Add new interface gpgrt_get_syscall_clamp.

* src/visibility.c (gpgrt_get_syscall_clamp): New.
* src/gpg-error.vers, src/gpg-error.def.in: Add function.
* src/gpg-error.h.in: Ditto.
* src/estream.c (_gpgrt_get_syscall_clamp): New.

This function can be used by other libraries to set their own system
clamp functions.
