2d217799e8 build system: prevent duplicate applet names
The embedded script feature makes it easier to create applets with
duplicate names.  Currently in such cases the build succeeds but
the resulting executable doesn't work as the developer intended.

Catch duplicate names when the applet tables are being generated
and make the build fail.

7b42f8fc76 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.

v2: Remove a couple of unnecessary tests in embedded_scripts, as
    pointed out by Xabier Oneca.
    Drop the stripping of comments.

03ad7ae081 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).

3778898f97 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.

e6a63bf683 ash: ensure variables are fully initialised when unset
When a variable is unset by calling setvar(name, NULL, 0) the code
to initialise the new, empty variable fails to initialise the last
character of the string.

Attempts to read the contents of the unset variable will result
in the uninitialised character at the end of the string being
accessed.

For example, running BusyBox under Valgrind and unsetting PATH:

$ valgrind ./busybox_unstripped sh

v2: On the dash mailing list Harald van Dijk was kind enough to point
    out a flaw in my reasoning and provide an alternative patch.  Sadly
    his patch adds 2 bytes of bloat.  Using xzalloc to zero the whole
    string gives a bloat of -3 bytes.
