Prevent the build system from hiding our ABI.

Unfortunately --exclude-libs (now passed globally) clobbers our
version script, so we have to prevent the build system from using this
flag.

Import scsi headers.

Linux's scsi headers are a mix of userspace-facing and kernel-facing
declarations that can't be directly used by userspace.  The glibc
maintainers manually copy-and-pasted these definitions into their own
scsi headers and haven't substantially updated them in 15 years.  musl
has a similar set of definitions in its scsi headers.

using the updated generation script so that the single modified scsi.h
takes the place of the non-modified one.

Move tzdata scripts from bionic to external/icu

The scripts affect files in external/icu, bionic
and the generated files affect libcore. The files must
be updated together so there is no "obvious" home.

OEM developers seem to want to update ICU
themselves and have been asking how. Moving the
scripts to external/icu and splitting the ICU generation
code into a sub-script they can run makes some sense.
