout_ioctl() now allocates the memory for the
XML plist on behalf of the userland component by way of uvm_mmap().
The XML plist is copied out to the newly-mapped anonymous region,
and the pointer returned via the plistref.

- prop_dictionary_recv_ioctl() is responsible for munmap()'ing the
region after parsing the XML plist into internal represenatation.

- A new prop_dictionary_sendrecv_ioctl() is added, allowing user space
code to send a dictionary to the kernel and receive one back as a
reply.

- Add new "externalize to file" and "internalize from file" functions
to make reading a property list from a file and writing a property
list to a file more convenient.
- Many assertions in the object implementations are gone. Instead,
calling an accessor for one object type with a different object type
as an argument will return a suitable "invalid" value.
- prop_object_type() now returns a new PROP_TYPE_UNKNOWN value if called
with a NULL object.
- Externalized property lists now contain a reference to the Apple XML
plist DTD.
- Add a new prop_ingest(3) facility, which provides a convenient way to
translate a dictionary into an arbitrary binary representation.
