Put blocking calls into Libgpg-error's system call clamp.
* src/gcrypt.h.in (GCRYCTL_REINIT_SYSCALL_CLAMP): New.
* configure.ac: Require Libgpg-error 1.25. Set version number to
1.8.0.
* src/gcrypt-int.h: Remove error code emulation.
* src/global.c (pre_syscall_func, post_syscall_func): New.
(global_init): Call gpgrt_get_syscall_clamp.
(_gcry_vcontrol) <GCRYCTL_REINIT_SYSCALL_CLAMP>: Ditto.
(_gcry_pre_syscall, _gcry_post_syscall): New.
* random/rndlinux.c (_gcry_rndlinux_gather_random): Use the new
functions.
