portable: propagate AM_CFLAGS/AM_CPPFLAGS Compiling with warnings and certain compiler flags is important for security and bug-free code. Set a bunch of warnings via AM_CFLAGS in a common Makefile, and let those values propagate to all other Makefiles. While here, also fix the version string to remove quotes.

libexec: honour libeexec path for helpers libexec is a common path which is understood by autotools, and should be honoured. Patch from Christian "naddy" Weisgerber

portable: add CHANGELOG Although there is already a CHANGES file, the CHANGELOG is used to indicate any -portable specific changes which have happened for that release. All version numbers in -portable correspond to their OpenBSD counterpart.

dist: rework files for distcheck Rather than having a toplevel EXTRA_DIST target in the toplevel Makefile.am file, move the relevant files to their own Makefile.am locations.

regress: port cmdline tests This commit introduces the 'make tests' target which will run the cmdline/* tests.

enable gotadmin Add gotadmin to configure.ac, etc., so it can be built and installed. OK thomas.adam

automake: Fix path to libexec directory The got_lib_privsep.h header expects the path to the libexec directory to be called GOT_LIBEXECDIR. At the moment it always falls back to using /usr/libexec. Fix what looks to be a typo.

portable: initial Linux compilation This commit modifies the GoT main branch to be able to compile it under linux.
