Giving portable semantics for spawning a process is difficult, and it is still difficult for users to writing a function for SPAWN_CB with portability, but gpgrt_spawn_process_fd gives the feature of spawning a process.

This is the just the basic code which should allow replacement of the parsers. A forthcoming patch will implement flags for options given in the global config file.

(run_emergency_cleanup): New. * src/visibility.c (gpgrt_add_emergency_cleanup): New public API. (gpgrt_abort): New public API. -- Libgcrypt uses its own assert function which makes sure to terminate the secure memory. This is safe as log as an assert is triggered internally in Libgcrypt. GnuPG runs emergency cleanup handlers right before log_fatal etc to tell Libgcrypt to terminate the secure memory. With the move of the logging function to gpgrt in gnupg 2.3 this did not anymore. Thus we now provide a mechanism in gpgrt to do right that. Eventually Libgcrypt can also make use of this. What this does not handle are calls to abort or failed asserts in external libraries or in libc. We can't do anything about it in a library because a library may not setup signal handlers.
