 * 2 for fatal errors and halts

This is probably completely unused by now, as vservers have been
superseeded by alternative technology for many years already.

This fixes cases where the day component of the when parameter resolved
to a non-zero padded integer under 10, such as "when = 1st at 01"

The comparison against the nowday variable failed consistently since
the date command format used always returned a zero-padded two digit
integer.

The solution chosen is to avoid generating nowday with zero-padding and
remove any zero-padding from whenday parameter using a more thorough
sed pattern which now also removes any non-alphanumeric characters from
the string.

The capital-V is more common as shorthand for --version, since many
commandline tools use -v as a shorthand for --verbose.

At build time, we use the version number provided by configure.ac, which
is updated upstream when there is a new release.

Fixup on commit 57190c20.

Thanks to Olivier Berger for the patch.

The format option of pg_dump enables tar and custom archive file formats in
addition to the default plain-text file containing SQL commands.

When either the tar or custom format are selected the behaviour of database=all is changed to no longer dump a single file via pg_dumpall. Instead pg_dumpall
is called once to export the "global" data (roles & tablespaces) and then
pg_dump is called once for each non-template table in the database.

To support the GZIP and GZIP_OPTS variables in backupninja and to give the
default --rsyncable gzip compression flag a chance at working on a PostgreSQL
backup, the custom output is forced to not use compression. Instead compression
is done via a pipe to gzip. Hopefully this benefits rsync and rdiff-backup
style backups for reduced backup and storage costs that outweigh the
restoration ones.

... so that this option can be disabled on systems that don't support it.
This also allows to use another compression program, such as pbzip2 on SMP
machines (closes Roundup bug #2405).

reportspace: skip non-directories and places that don't exist on the local filesystem (Closes: #536049)

... hoping it will help supporting *BSD some day.

The modelines added match the emacs lines already present and also set
the filetype to sh (just like the emacs lines).

Previously, there were many indentation styles in use: Real tabs, 2, 3
or 4 spaces, mixing these within the same file, function or even within
a single line.

This commit changes all bash scripts in the handlers, src and lib dirs
to use consistent indentation: three spaces are now used everywhere.
Other files (e.g. Makefiles) are left untouched.

Additionally, this commit removes all trailing whitespace.
