Merge @176820, @176822, @177156 to tcpp from P4 to HEAD:
Improve accuracy of connection data transfer math.
Disable Nagle's algorithm to avoid delaying transfers of data --
will want to refine this to combine payload with header transfer,
however.
Now that we're running w/o Nagle, try to send the initial data
burst with the header in a single TCP segment.

IEEE Std 1003.1, 2004 Edition states:
"The escape sequence '\n' shall match a <newline> embedded in
the pattern space."
It is unclear whether this also applies to a \n embedded in a
character class. Disable the existing handling of \n in a character
class following Mac OS X, GNU sed version 4.1.5 with --posix, and
SunOS 5.10 /usr/bin/sed.

The transition to Subversion allows us to rename files without
repo-copy hacks.
Remove the test-number prefix from the name of the output files,
so that new test cases can be easily added.
These are git commits 36f0fa8fcbc8c7b2b194addd29100fb40e73e4e9 and
d6d06ff5c2ea0fa44becc5ef4340e5f2f15073e4 in dash.
Because this is the first code I'm importing from dash to expand.c, add the
Herbert Xu copyright notice which is in dash's expand.c.
When pathname expanding *\/, the CTLESC representing the quoted state was
erroneously taken as part of the * pathname component. This CTLESC was then
seen by the pattern matching code as escaping the '\0' terminating the
string.
The code is slightly different because dash converts the CTLESC characters
to backslashes and removes all the other CTL* characters to allow
substituting glob(3).
The effect of the bug was also slightly different from dash (where nothing
matched at all). Because a CTLESC can escape a '\0' in some way, whether
files were included despite the bug depended on memory that should not be
read. In particular, on many machines /*\/ expanded to a strict subset of
what /*/ expanded to.
Example:
echo /*"/null"
This should print /dev/null, not /*/null.

I'm committing the generated files because I don't like a build dependency

Add a TestFloat based test suite for floating-point implementations
currently supporting sparc64. After a `make depend all` there are
three programs; testsoftfloat for testing against the SoftFloat in
src/lib/libc/softfloat for reference purposes, testemufloat for
testing the emulator source in src/lib/libc/sparc64/fpu and testfloat
for testing with the installed libc. Support for other architectures
can be added as needed.

Two fixes:
(1) We don't need a custom install_kernel. We can install without
symbols by adding INSTALL_NODEBUG (which likely should be
WITHOUT_KERNEL_SYMBOLS_FILE, or something shorter) to CONF_INSTALL
(2) for make buildenv stage, use NANO_MAKE_CONF_BUILD rather than the
non-existant NANO_MAKE_CONF.

Stop hard coding i386 as the arch for the build. Instead, default to the
processor we're running on. Also, supply amd64 version of create_diskimage
that's the same as i386's.
# didn't fix the confusion between using the processor for this and using

- When we run our trap cleanup handler, echo that we are running this
handler to make it more clear why we are 'suddenly' running df,
umount, and mdconfig.
- Remove trap handler again after we have unconfigured the memory

later stage failed, which was a bit confusing and not really useful.

Remove GNU cpio after fix of CVE-2010-0624.
Note that this is actually a no-op for most users, as this GNU
cpio was broken on -HEAD and 8-STABLE since last March until
the recent fix.
FreeBSD 8.0+ uses BSD cpio by default and the code is being
actively maintained.
Various testcases that work correctly with stable/8 sh.
Note: this creates some gaps in the numbering due to lower-numbered tests

The devices that supported EVFILT_NETDEV kqueue filters were removed in
r195175. Remove all definitions, documentation, and usage.
The change of function signature for vlan_link_state() was not merged to
maintain the ABI.
The gaps in the numbering sequence cannot really be avoided, as HEAD changes
are not necessarily merged in the same order as they are made (if they are
merged at all).

- Update config to doxygen 1.5.2 (I use this with 1.5.9).
- Add linprocfs and linsysfs to the linuxulator dox.
- Take the generated includes from the .m files from a subdirectory
instead of putting everything into $(.OBJDIR). This imporves the
human readbility of the source directory contents a lot, if you do not
create a separate OBJDIR.
- Assume UTF-8 encoding for every input file.
- Strip the source and dest path from the output, we are not interested
in the absolute location on the machine where the docs are created,
relative the the root of the FreeBSD source is what interests us.
- Exclude .svn directories.
- Switch to alphabetic index.
- Use one line per INCLUDE_PATH member in the common dox-config.
- Bump the __FreeBSD__ version to 9. [here in the MFC: to 8]
- Switch from hardcoded .m files to an run-time generated one. Takes
a little bit more time to get started with actual work, but at least
is more future-proof. If you generate dox for all subsystems, the
time to find all .m files in the source is magnitutes lower than
producing the docs.
- Make the *DEST_PATH overidable from the environment. This allows to
produce the output directly in the docroot of a webserver.
- Fix the path when telling the user where he can find the API docs.

Fix the conformance of poll(2) for sockets after r195423 by
returning POLLHUP instead of POLLIN for several cases. Now, the
tools/regression/poll results for FreeBSD are closer to that of the
Solaris and Linux.
Also, improve the POSIX conformance by explicitely clearing POLLOUT
when POLLHUP is reported in pollscan(), making the fix global.

Fix poll() on half-closed sockets, while retaining POLLHUP for fifos.
This reverts part of r196460, so that sockets only return POLLHUP if both
directions are closed/error. Fifos get POLLHUP by closing the unused
direction immediately after creating the sockets.
The tools/regression/poll/*poll.c tests now pass except for two other
things:
- if POLLHUP is returned, POLLIN is always returned as well instead of
only when there is data left in the buffer to be read
- fifo old/new reader distinction does not work the way POSIX specs it

Bugfix: all requests for creating vnets via vimage -c were always
reported as failures, even if the actual library / system call
would succeed, because error message would be reported if the return
value from jail_setv() call was >= 0, and if not, then if that same
value was < 0, i.e. always. The correct behavior is to abort (only)
if jail_setv() returns < 0.

vimage(8) is a legacy CLI interface for managing jails associated with
network stack instances, which is provided for compatibility with
older applications. This change brings it back to life in a followup
to the initial conversion of vimage to use the new jail(4)
userland-kernel API:
- when creating vimages via "vimage -c", by default turn on a few
options expected by legacy applications, such as allow operations on
raw sockets, FS mounts etc, and allow jail-related parameters to be
optionally configured.
- introduce the "-m" modifier which allows for configuring jail
parameters of existing vimages / vnet-jails.
- make "vimage name command ..." actually work.
- when reassigning ifnets to vnets using "vimage -i", attempt to rename
the ifnet as "ethXXX" on arrival in the target vnet. Several legacy
applications are known to depend heavily on such behavior.
- vimage -l lists only jails associated with vnets. The output is
sorted using vimage / jail names as keys.
- vimage -l by default searches only the current level in the jail
hierarchy. Recursive listing can be requested via -r switch.
- vimage -l by default prints only jail names on each line, making
such output suitable for pipelining to other commands. More verbose
output can be obtained via -v switch, and even more jail specific
information will be displayed if -j switch is turned on.
- there's no need to build vimage as statically linked, so update the
Makefile accordingly.
- update the vimage.8 man page.
