- Use KERNCONFDIR with KERNCONF instead of copying the kernel config into the source tree
so included kernel configs work.
- Put more stuff in the _.bk/_.ik log file, not just make statements.
- Add the kernel config name to the pprint during kernel installation.
- Add NANO_MODULES providing a list of modules to build and install.

This moves the function of the noaliases variable into the checkkwd
variable. This way it is properly reset on errors and aliases can be used
normally in the commands for each case (the case labels recognize the
keyword esac but no aliases).
The new code is clearer as well.

Apart from detecting breakage earlier or at all, this also fixes a segfault
in the testsuite. The "handling" of the breakage left an invalid internal
representation in some cases.
Examples:
echo a; do echo b
echo `) echo a`
echo `date; do do do`

subevalvar() incorrectly assumed that CTLESC bytes were present iff the
expansion was quoted. However, they are present iff various processing such
as word splitting is to be done later on.
Example:
v=@$e@$e@$e@
y="${v##*"$e"}"
echo "$y"
failed if $e contained the magic CTLESC byte.

The code is inspired by NetBSD sh somewhat, but different because we
preserve the old Almquist/Bourne/Korn ability to have an unquoted part in a
quoted ${v+word}. For example, "${v-"*"}" expands to $v as a single field if
v is set, but generates filenames otherwise.
Note that this is the only place where we split text literally from the
script (the similar ${v=word} assigns to v and then expands $v). The parser
must now add additional markers to allow the expansion code to know whether
arbitrary characters in substitutions are quoted.
Example:
for i in ${$+a b c}; do echo $i; done

If double-quote state does not match, treat the '}' literally.
This ensures double-quote state remains the same before and after a
${v+-=?...} which helps with expand.c.
It makes things like
${foo+"\${bar}"}
which I have seen in the wild work as expected.

This is a syntax error.
POSIX does not say explicitly whether defining a function with the same name
as a special builtin is allowed, but it does say that it is impossible to
call such a function.
A special builtin can still be overridden with an alias.
This commit is part of a set of changes that will ensure that when
something looks like a special builtin to the parser, it is one. (Not the
other way around, as it remains possible to call a special builtin named
by a variable or other substitution.)

Add some conservative checks on function names:
- Disallow expansions or quoting characters; these can only be called via
strange control characters
- Disallow '/'; these functions cannot be called anyway, as exec.c assumes
they are pathnames
- Make the CTL* bytes work properly in function names.
These are syntax errors.
POSIX does not require us to support more than names (letters, digits and
underscores, not starting with a digit), but I do not want to restrict it
that much at this time.

This is how ksh93 treats ! within a pipeline and makes the ! in
a | ! b | c
negate the exit status of the pipeline, as if it were
a | { ! b | c; }
Side effect: something like
f() ! a
is now a syntax error, because a function definition takes a command,
not a pipeline.

manage the "space left".
Previously, growstackstr()'s assumption causes problems with STACKSTRNUL()
where we want to be able to turn a stack into a C string, and later
pretend the NUL is not there.
This fixes a bug in STACKSTRNUL() (that grew the stack) where:
1. STADJUST() called after a STACKSTRNUL() results in an improper adjust.
This can be seen in ${var%pattern} and ${var%%pattern} evaluation.
2. Memory leak in STPUTC() called after a STACKSTRNUL().

slice they are on. When NANO_LABEL is not defined, the fstab
generates entries that specify /dev/ad0s1a. When NANO_LABEL is
defined, it generates /dev/usb/${NANO_LABEL}s1a. The prior code
created the file system with a label of ${NANO_LABEL}s1, leading to

Refuse to attach providers where the metadata provider size is

updates the provider size in the restored metadata to the correct
value.
