The -e option should only apply to swapon, and it should swallow all
errors/warnings when the device does not exist. So delete the flag
from the swapoff patch and unify the check in the swapoff path.

The user might be including options in their LDFLAGS (like -fuse-ld=gold)
that change the behavior of the linker and thus change the results of the
flag tests. Make sure we include the user's LDFLAGS when running these
tests so we filter out flags that will fail when used later on.

Where the POSIX shell allows functions to be defined as:
name () compound-command [ redirections ]
bash adds the alternative syntax:
function name [()] compound-command [ redirections ]
Implement this in ash's bash compatibility mode. Most compound
commands work (for/while/until/if/case/[[]]/{}); one exception is:
function f (echo "no way!")
The other two variants work:
f() (echo "ok")
function f() (echo "also ok")

We should bail-out if i2c_smbus_read_block_data() or

for the former and fix the existing for the latter.

Currently we're calling i2c_smbus_read_block_data() for both 'i' and 's'
mode parameters. If the bus doesn't support SMBus block mode, then the
i2c access ioctl() fails. Make i2cdump behave compatibly with upstream
version by calling i2c_smbus_read_i2c_block_data() for I2C block.

We currently read data twice in byte mode. Add a check to avoid calling

If the bus doesn't support SMBus Quick Write or Receive Byte commands
and we're running in auto mode all addresses will be skipped resulting
in an empty table being printed.
This is caused by not restoring the auto mode after it's been changed
for certain address ranges - we need an additional variable to hold the
temporary state.

If /tmp/test.sh is a script that tries to run a second script which
happens to be non-executable this:
command . /tmp/test.sh
causes a seg fault.
This is because clearredir is called in the error path to clear the
stack of redirections. The normal path then calls popredir, but popredir
fails when the stack is empty.

evalcommand always clobbers the exit status in case of an EXEXEC
which means that exec always fails with exit status 2 regardless
of what it actually returns.
This patch adds the missing check for EXEXEC so that the correct
exit status is preserved. It causes the test ash-misc/exec.tests
to succeed.

The exec builtin should return an exit status of 127 if the command
can't be found. It doesn't: it returns 2.
If the command builtin is used to source a script that runs a second
script that doesn't exist ash should issue an error. Instead it seg
faults.

Use a stupid linear search: we're also about to read all the
directories on PATH so efficiency isn't a big concern.
