contrib/*: Support the "--help" and "--version" options
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.
