Improve version numbering.
* configure.ac: Use separate version number for all build types. (IS_VSD3_BUILD): New ac_subst to define the currently approved version. (MSI_VERSIONSTRING): New ac_subst to be used to construct the MSI version number. (DOCKERBUILD): Remove. * build.sh: Remove "gnupgtag" and related options. * autogen.rc (autogen_use_force): New. * autogen.sh: Take care of that option.
This will help us to keep the version numbers in one place. A new
buildtype vsd3 is introduced to be used for the next vsd version 3.4.
Beta versions will now have a fixed micro version of 90 in the MSI
installer. The core gpg4win NSIS installer keeps the usual beta
numbering scheme.
