95650a86d1 ash: allow popredir to be called if the stack is empty
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.

8c55dc79a7 ash: fix EXEXEC status clobbering
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.

Based on commit 7f68426 in dash git, by Herbert Xu.

e939856c87 ash: add tests for failures of the exec and command builtins
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.

82c2fad26c fbsplash: use virtual y size in mmap size calculations
The virtual y can be larger - and we can be even writing there since
we are taking into account the y offset. Avoids possible crash.
But use it only if set, seems it is not set if virtual area is not
