common: Add a global variable to for the default error source.

Browse source 
For the shared code parts it is cumbersome to pass an error sourse
variable to each function.  Its value is always a constant for a given
binary and thus a global variable makes things a lot easier than the
former macro stuff.
* common/init.c (default_errsource): New global var.
(init_common_subsystems): Rename to _init_common_subsystems.  Set
DEFAULT_ERRSOURCE.
* common/init.h: Assert value of GPG_ERR_SOURCE_DEFAULT.
(init_common_subsystems): New macro.
* common/util.h (default_errsource): Add declaration.
* kbx/keybox-defs.h: Add some GPG_ERR_SOURCE_DEFAULT trickery.
