Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement. setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).
Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.
Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.
Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used. However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.
Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI. Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.

Instead of changing the whole course to another POSIX-permitted way
for consistency and uniformity I decide to completely ignore missing
regex fucntionality and focus on fixing bugs in what we have now,
too many small obstacles we have choicing other way, counting ports.
Corresponding libc changes are backed out in r302824.
Instead of trying to expand whole range at regcomp() stage as we do,
GNU regex allocates separate ranges [start,end] set each character
is checked against, so collation is possible and turned on for ranges here.
When something like that will be implemented or our obsoleted regex code
will be replaced to something like TRE, and in case we decide to use
collation in [a-z] ranges, all changes related to r302512 can be backed out,
but now we need consistency.

Summary of changes:
- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
namespacing is kept with FILES appropriately, and that this shouldn't need
to be repeated if the namespace changes -- only the definition of PACKAGE
needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
`tests`. In the event we get to the point where things can be split up
enough in the base system, it would make more sense to group the tests
with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)
Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

This is not properly respecting WITHOUT or ARCH dependencies in target/.

the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is

- Add a kvaddr_type to represent kernel virtual addresses instead of
unsigned long.
- Add a struct kvm_nlist which is a stripped down version of struct nlist
that uses kvaddr_t for n_value.
- Add a kvm_native() routine that returns true if an open kvm descriptor
is for a native kernel and memory image.
- Add a kvm_open2() function similar to kvm_openfiles(). It drops the
unused 'swapfile' argument and adds a new function pointer argument for
a symbol resolving function. Native kernels still use _fdnlist() from
libc to resolve symbols if a resolver function is not supplied, but cross
kernels require a resolver.
- Add a kvm_nlist2() function similar to kvm_nlist() except that it uses
struct kvm_nlist instead of struct nlist.
- Add a kvm_read2() function similar to kvm_read() except that it uses
kvaddr_t instead of unsigned long for the kernel virtual address.
- Add a new kvm_arch switch of routines needed by a vmcore backend.
Each backend is responsible for implementing kvm_read2() for a given
vmcore format.
- Use libelf to read headers from ELF kernels and cores (except for
powerpc cores).
- Add internal helper routines for the common page offset hash table used
by the minidump backends.
- Port all of the existing kvm backends to implement a kvm_arch switch and
to be cross-friendly by using private constants instead of ones that
vary by platform (e.g. PAGE_SIZE). Static assertions are present when
a given backend is compiled natively to ensure the private constants
match the real ones.
- Enable all of the existing vmcore backends on all platforms. This means
that libkvm on any platform should be able to perform KVA translation
and read data from a vmcore of any platform.

ld(1) uses the /usr/libdata/ldscripts when linking. These scripts add in the
default search paths of /lib and /usr/lib via 'SEARCH_DIR("DIR")'. These
need to be prefixed by '=' so that the --sysroot flag is respected. This
is not a problem with buildworld since the TOOLS_PREFIX is baked into the
cross-ld. However it is a problem when trying to use ld(1) with --sysroot
anywhere else as it ends up still reading /lib and /usr/lib despite --sysroot.
The default --sysroot (TARGET_SYSTEM_ROOT) is '/' for /usr/bin/ld.
I found this while building with META MODE with uses only --sysroot with
/usr/bin/ld, and found that libraries that I had not built in its sysroot
directory were leaking in. This didn't happen with ports binutils either. This
would also impact external compiler support.

In r204548 the 'rm -f ldscripts' was added likely due to reading the
conditional as 'else it is a file'. That seems unlikely though and
the more likely case is just that the directory hasn't been created yet.
Because this races with ,ssother scripts, use 'mkdir -p' which is a minimal
modification vs upstream to avoid the warning of 'File exists' if another
script creates it first. This could replace the 'test -d' as well but
then it's more unneeded change to the upstream script.

out of 'struct pcb' and into a variable-sized region after the

read in the FPU save area but instead passes stack garbage as the
FPU's saved context. Fixing this would mean determining the proper
size of the area and fetching it. However, this state is not saved
for running CPUs in stoppcbs[], so the callback would also have to
know to ignore those pcbs. Instead, just remove the call since it is
of limited usefulness. It results in kgdb reporting the state of the
FPU/SIMD registers in userland, not their current values in the kernel.
In particular, it does not report the correct state for any code in
