bc: only check for ^C in bc_program_exec() main loop
...
Checking it in individual operations such as SQRT is not necessary
since they usually do not take very long to complete. We repeatedly return
to main loop.
TODO: re-add more fine-grained ^C checks - but only with examples where it is
actually needed. E.g. I suspect simplest ops like addition or compare won't need it.

vi: correctly detect when a deletion empties the buffer
...
Michał Berger has reported two issues:
- Repeatedly deleting and undoing the deletion of the last line
results in characters being lost from the end of the line.
- Deleting the bottom line twice then attempting to undo each of
these deletions results in a segfault.
The problem seems to be an incorrect test for whether the text buffer
is empty.

If busybox is compiled with FEATURE_VI_REGEX_SEARCH enabled, command

hush: allow hush to run embedded scripts
...
Embedded scripts require a shell to be present in the BusyBox
binary. Allow either ash or hush to be used for this purpose.
If both are enabled ash takes precedence.
The size of the binary is unchanged in the default configuration:
both ash and hush are present but support for embedded scripts
isn't compiled into hush.

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.

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.
