kernel - Add support for MosChip PCIe serial com, and console support
* Add support for the MosChip PCIe serial com (brand is typically
'StarTech' 'Natikve PCI Express RS232 serial adapter card with
16550 UART'.
* Add late console support. Console operation works the same
way, set it up in /boot/loader.conf. Typically:
sio0.flags=0x00
sio4.flags=0x30
sio4.baud=115200
#set boot_serial="YES" <-- commented out, do not set this
Note that at the point a late-configured serial port
wants to become the console, syscons is probably already
the console, so you have to use flags 0x30 instead of
0x10 to force it to change the console.
* Note, you do not have to set boot_serial="YES", because it
won't really help since the adapter isn't accessible to the
boot loader or to the kernel until the PCIe device probes
in the middle of the boot sequence.
* The kernel now retests for consoles at the end of its normal
configuration sequence, which allows the now-available
sioN devices from PCIe card(s) to become the console.
* Remove syscons sccnterm() code that tried to undo the syscons
console designation. This code was never called in the past
because the system console couldn't actually change once
selected. But now it can, and the code completely blows up
syscons for numerous reasons. Just leave the console
designation intact from syscons's point of view (the main
system will be vectored elsewhere so syscons will simply
not receive new kernel console reads and writes).
* Add a siocntxwait() call before changing com parameters,
since we are potentially changing the baud rate here.
* Change how the SIO driver assigns baud rates for the console
to handle late-console configurations. Also, allow sio*.baud
variables in loader.conf to override the default com rate.
* Add entries for com5 and com6 to /etc/remote, and default to
a more reasonable baud rate of 115200.

* Fixes rare panics when e.g. removing large numbers (as in hundreds of

but does not prevent another thread from locking it and issuing
hammer2_chain_modify().

especially chain->data and chain->dio, by adding an interlock between
frontend access to the data and backend hammer2_chain_modify() calls.
Held but unlocked chains are used by the XOP API to pass chains back to
the frontend.
* Remove the automatic (because it is unsafe) dio synchronization
in hammer2_xop_collect() and instead implement an API that the
frontend can use to safely access the data. The API is
hammer2_xop_gdata()/hammer2_xop_pdata().
* Remove the unsafe hammer2_cluster_rdata(). Use gdata/pdata for this

buildworld: Add support to skip toolchain if requested.
These two new features are mainly aimed at developers, to speed up their
rebuilds on development branches. Often there are no changes that would
influence the toolchain components in any way. So it is reasonable to
skip rebuild of certain parts (mostly to avoid building c++ sources).
Previously we were rebuilding both main and alternative compilers twice
during buildworld for a full bootstrap that allowed us to avoid certain
breakages and not to keep adding lots of backwards compatibility hacks.
The new additions:
* -DNO_CROSSTOOLS - skip compiler and binutils bootstrap;
* -DNO_TOOLCHAINS - do not build compilers/binutils for installworld.
Both features are aimed for testing DESTDIR targets. Decision to
activate any of these features is left to the user's own discretion
based on reviewing the commits to the git repository or local clone.
The NO_CROSSTOOLS feature is implemented by installing the shell script
wrappers that add a sysroot and patch the specs. Idea is not to disturb
in any way the Makefile.inc1 or objformat logic at this moment. Since
all the main toolchain tools are installed as shell scripts this has a
nice bonus for quick hooks/probes and other hacky/pretty stuff without
disturbing the rest of the buildworld. You can even add your favorite
static analyser tool, just don't forget to change default include path
to /usr/obj/../world_x86_64/usr/include for it.
The objformat changes for sysroot would only make sense when we make a
port for another architecture. None of the new features are considered
to be guessTM enabled automatically at this moment. To be sure that
nothing has changed since previous buildworld from other changes in the
source tree one would have to compile and hex-diff the final products.
Keep in mind that libraries coming with the compilers will be rebuilt
even with both knobs passed. This should help catching most of the
issues before installworld step and not on the next {build,quick}world.
Both knobs are not documented in make.conf(5) on purpose. It is highly
advised *not* adding any of these knobs into make.conf, sooner or later
you will forget it and *will* get yourself in world recovery situation:
a) world backup machinery (unless you had NO_BACKUP=true in make.conf);
b) perform manual bootstrap to fix up the breakage;
c) restore from H1/H2 snapshots (toolchain components are located in
/usr/libexec/* and /usr/lib/${CCVER}/ directories);
d) clean overwrite by mounting from other system (like usb img stick).
Features should work with quickworld too.

gcc80: Remove throw() from protos in libstdc++ headers.
The throw() as dynamic exception specificators was deprecated in c++11
and removed in c++17 (empty was made as an alias to noexcept(true)).
Our libc headers does not have the __attribute__(__nothrow__) markups.
To make libstdc++ fully usable for clangs on DragonFly it makes sense
to just remove the throw() additions in c++ language binding headers.
Previously in gcc50 we were excluding them just for __clang__ case as in:
