Programs can freely define the value of argv0 and thus it means nothing.
Instead, use the bash-specific variable explicitly designed to safely
and accurately reference the name of the currently sourced file.
This also fixes the case where simple debugging mechanisms like using
"bash -x foo" tried to treat "foo" as the unqualified $0 and therefore
broke horribly due to lack of pathnames.

- Use `read -r` instead of other forms of read or looping
- Use arrays instead of strings with whitespaces.
- In one instance, use ${var%%.*} instead of $(echo $var|cut -f. -d1)
This involves extending the signature of lib/common.sh's `stat_busy()`,
`lock()`, and `slock()`. The `mesg=$1; shift` in stat_busy even suggests
that this is what was originally intended from it.
In cases where there is no license specified, the file is tagged as
"License: Unspecified". Obviously, that is not ideal, but it
highlights the fact, and I hope that it encourages whoever has the
authority to specify the license to do so.
On that note, to anyone who may have the authority to specify the
license of files in devtools: the current licence of many files is
GPLv2 with no option for later versions; I impore you to re-license
them to have the "or any later version" option.
The usage messages now begins with a "Usage:", i.e. capitalized and with a colon. Fixes FS#26956.

We already fixed a couple of these in previous patches - this one should
replace all remaining uses of single brackets ("[") by double brackets.
Also, use arithmetic evaluation instead of conditional expressions where
appropriate and make use of "-z" and "-n" instead of comparing variables
to empty strings.

This build system overhaul allows for adding (define-style) macros to
our scripts. All source files are now suffixed with ".in" to clarify
that they might contain unprocessed defines. The Makefile provides a new
rule to preprocess source files and generate proper output scripts.
Also, add a "@pkgdatadir@" define (as used in GNU Autotools) and use it
instead of hardcoded paths to "/usr/share/devtools" everywhere. We
missed this when adding PREFIX support to the build system in commit
35fc83ce7d.
