Add "--help"/"-h" and "--version"/"-V" support to all contrib scripts.
Also, update scripts that used "-v" as a short option for "--version"
and use "-V" for the sake of consistency.
Additionally:
* Move version and usage messages to separate convenience functions in
all scripts.
* Add a workaround to paccache to support "--help" and "--version". This
should be replaced by a proper POSIX-compliant command line parser
that supports long options in a future patch.
* Add a "$myver" variable to all scripts and use it whenever we refer to
the program version (e.g. in version messages). Also, use the pacman
version number everywhere instead of using a different versioning
scheme for each contrib script. This is achieved by adding a
"PACKAGE_VERSION" placeholder that is replaced by sed(1) when the
script is built.
* Ensure we always return with exit status 0 if "--help" is used and
return with exit status 1 if we display the usage message due to
invalid arguments.
* Add "AUTOMAKE_OPTIONS = std-options" and add all scripts to
"bin_SCRIPTS" to make `make installcheck` check that installed scripts
actually support the "--help" and "--version" options.

Add a read-only variable "$myname" to every contrib script and hardcode
program names instead of relying on "$0". The variable name "$myname"
was chosen because it is already used in pacman and because we use
"$myver" to specify the program version in the official scripts.

vim recognises what type of shell script it's dealing with by looking at
the shebang. If detection fails it falls back to sh which doesn't
support some bash features. Adding a normal, possibly broken, shebang
which gets fixed by the Makefile allows vim to detect bash syntax.

BASH is defined when you are actually using bash during configure, which
sucks because it ends up being '/bin/sh', messing up all of our scripts.
Change the name of the variable we use in configure, and also ensure we get
a full path to the executable by using AC_PATH_PROGS rather than
AC_CHECK_PROGS. Finally, change the variable name everywhere we use it.
