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.

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.
Prefer %zu to %ju for size_t.

Unset PWD if it is incorrect and no value for it can be determined.
This preserves the logical current directory across shell invocations.
Example (assuming /home is a symlink):
$ cd
$ pwd
/home/foo
$ sh
$ pwd
/home/foo
Formerly the second pwd would show the physical path (symlinks resolved).
Current versions pass this test trivially by never importing PWD, but I plan
to change sh to import PWD if it is an absolute pathname for the current
directory, possibly containing symlinks.
This applies to word in ${v-word}, ${v+word}, ${v=word}, ${v?word} (which
inherits quoting from the outside) and in ${v%word}, ${v%%word}, ${v#word},
${v##word} (which does not inherit any quoting).
In all cases tilde expansion is only attempted at the start of word, even if
word contains spaces. This agrees with POSIX and other shells.
This is the last part of the patch tested in the exp-run.

Note that this depends on r206145 for allowing pattern match characters to
have their special meaning inside a double-quoted expansion like "${v%pat}".

* remove the backslash from \} inside double quotes inside +-=?
substitutions, e.g. "${$+\}a}"
* maintain separate double-quote state for ${v#...} and ${v%...};
single and double quotes are special inside, even in a double-quoted
string or here document
* keep track of correct order of substitutions and arithmetic
This is different from dash's approach, which does not track individual
double quotes in the parser, trying to fix this up during expansion.
This treats single quotes inside "${v#...}" incorrectly, however.
This is similar to NetBSD's approach (as submitted in PR bin/57554), but
recognizes the difference between +-=? and #% substitutions hinted at in
POSIX and is more refined for arithmetic expansion and here documents.

(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.

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
# the machine (which would be more appropriate). NANO_ARCH smashes the two
# together right now.

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.

Redirection errors on subshells already did not abort the shell because
the redirection is executed in the subshell.
Other shells seem to agree that these redirection errors should not abort
the shell.
Also ensure that the redirections will be cleaned up properly in cases like
command eval '{ shift x; } 2>/dev/null'
Example:
{ echo bad; } </var/empty/x; echo good
- A couple of tests to check if the layout of the generated calenders
is correct.
- A couple of tests to see if impossible combinations for -3, -A,
-m, -y etc properly abort.
- A couple of test to confirm that the order of -A, -B, -3 etc give
the right number of months.
Although simple commands without a command word (only assignments and/or
redirections) are much like special builtins, POSIX and most shells seem to
agree that redirection errors should not abort the shell in this case. Of
course, the assignments persist and assignment errors are fatal.
To get the old behaviour portably, use the ':' special builtin.
To get the new behaviour portably, given that there are no assignments, use
the 'true' regular builtin.
We currently ignore readonly status for assignments before regular builtins
and external programs (these assignments are not persistent anyway), so just
check that the readonly variable really is not changed.
The test depends on the command builtin changes for 'command :'.
These expansions, which were already in the Bourne shell, work correctly for
the most part. The testcases are only about the parts that already work
correctly.
They are mainly about expansions in here documents but because all the
testcases are in $() command substitution, we also test that $() command
substitution is recursively parsed (or very close to it).
* avoid unnecessary fork
* allow executing builtins via command
* executing a special builtin via command removes its special properties

snprintf(3) doesn't set errno in the tested cases.
- If the same argument reference (for example %1) was specified more than
once, the command didn't necessarily fit to the final command buffer. Fix
this using a dynamic sbuf buffer. Add a few regression tests for the case.
