librumpxen_xendev: Re-enable build for xenbus, and add it to the default bake

Fixes issue #73 for the xenbus driver.

privcmd and evtchn are not fixed yet - they are still disabled.

issue #73

Fix installation of xen private components

xen: build rumpxen{dev,if} from Makefile, not build-rr

Makes the platforms consistent.

xen Makefiles: g/c flags set elsewhere

Put some common CFLAGS/CPPFLAGS into Makefile.inc

makefile: g/c leftover variable

clean clean targets in Makefiles

Build libs into objdir.

The grand implication of this commit is that now it's possible to
build both hw and xen from the same source tree (which is useful
mostly for me so that I can easily test things when developing).
nb. different target cpus are still not supported from the same
source tree.

Build libs into objdir.

Well, the ones built by platform/Makefile.inc, at any rate.

Consolidate the RUMPRUN_MKCONF include dance into global.mk

Convert all safe-looking locations, i.e. NOT app-tools
or platform/xen/xen.

create config.mk into objdir

platform/xen: don't override common TARGETS

fix xen/Makefile to work again

PLATFORM comes from config.mk, so g/c it from Makefiles.

Reduce copypasteware in Makefiles

Give app-tools its own Makefile instead of it being a .inc

This means that app-tools are now built directly by build-rr.sh
instead of being driven by platform/x/Makefile.

g/c APPTOOLS_OBJS_BAKE, it does not contain any extra info.

Install ldscript and use it for baking from destdir

Put ldscript in common place

Just create rumprun.o in the same place as hw

Need real objdir later (location via config.mk),
but go for the easy way now.

Install mainobj and use it from destdir in app-tools.

Note to devs: you must now "make && make install" in platform/foo

Include libbmk_{core,rumpuser} in $MAINOBJ.

Support kernonly mode for Xen

nb. tests/nolibc won't build for xen; hw is hardcoded there

one -nostdinc is enough

Destdir builds, part 1

Support a -d flag to build-rr.sh. Make some of the tools use
libraries and headers from that directory instead of a hardcoded
place.

Not everything is installed into destdir yet. More to come.

Restore Xen object order

Link minios.o into rumprun.o

Mirrors what platform/hw does.

xen: callmain.c -> init.c

Now both platforms have the same name for the module containing the
same functionality.

don't override correct OBJCOPY from config.mk

Link sysproxy component based on bake recipe, kill $topdir/config.mk

consistency rename: BAKEOBJS -> OBJS_BAKE

LDSCRIPT -> LDSCRIPT_BAKE (and remove LDSCRIPT from specs-stub)

Don't give a generic LDFLAGS to app-tools, just LDFLAGS_BAKE

Fold HEAD_OBJ and OBJS into BAKEOBJS.

Just give them in the right order, the first one is the first one.

Fix the --host parameter to build to include "elf" where appropriate

i.e. now i386-rumprun-netbsdelf, not just -netbsd

Build rumphyper_net.c as part of the interface component.

Wasn't easy earlier, still not easy, but at least somewhat possible.

update src-netbsd and switch to new-style pci build

Push buildtest to common Makefile.

Test baking with all known board configurations. Not sure it's a
supersmart idea to do it at this level, but not sure where else to do
it either.

push "make tests" into common makefileage

include ../Makefile.inc only once

Don't set TARGET_ARCH=${MACHINE}

GNU make uses TARGET_ARCH in implicit rules, and fails quite
badly with the above.

define LIBS_SYSPROXY in Makefile.inc

move more platform makefile bits to Makefile.inc

cleaning the common libs is a common job too

push some common bits from platform Makefiles into Makefile.inc

Introduce `rumpbake' for final linking of unikernels

As discussed on the mailing list:

- toolchain 'cc.in' produces an intermediate relocatable file, and
verifies the userspace link using a stub version of librumprun_base
and the minimal set of rump components.
- rumpbake is used to produce the final unikernel image, and supports
defining target configurations in rumpbake.conf.

push rumpconfig.c into librumprun_base

xen rumpconfig: Add support for IPv6 SLAAC

do the build lithmus test the new way

remove now-empty xen/rumphyper_base.c

Do not build tests by default in platform libs.

"make tests" can be specified explicitly. It will build and run
the tests.

fix pasto

Add an unconditionally run "buildtest"

Makes sure that just typing "make" attempts to link at least one
unikernel and expose really obvious problems with changes.

Force the common libs to always be built.

And by "always be built" I mean force the top-level build process to
consult the respective Makefiles to determine if the libs should be
rebuilt or not.

include tmpfs in the standard mix

Rename librumprun_rumpuser to libbmk_rumpuser

Layeristically speaking, the common rumpuser bits run on top of bmk,
so the renamed name now also reflects reality (and matches the
header namespace).

Rename librumprun_core to libbmk_core.

It doesn't have anything to do with rumprun, but is at a lower layer of
abstraction, so let's just match the header namespace here.

push libc_stubs to librumprun_base

move bio hypercalls from rumphyper_base to rumphyper_bio

xen now supports the test framework

convert tests to use librumprun_tester

Prune configure_stubs residuals in Makefile

But leave configure_stubs.c alone as Antti says it's useful for
revamp-mode.

Create librumprun_rumpuser, platform-independent rump kernel hypercalls

Seed with rumphyper_synch.c from platform/xen.

(and also convert /xen to use rumprun_rumpuser)

push common rumpuser hypercall stubs to bmk-core

push __errno.c to bmk-base

push the _lwp.c implementation to bmk-base

clean the right objdir

Use CPPFLAGS for cpp switches

clang throws an error if they're on link-line via CFLAGS since cpp is
not used at all in that invocation.

Build librumprun_{base,core} via the platform Makefiles.

They still don't have full dependencies, but at least now they
can be rebuilt with "make clean && make".

clean config.mk for platform/xen in "distcleanrump"

unify libc-level malloc wrappers to rumprun_base

convert platform/xen to rumprun_core memalloc

Use separate files for malloc backend and libc frontends

copypasted from /baremetal ... so that it's easier to uncopypaste
as the next step.

sensible layering drama, act 2

Convert easy cases of xen platform string routine use from libc to
bmk-string. There are a few harder-to-crack ones which use things
like strtotul. Need to see if those are really necessary, or can we do
without introducing those interfaces to the desirably minimal bmk-string.

convert xen to use buildrump.sh toolchain-conf.mk

collect some universal build flags into one place: global.mk

Make sure RUMP_LIBS_SYSPROXY is defined when we use it.

move platform-private sysproxy.c copies to rumprun_base

use --start-group for our platform libs (rumprun_base, pthread, c)

Remove private platform copies of the "emul" modules.

Add a common version to librumprun_base as syscall_misc.c
(the module provides some misc syscalls, so the new name is
more accurate)

make warning flags a bit more sensible, including -Werror

use -Werror

Build librumprun_base into an object directory

Using this cheap trick we can still play with both /baremetal
and /xen in the same tree.

Introduce librumprun_base

For now, it is meant to contain platform independent user-level routines.
Seed the lib with netbsd_initfini.c, which is the indentical netbsd_init.c
from both platforms.

Use APP_TOOLS_TARGETARCH instead of TARGET_ARCH

Not only is it easier to figure out why the variable is set, for whatever
reason, GNU make on my machine gets wildly confused if TARGET_ARCH is
set in baremetal/Makefile.

sensible layering drama, act 1

Do not include errno.h in modules which do not run on top of libc.

Just for clarity: libc = NetBSD libc. We do not have any other libc
in the stack.
