71df2d3589 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.

77a6678c42 dd: add 'fullblock' iflag
Adds a fullblock iflag for improved compatibility with GNU dd.
The new iflag can be used to ensure that dd calls retrieve the

488dd70869 fix !ENABLE_FEATURE_GETOPT_LONG build. Closes 3775
When compiling with !ENABLE_FEATURE_GETOPT_LONG, busybox still tries
to include getopt.h which is not available; for example with uClibc
when !UCLIBC_HAS_GETOPT_LONG.  getopt.h is only required
for the _long set of functions.
