build FreeBSD virtual machine disk images for use on
the Microsoft Azure service.
For now, this target is not directly connected to the
build, however can be manually invoked.
The 'vm-azure' target invokes {amd64,i386}/mk-azure.sh,
which does the heavy lifting to produce proper VHDs.
mk-azure.sh uses a configuration file, defaulting to
tools/azure.conf if otherwise unset.

Previous logic was not differentiating disconnected LUNs and absent targets.
That made it to stop scan if LUN 0 was not found for any reason. That made
problematic, for example, using iSCSI targets declaring SPC-2 compliance and
having no LUN 0 configured.
The new logic continues sequential LUN scan if:
-- we have more configured LUNs that need recheck;
-- this LUN is connected and its SCSI version allows more LUNs;
-- this LUN is disconnected, its SCSI version allows more LUNs and we
guess they may be connected (we haven't scanned first 8 LUNs yet or
kern.cam.cam_srch_hi sysctl is set to scan more).

Instead requeue mbuf back to IPv4 protocol handler. If there is one extra IP-IP
encapsulation, it will be handled with tunneling interface. And thus proper
interface will be exposed into mbuf's rcvif. Also, tcpdump that listens on tunneling
interface will see packets in both directions.

It defines a variable and its default value in load_rc_config() just after
rc.conf is loaded. "rcvar" command shows the current and the default values.
This is an attempt to solve a problem that rc.d scripts from third-party
software do not have entries in /etc/defaults/rc.conf. The fact that
load_rc_config() reads rc.conf only once and /etc/rc invokes the function
before running rc.d scripts made developers confused for a long time because
load_rc_config() just before run_rc_command() in each rc.d script overrides
variables only when the script is directly invoked, not from /etc/rc.
Variables defined in set_rcvar are always set in load_rc_config() after
loading rc.conf. An rc.d script can now be written in a self-contained
manner regarding the related variables as follows:
---
name=foo
rcvar=foo_enable
set_rcvar foo_enable YES "Enable $name"
set_rcvar foo_flags "-s" "Flags to $name"
...
load_rc_config $name
run_rc_command "$@"

that keeps track of a particular region of the image. In particular the
image_data() function needs to return to the caller whether a region
contains data or is all zeroes. This required reading the region from
the temporary file and comparing the bytes. When image_data() is used
multiple times for the same region, this will get painful fast.
With a chunk describing a region of the image, we now also have a way
to refer to the image provided on the command line. This means we don't
need to copy the image into a temporary file. We just keep track of the
file descriptor and offset within the source file on a per-chunk basis.
For streams (pipes, sockets, fifos, etc) we now use the temporary file
as a swap file. We read from the input file and create a chunk of type
"zeroes" for each sequence of zeroes that's a multiple of the sector
size. Otherwise, we allocte from the swap file, mmap(2) it, read into
the mmap(2)'d memory and create a chunk representing data.
For regular files, we use SEEK_HOLE and SEEK_DATA to handle sparse files
eficiently and create a chunk of type zeroes for holes and a chunk of
type data for data regions. For data regions, we still compare the bytes
we read to handle differences between a file system's block size and our
sector size.
After reading all files, image_write() is used by schemes to scribble in
the reserved sectors. Since this never amounts to much, keep this data
in memory in chunks of exactly 1 sector.
The output image is created by looking using the chunk list to find the
data and write it out to the output file. For chunks of type "zeroes"
we prefer to seek, but fall back to writing zeroes to handle pipes.
For chunks of type "file" and "memoty" we simply write.
The net effect of this is that for reasonably large images the execution
time drops from 1-2 minutes to 10-20 seconds. A typical speedup is about
5 to 8 times, depending on partition sizes, output format whether in
input files are sparse or not.
Bump version to 20141001.
This has the side effect of ensuring that realpath is also run for the
nominal case of PORTSDIR=/usr/ports (assuming .CURDIR is a ports directory
that relies on /usr/ports but is not rooted in it). This ensures that any
generated PORTSDIR used is always the actual location.
