Removing the panic leads to exactly one message on ALIX. Both commits
make minix out of the box booting on ALIX devices.

Seems like its a kind of convention introduced by Intel but not
mandatory from a PCI specification point of view, that the PCI host
controller resides on bus 0, device 0 function 0. At least tinybios
(the bios used by ALIX and WRAP) based appliances are not able to boot
with this change.

Bad logic introduced as part of the fsdriver changes could cause
getdents to terminate early in these libraries.

We already had a hack to ignore the precision, but the ACPI driver
requires an actual implementation--it prints garbage at the end of
some strings otherwise. This patch adds support for precision for
strings only, limiting printing to the given number of characters.
For all other specifiers, precision is still unsupported.

Previously, the bootloader would only provide a single memory range.
At least on VirtualBox, this memory range includes the ACPI tables,
which the kernel then happily overwrites when executing VM. Much of
the infrastructure to use a fullblown memory map is already in place;
this patch adds the last (and strangely missing) bit of generating
the memory map in a multiboot-compatible way.
It should be noted that both the bootloader and the kernel actually
violate the multiboot specification by not packing the structure for
the memory ranges. This is a NetBSD bug, but it is also a nonissue
for (our) practical purposes. It can be fixed without changing the
code added in this patch.

The original one-shot page patch (git-e321f65) did not account for the
possibility of pagefaults happening while copying memory in the
kernel. This allowed a simple cp(1) from vbfs to hang the system,
since VM was repeatedly requesting the same page from the file system.
With this fix, VM no longer tries to fetch the same memory-mapped page
from VFS more than once per memory handling request from the kernel.
In addition to fixing the original issue, this change should make
handling memory somewhat more robust and ever-so-slightly faster.
Test74 has been extended with a simple test for this case.

This allows the URL used to clone our specific version of u-boot to be
specified in the environment, instead of being hard-coded.
This new flexibility will be required by the new Continuous Integration
infrastructure, whose test nodes are in a network without direct
internet access.

. bitcode fixes
. switch to compiler-rt instead of netbsd libc functions
or libgcc for support functions for both x86 and arm
. minor build fixes
. allow build with llvm without crossbuilding llvm itself
. can now build minix/arm using llvm and eabi - without C++
support for now (hence crossbuilding llvm itself is turned off
for minix/arm)

- Expose in procfs the service status and supported recovery policies.
- This adds a test (testrelpol.sh) to exercise the restart policies of
the system services and drivers.
NOTE:
The policy support information is temporarily hardcoded in ProcFS, but
this has to be replaced by properly retrieving this information from
RS, which should in turn be setup on a per service basis, at
initialization time.

The new implementation of this library provides abstractions for
network drivers, and should be used for all network drivers from now
on. It provides the following functionality:
- a function call table abstraction, hiding the details of the
datalink protocol with simple parameters;
- a state machine for sending and receiving packets, freeing the
actual driver from keeping track of pending requests;
- an abstraction for copying data from and to the network driver,
freeing the actual driver from dealing with I/O vectors while at
the same time providing a copy implementation which is more
efficient than most current driver implementations;
- a generalized implementation of zero-copy port-based I/O;
- a clearer set of policies and defaults.
While the concept is very similar to lib{block,char,fs,input}driver,
one main difference is that libnetdriver now also takes care of SEF
initialization, mainly so that aspects such as recovery policies and
live-update aspects can be changed for all network drivers in a
single place. As always, for the case that the provided message loop
is too restrictive, a set of more low-level message processing
functions is provided.
The netdriver API has been designed so as to allow alleviation of one
current protocol bottleneck: the fact that at most one send request
and one receive request may be pending at any time. Changing this
aspect will however require a significant rewrite of libnetdriver,
and possibly debugging of drivers that are not able to cope with (in
particular) queuing multiple packets for transmission at once.
Beyond that, the design of the new API is based on the current
protocol, and may be changed/extended later to allow for non-ethernet
network drivers, exposure of link status, multicast address
configuration, suspend and resume, and any other features that are in
fact long overdue.

This is required for at least QEMU. However, as of writing, QEMU also
requires fixes in its epro100 emulator before this driver can use it.

Bochs has switched from port base 0x240 to 0x300 for its default
NE2000 ISA configuration, and QEMU is using the same settings.

The expected argument name would include the instance number, which
is not only redundant in many cases (FOOETHn_n=arg.., "n" being the
instance number) and conflicted with what netconf(8) does, but some
drivers need to be able to see the arguments for all instances of its
driver type--for example, dp8390 needs to know how many earlier
instances have been configured to use PCI.

Previously, a TCP option length of zero would cause inet to end up
in an infinite loop.

After importing the default environment from NetBSD, we discovered that
it doesn't contain /usr/games, which is required for the commands
strfile. This utility is used while generating fortune database.
This patch simply sets TOOL_STRFILE to contain an absolute path.
