a160cbfa07 DIRDEPS_BUILD: libgcc now depends on MK_LLVM_LIBUNWIND
The dependency on gnu/lib/libgcc or lib/libgcc* is determined
at 'make dirdeps' time.

83f4f35130 Follow-up r320149: Enable GPL_DTC if we're using GCC as the cross-compiler.
This fixes object files landing in the source tree in gnu/usr.bin/dtc
for GCC platforms.

We cannot reliably detect if an external compiler is used here, and the
default YES option does include GCC_BOOTSTRAP which implies that GCC may
be used for the build.

The problem manifests when not using an external compiler, and the host
compiler is clang.  When a fresh build is done (no OBJDIR yet) the
'make obj' treewalk is done before 'make cross-tools', so
COMPILER_FEATURES at this point contains 'c++11' since the host compiler
was used for COMPILER_FEATURES.  Once cross-tools builds the GCC
bootstrap compiler and then descends into 'make everything',
COMPILER_FEATURES no longer contains 'c++11' and MK_GPL_DTC defaults to
enabled.  Now it builds in gnu/usr.bin/dtc without an OBJDIR preset and
drops files into the source tree.

The COMPILER_FEATURES check here is useful for knowing if we can *bootstrap*
C++11 things.  Indeed we do bootstrap dtc as a build tool so it is
useful for enabling the BSD dtc for the build, but we end up needing the
GPL dtc for installation anyway.

5bd47cc56f Change native-xtools to not install by default; add a native-xtools-install.
Without this the user has to mess with 'make -f Makefile.inc1 ...' to figure
out where the files are installed in the OBJDIR and then they need to copy them
to where they really wanted them. Using DESTDIR may be problematic after
r325001 as well.

The files will be installed to DESTDIR/NXTP where NXTP defaults to /nxb-bin.

1170c2fecc Implement IPMI support for RB_POWRECYCLE
Some BMCs support power cycling the chassis via the chassis control
command 2 subcommand 2 (ipmitool called it 'chassis power cycle').  If
the BMC supports the chassis device, register a shutdown_final handler
that sends the power cycle command if request and waits up to 10s for
it to take effect. To minimize stack strain, we preallocate a ipmi
request in the softc. At the moment, we're verbose about what we're
doing.

64a16434d8 Add support for compressed kernel dumps.
When using a kernel built with the GZIO config option, dumpon -z can be
used to configure gzip compression using the in-kernel copy of zlib.
This is useful on systems with large amounts of RAM, which require a
correspondingly large dump device. Recovery of compressed dumps is also
faster since fewer bytes need to be copied from the dump device.

Because we have no way of knowing the final size of a compressed dump
until it is written, the kernel will always attempt to dump when
compression is configured, regardless of the dump device size. If the
dump is aborted because we run out of space, an error is reported on
the console.

savecore(8) is modified to handle compressed dumps and save them to
vmcore.<index>.gz, as it does when given the -z option.

A new rc.conf variable, dumpon_flags, is added. Its value is added to
the boot-time dumpon(8) invocation that occurs when a dump device is
configured in rc.conf.

4f2fac3759 Improve computation of {BC,LL}OBJS.
Now that OBJS has grown an OBJS_SRCS_FILTER variable, use this variable
in the computation of BCOBJS and LLOBJS too. Also move BCOBJS and LLOBJS
computation to be next to the OBJS computation: this should both make
the parallel structure clearer and serve to remind people changing OBJS
that parallel changes are required in BCOBJS and LLOBJS.

A side effect of this change is that BCOBJS and LLOBJS will be available
even when LLVM_LINK has not been defined, but that seems like a positive
change: there's no reason we can't ask "what bitcode files would you
generate" just because we can't link those files together into a
complete bitcode representation of a binary or library.

e8fd18f306 Shorten list of arguments to mbuf external storage freeing function.
All of these arguments are stored in m_ext, so there is no reason
to pass them in the argument list.  Not all functions need the second
argument, some don't even need the first one.  The second argument
lives in next cache line, so not dereferencing it is a performance
gain.  This was discovered in sendfile(2), which will be covered by
next commits.

The second goal of this commit is to bring even more flexibility
to m_ext mbufs, allowing to create more fields in m_ext, opaque to
the generic mbuf code, and potentially set and dereferenced by
subsystems.

fc09164658 Restore the ability to deregister an eventhandler from within the callback.
When the EVENTHANDLER(9) subsystem was created, it was a documented feature
that an eventhandler callback function could safely deregister itself. In
r200652 that feature was inadvertantly broken by adding drain-wait logic to
eventhandler_deregister(), so that it would be safe to unload a module upon
return from deregistering its event handlers.

There are now 145 callers of EVENTHANDLER_DEREGISTER(), and it's likely many
of them are depending on the drain-wait logic that has been in place for 8
years. So instead of creating a separate eventhandler_drain() and adding it
to some or all of those 145 call sites, this creates a separate
eventhandler_drain_nowait() function for the specific purpose of
deregistering a callback from within the running callback.
