BusyBox has support for embedded shell scripts. Two types can be
distinguished: custom scripts and scripts implementing applets.
Custom scripts should be placed in the 'embed' directory at build
time. They are given a default applet configuration and appear
as applets to the user but no further configuration is possible.
Applet scripts are integrated with the BusyBox build system and
are intended to be used to ship standard applets that just happen
to be implemented as scripts. They can be configured at build time
and appear just like native applets.
Such scripts should be placed in the 'applets_sh' directory. A stub
C program should be written to provide the usual applet configuration
details and placed in a suitable subsystem directory. It may be
helpful to have a configuration option to enable any dependencies the
script requires: see the 'nologin' applet for an example.

Similar code to unpack embedded data is used to decompress usage
messages, embedded scripts and the config file (in the non-default
bbconfig applet).
Moving this code to a common function reduces the size of the default
build and hides more of the internals of libarchive.

To assist in the deployment of shell scripts it may be convenient
to embed them in the BusyBox binary.
'Embed scripts in the binary' takes any files in the directory
'embed', concatenates them with null separators, compresses them
and embeds them in the binary.
When scripts are embedded in the binary, scripts can be run as
'busybox SCRIPT [ARGS]' or by usual (sym)link mechanism.
embed/nologin is provided as an example.

Since we're comparing the return value to a smallish integer anyway, we
might as well use that bb_strtou() returns UINT_MAX for malformed
input. Referencing errno is kinda bloaty on glibc.
While NSIG is not in POSIX, we do already rely on it being defined,
compile-time const and smallish, since arrays in struct globals_misc are
defined in terms of it.

When an application documents that it responds such and such to
SIGRTMIN+n, that almost always means with respect to the libc-provided
SIGRTMIN. Hence I disagree with the "more correct" in commit
7b276fc17594. In any case, this is rather unfortunate:
36
34
(the first shell is bash). We probably can't change default behaviour
after 7 years, but at least we can provide a config option.
We avoid a little code generation (repeated calls to
__libc_current_sigrtmin) by stashing SIGRTMIN/SIGRTMAX in local
variables, but it does cost ~50 bytes. The next patch serves as penance
for that.

When deleting a directory, the directory should not be removed if the
file in the subdirectory fails to be deleted.
Background information:
When I tested the kernel using LTP (linux-test-project).I found the
mv command have some issue. The LTP test case use the mv command to
move the directory t1 in the cgroup file system to the /tmp directory.
becase files in the cgroup file system are not allowed to be removed.
so the mv reported "Permission denied", but I used the ls command to
view the results and found that the directory t1 had been removed
from the cgroup file system. For the same test case, I used the mv
tool in the GNU coreutils, and the directory t1 will not be removed.
the following testcase use busybox mv:
/ # mount -t cgroup -o cpu cgroup /cpu
/ # cd /cpu
/cpu # mkdir -p t1
/cpu # ls
cgroup.clone_children cpu.cfs_period_us cpu.stat t1
cgroup.procs cpu.cfs_quota_us notify_on_release tasks
cgroup.sane_behavior cpu.shares release_agent
/cpu # mv t1 /tmp
mv: can't remove 't1/cgroup.procs': Operation not permitted
mv: can't remove 't1/cpu.cfs_period_us': Operation not permitted
mv: can't remove 't1/cpu.stat': Operation not permitted
mv: can't remove 't1/cpu.shares': Operation not permitted
mv: can't remove 't1/cpu.cfs_quota_us': Operation not permitted
mv: can't remove 't1/tasks': Operation not permitted
mv: can't remove 't1/notify_on_release': Operation not permitted
mv: can't remove 't1/cgroup.clone_children': Operation not permitted
/cpu # ls
cgroup.clone_children cpu.cfs_period_us cpu.stat cgroup.procs
cpu.cfs_quota_us notify_on_release tasks cgroup.sane_behavior
cpu.shares release_agent
/cpu #
This patch fixed it, don't call rmdir if remove_file return failure,
and under certain file systems, the mv could work normally.

This necessitates switch from libc FILE api to a simple
homegrown replacement.
The change which fixes the bug here is the deleting of
restore_redirected_FILEs();
line. It was prematurely moving (restoring) script fd#3.
The fix is: we don't even _want_ to restore scrit fds,
we are perfectly fine with them being moved.
The only reason we tried to restore them is that FILE api
did not allow moving of FILE->fd.
