build system: prevent duplicate applet names
The embedded script feature makes it easier to create applets with

the resulting executable doesn't work as the developer intended.
Catch duplicate names when the applet tables are being generated

Tweaks to build process for embedded scripts
- Force a rebuild if a script in applets_sh is changed.
- Move the dummy usage messages for custom applets to usage.h and
change the name from 'dummy' to 'scripted'.
- Hide an error from gen_build_files.sh if an embed directory exists
but is empty.
- Tidy up embedded_scripts script.

ash: reset tokpushback before prompting while parsing heredoc
The parser reads from an already freed memory location, thereby causing
unpredictable results, in the following situation:
- ENABLE_ASH_EXPAND_PRMT is enabled
- heredoc is being parsed
- command substitution is used within heredoc
Examples where this bug crops up are (PS2 is set to "> "):
$ cat <<EOF
> `echo abc`
> EOF
-sh: O: not found
$ cat <<EOF
> $(echo abc)
> EOF
-sh: {garbage}: not found
The presumable reason is that setprompt_if() causes a nested expansion when
ENABLE_ASH_EXPAND_PRMT is enabled, therefore leaving "wordtext" in an unusable
state. However, when parseheredoc() is called, "tokpushback" is non-zero, which
causes the next call to xxreadtoken() to return TWORD, causing the caller to
use the invalid "wordtoken" instead of reading the next valid token.
The call chain is:
list()
-> peektoken() [sets tokpushback to 1]
-> parseheredoc()
-> setprompt_if()
-> pushstackmark()
-> expandstr()
-> readtoken1()
[sets lasttoken to TWORD, wordtoken points to expanded prompt]
-> popstackmark() [invalidates wordtoken, leaves lasttoken as is]
-> readtoken1()
-> ...parsebackq
-> list()
-> andor()
-> pipeline()
-> readtoken()
-> xxreadtoken()
[tokpushback non-zero, reuse lasttoken and wordtext]
Note that in almost all other contexts, each call to setprompt_if() is preceded
by setting "tokpushback" to zero. One exception is "oldstyle" backquote parsing
in readtoken1(), but there "tokpushback" is reset afterwards. The other
exception is nlprompt(), but this function is only used within readtoken1()
(but in contexts where no nested calls to xxreadtoken() occur) and xxreadtoken()
(where "tokpushback" is guaranteed to be zero).

Treat custom and applet scripts as applets
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.

libbb: optionally honour libc provided SIGRTMIN/SIGRTMAX in get_signum()
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.

remove_file: don't call rmdir if remove_file return failure
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.

whois: fix a possible out-of-bounds stack access
If fgets() returns incomplete string, we replace NUL with
'\n', and then trim() runs on a non-NUL-terminated buffer.
Prevent that.
While at it, bump buffer from 1k to 2k.

chcon: fix issues with recurse and retval for retained files
- recurse is not acting as expected (looks like broken old code)
- when not using verbose output, return value for retained files is 1,
which is not expected.
